rotary dryers

Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.

Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.

The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.

Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:

Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.

5 ways to know it's time to get a new washing machine - cnet

Washing machines, on average, last around 10 years, according to Consumer Reports. If your washer is reaching the threshold, or it's been having some problems, here are some signs the end may be near.

If you've covered those bases and the washer still leaks, you may have a crack in the tub. This is a major fix, and in most cases it would be more cost-effective just to buy a new washer, especially if it's getting close to its 11th birthday.

If you have an older front-loading washer, you may have found it gets a certain... aroma on a regular basis. Some Whirlpool, Kenmore and Maytag front-loading washers made between 2001 and 2010 may fail to adequately self-clean themselves. This can lead to mold or mildew growth inside of the washer that causes a stink.

A defective part may cause certain top-load Samsung washers manufactured between March 2011 and April 2016 to break apart. The company is offering a free in-home repair or a rebate that can be used for buying a new washer from any manufacturer you choose. If your machine is on the older end of the affected washers, you may just want to opt for the rebate.

You can check to see if your washer is affected by typing in your model and serial number on this site. You can find this information on the rear of the washer. On some 2016 models the info will be under the lid.

There are several causes of a loud dryer. First, check to make sure that the dryer is level. If it wobbles when you push down on one of the corners, it's not level. Stick something under one of the feet to level it out, or if it has adjustable feet, unscrew the short one so it is long enough.

If that doesn't work, the drum or motor mount may need to be tightened. In this case, you'll need a professional. Get an estimate before committing to any work, though. If the repair is costly and your washer is old, it may just make sense to get a new one.

What is the difference between older and newer models exactly? New Energy Star-certified clothes washers use around 45 percent less water and 25 percent less energy than regular washers. That adds up to a savings of around $45 per year in utility bill costs and 3,000 gallons of water per year. Energy Star estimates that if your washer is over 10 years old, it could be costing you around $210 a year, on average.

rotary dryer machine design and working principle - sunco machinery

For evaporating the moisture from the wet raw material, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. The rotary dryer machines has the direct heating type, in direct heating type. Direct heating type rotary dryer machine are used to apply heat / hot air to contact and heat the raw material such as sawdust, wood chips, chicken manure, silica sand, wood shavings, palm fibre, fly ash, etc. If it is not suitable to apply heat direct to heat and dry the raw material, then rotary dryers of indirect heating design can be furnished so that the heated hot gases will not come in direct contact with the wetraw material. Rotary Dryer is a simple, inexpensive unit forreducing the moisture content from the wet material. Several types ofrotary dryer machine design can be applied for drying different kinds of raw material. RotaryDryerMachine Working Principle: Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that the material can inflow therotary dryersmoothly. There is one hot air furnace supply the hot flue gas for therotary dryerusually. The fuel can be waste wood, coal, natural gas, diesel, etc. Therotarydryercylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into therotary dryercilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in therotarydryercylinder body, the lifting plates inside therotary dryercilinder makes the material up and down to contact with the hot flue gas completely. Thus, the moisture inside the wet material is evaporated into water vapour, and finally we get the dried materials. There is one high pressure induced draft fan is used to suck out the water vapour out of therotarydryerduring the drying process. Finally the water vapour with some dust goes into the cyclone dust collector. In the cyclone dust collector, the dust is seperated from the water vapour and falls down from the bottom of the cyclone dust collector; the water vapour leaves the cyclone dust collector from the top pipe of the cyclone dust collector, and finally goes into atmosphere through the chimney. At the end of therotary dryer, using one belt conveyor to transport the dried material into trucks or storage room directly. The rotarydryer seems very simple, but in fact it is one whole drying system, and the drying system should be designed according to: --- The features of raw material, for example the wet sand has surface water which is easier to be dried, but the wood chips has inner water which is more difficult to be dried. ---Initial moisture content(%) of the wet material. ---Output moisture content(%)the dried material needed. ---Bulk density (kg per cubic meter) of the wet material. ---Input capacity (ton per hour). ---Output capacity(ton per hour). ---Fuel Choice such as coal, waste wood, natural gas, diesel, etc. ---End use of the dried product. When the above information are clear, then Sunco Machinery engineers can calculate and design the suitable and reasonablerotary dryer systemfor the customers accordingly.

ar pro series rotary phase converter - american rotary

In this video, we give you an overview of the AR, AD, ADX, and AUL lines of American Rotary Phase Converters. Learn the difference between each model and which might be best for you and your equipment.

American Rotary engineers the entire phase converter system to provide optimum performance. Our soft start generatorand MicroSmartTM controller combine to make the most powerful and precise rotary phase converter on the market.

The focus of American Rotary, is always on innovative engineering, product development, and outstanding customer service. The results are great American made phase converters that work flawlessly, provide unparallleld performance and are easy to install, all at an affordable price.

American Rotary's breakthrough design of the MicroSmart controller (AD, ADX) allowed it to create the first true digitally controlled phase converter in the industry. Its digital accuracy provides an impressive ability to adapt to changing loads, sagging voltages and gives our phase converters the feel and performance you expect from high precision machines.

The single largest component in a phase converter is the American Rotary Soft Start Generator. American Rotary's engineering departments spent over 2 years engineering the perfect generator for a Rotary Phase Converter, and its patent technology is the best in the industry. American Rotary's custom generator is one of a kind in our industry and outperforms the standard motor/idlers found on a typical phase converter.

American Rotary's custom designed generator features a Soft Start using only 1/3 of the starting current to get the idler generator started unlike the traditional off-the-shelf 3 phase motors found in typical motors with shafts removed found in typical phase converters. This generator provides precise power, runs cooler for longer life and can run continuously from a no load condition through full load.

The induction generator, by design, balances the power factor and phase angle which ultimately leads to true, undistorted sinewaves and more stable voltage. Typical phase converters that use modified motors have distorted sinewaves resulting in harmonics causing high operating temperature on the load motor, putting undue stress on your equipment.

Major manufacturers like American Rotary, Phase-A-Matic, Ronk, and Kay use Open Drip Proof (ODP) style designs. Open designs run cooler, quieter, use less power and can maintain voltage better than TEFC Designs. Only trust Open Drip Proof designed phase converters to run your valuable equipment.

A screen shot of an oscilloscope shows the difference in voltage drop using a modified 3-phase motor (GREEN) vs. using a American Rotary Soft Start Generator (RED). This is especially important when running voltage sensitive equipment such as CNC machines, welders and other rectified or computer loads. Stable voltage keeps your equipment protected and running perfectly.

American Rotary's magnetic starter provides the means to continuously control your American Rotary phase converter remotely, from multiple locations or in conjunction with automatic equipment. See the Expandable Design Remote Start Feature for more information on remote start options.

The American Rotary manufacturing team assembles its starter modules using torque drivers that are tested and certified as a requirement for UL certification at our Wisconsin manufacturing plant. Every control panel American Rotary builds passes over 50 criteria for quality certification before it ships your new phase converter to you!

American Rotary starters are custom designed to meet even the most difficult loads and the most stringent standards. We oversize the starters to ensure they can handle the entire starting current and continuous load. All American Rotary phase converters undergo rigorous simulation and testing in its R&D department to ensure your equipment and operators are safe and protected.

A starter is not designed or rated to be the safety disconnect. Be aware of phase converters that claim their starter disconnects all three lines of output. A properly used starter only controls the start/stop of the phase converter and does not disconnect the single phase lines. American Rotary will always put your safety first.

All American Rotary Phase Converters are capable of phase synchronization for increased capacity. Converters can be daisy chained together to double, triple, quadruple your power. Call or email the American Rotary technical staff for more information on available options.

As you add more equipment or change the type of equipment you run, the MicroSmart controller adapts with your shop needs. Powering your shop or business with a SMARTConverter (AD, ADX) ensures your equipment gets the right power at the right time, even as your business changes and grows.

All American Rotary Phase Converters are designed to work with wired and wireless remote starts. Our long range radio frequency remote starter and receiver works seamlessly with our latching full current magnetic starter to remotely control your converter. Wireless remotes feature 500 range and include high gain, omni directional antenna and a key FOB or wall mount transmitter. You can also control your converter with our wired remotes!

American Rotary realizes that some equipment just isnt meant to be hard wired. So it gave every phase converter a space for a twist-lock, 3-phase receptacle and a flush mount 3-phase breaker Great for welders, battery chargers, mobile jobsite converters and more.

Designed to meet UL minimum space requirements, American Rotary enclosures have removable sides so that the oversized terminal blocks can be accessed with ease. The cover is hinged and can be easily removed.

Copper Aluminum Alloy and Nylene terminal blocks are specifically designed and molded for American Rotary phase converters in order to provide easy organized connections for a carefree, UL compliant installation. Terminal blocks are clearly marked for trouble-free installations.

No drilling or punching needed! All the necessary knockouts for installation are provided and powder coated to prevent rust. The knockouts are sized for the maximum anticipated conduit for proper wire gauge per NEC.

The design flexibility and time savings features that laser cut steel provides is an important part of the quality of an American Rotary phase converter. From knockouts for breakers and receptacles, to perfectly mitered corners, laser manufacturing results in a longer lasting, better quality product.

The American Rotary MicroSmart Controller is a patent technology which provides precise control of the phase converter. It monitors the voltage every 50 milliseconds providing better voltage control, prolonging the life of the converter, handles significantly more load capacity (ADX and AI), and enabling several failsafe features that are only available on American Rotarys SMART Series phase converters. (AD, ADX, and AI units only)

Smart Series digital rotary phase converters (AD, ADX, and AI) run on our MicroSmart Controller. This custom designed microprocessor delivers the right power at the right time in both start-up and run mode. The MicroSmart controller monitors and takes a sampling of the voltage every 50 milliseconds on all three lines of the output voltage.. (AD, ADX, and AI units only)

American Rotary has invested extensively in research and design to create the state of the art MicroSmart Digital Controller. Other so called digital rotary phase converters use an off the shelf voltage relay that does not monitor the voltage like the MicroSmart Controller. (AD, ADX, and AI units only)

All American Rotary Smart Series phase converters are designed to grow with your business. Our converters are engineered to allow numerous upgrade options, including; Hardware, Software and Kit upgrades. You can also run our phase converters in parallel and double your power to adapt to your changing needs. Need more power? More precise power?

refrigerated and desiccant dryers for sale | quincy compressor

Quincy refrigerated dryers play the important role of removing condensation from compressor systems. Without a dryer, moisture can accumulate in a compressor. With this moisture comes dirt and other particulate matter, which can cause oxidation and other types of premature wear on delicate compressor components. A refrigerated dryer eliminates the problem by cooling moisture in the air to approximately 37F, where it condenses and can be removed from the compressor system by way of an automatic drain.

Quincy manufactures four main refrigerated dryer product lines: the QPNC non-cycling dryer, the QED cycling dryer, the QPVS variable speed dryer, and the QRHT compact high temperature dryer. The QPNC uses a two-stage heat exchanger configuration to deliver consistent performance when handling smaller, constant loads. Key features of the QPNC include an easy-to-use control panel that allows you to adjust the system for maximum efficiency with zero loss drains. Depending on their configuration, QPNC refrigerated dryers can provide a maximum 230 psig pressure at volumes between 10-3000 CFM.

QED cycling dryers reduce energy usage by cycling the cooling system on and off as demand decreases. They feature a three-stage configuration with a heat exchanger that allows the refrigeration system. Our cycling dryers do not require cooling in a glycol bath and are designed to automatically adjust as the operating environment changes.

QPVS premium variable speed dryers are the most energy efficient dryers in the market. These dryers speed up or slow down based off incoming air demand. This allows for a constantly stable dew point even in harsh environments. Also, because of their smart compact design, the QPVS dryers have a smaller physical footprint, and lower CO2 emissions than thermal mass and non-cycling dryers.

Finally, our QRHT product line features a space-saving design that combines an air-cooled aftercooler, refrigerated dryer, moisture separator, zero-loss drain and coalescing filter in one device. A total system solution for your air cooling needs, the QRHT delivers up to 232 psig at between 25 and 125 CFM.

All Quincy refrigerated dryers can be counted on to deliver exceptional performance in any situation. Our products are backed by a comprehensive warranty as well as support from our nationwide team of compressed air experts.Contact a representativein your area or visit individual product pages using the following links:

Desiccant dryers differ from refrigerated dryers in that, rather than cooling air to remove moisture, they rely on a desiccant to adsorb potential contaminants. Quincy manufactures four main product lines of desiccant dryer. Our heatless dryers (QHD series) are affordable to purchase and operate, and they feature microprocessor controls and 15% purge rates.

For heavier-duty applications, upgrade to our heated (QHP) series of products. These dryers require less air to regenerate the desiccant and are available with the optional Quincy MicroBurst Regeneration (MBR) system. When set up properly, a QHP desiccant dryer equipped with MBR technology can cut purge requirements in half, saving you money and helping you realize a return on your investment in as little as five months.

Other available products include the QBP blow purge desiccant dryer, which is our most efficient dryer, with purge rates down to 1.75%. QBP dryers are also NEMA-4 compliant and feature some of our lowest operating and maintenance costs. We also offer the QMOD and QMD. These include a modular heatless system for light-duty use.

Quincy compressors are complemented by a wide selection of dryers and accessories. Working together, our products form a complete solution for all your compressed air needs. Keep reading to learn more.

manufacture of pharmaceutical tablets

The design and manufacture of pharmaceutical tablets is a complex multi-stage process whereby formulation scientists ensure that the correct amount of drug substance in the right form is delivered at the appropriate time, at the proper rate and in the desired location with its chemical integrity protected to that point. Most drug substances do not possess the required properties which give satisfactory flow from the hopper to the die cavity of tablet presses. As a result, they are subjected to pre-treatment either alone or in combination with suitable excipients to form free-flowing granules that lend themselves to tabletting.

Tablets are commonly manufactured by wet granulation, dry granulation or direct compression. These methods may be considered to consist of a series of steps (unit processes) weighing, milling, mixing, granulation, drying, compaction, (frequently) coating and packaging. Regardless of the method used the unit processes weighing, milling and mixing, are the same; subsequent steps differ.

In addition to the job-specific responsibilities of these personnel, all manufacturing employees must be versed and trained in Current Good Manufacturing Practices (CGMPs) and in the appropriate Standard Operating Procedures (SOPs) governing their area.

Tablets in addition to the therapeutic agent(s) also contain excipients that are required to ensure satisfactory production process. These materials which are inert may be added to the drug substance to increase its bulk and give those desirable properties lacking in the drug substance alone. Depending on the intended use, tablet excipients may be subcategorized into:

Many excipients used in tablet formulation are multi-functional that is, they may serve more than one function and thus can affect the properties of powders or tablets in various ways at varying concentrations.

All excipients used in tablet formulation may not be present in all tablet formula. Some such as lactose, stearates, microcrystalline cellulose are common to the vast majority of tablets. Excipients used in tablet formulations include binders or granulating fluid, diluents, disintegrants, lubricants, glidants, colourants, sweeteners, flavourants, adsorbents, and surfactants.

Quality control of tablet raw materials (APIs and excipients) is one of the main tasks of the quality control unit in any drug manufacturing industry. Raw materials described in monograph of relevant Pharmacopoeia must undergo the necessary tests as stated in the monograph. It is often sufficient if identification testing is conducted on the individual packages/containers and content and purity determination in mixed samples.

Every manufacturer has the opportunity to carry out further testing if they deem it necessary for guaranteeing a smooth-running production process or a very high-quality product. Starting materials are released only after their quality are established or judged as satisfactory. Raw materials that fail the quality control test are rejected and returned to the supplier.

Any risks that may emanate from starting materials of inappropriate quality must be avoided to prevent product failure and to ensure a consistent level of quality, as well as safety in consumer and industrial products.

Wet granulation is a widely used method for the production of compressed tablet. It is essentially a process of size enlargement involving several steps and the use of an adhesive substance known as binder. The granules produced using this method of granulation has a greater probability of meeting all the physical requirements for tablet formation.

The formation of granules by compacting powder mixtures into large pieces or compacts which are subsequently broken down or sized into granules (often referred to as dry granulation, double compression or pre-compression) is a possible granulation method which, however, is not widely used in the manufacture of tablets. This method is used when tablet excipients have sufficient inherent binding properties. The procedure can also be used as a means to avoid exposure of drug substances to elevated temperatures (during drying) or moisture. Double compression method eliminates a number of steps but still includes weighing, mixing, slugging, dry screening, lubrication, and compression of granules into tablets. Compaction for the dry granulation process is generally achieved either by slugging or roller compaction.

In this method, the powder mix is compressed into a soft large flat tablet (about 1 inch in diameter) using a tablet press that is capable of applying high stress. Following this, the slugs are broken by hand or milled using conventional milling equipment to produce granules of the required size. Lubricant is added in the usual manner, and the granules then compressed into tablets. Aspirin is a good example of where slugging is satisfactory. Other materials, such as aspirin combinations, acetaminophen, thiamine hydrochloride, ascorbic acid, magnesium hydroxide, and other antacid compounds, may be treated similarly.

Results similar to those accomplished by the slugging process are also obtained with powder compactors. In roller compaction method, the formulation ingredients are mixed and are passed between high-pressure (oppositely) rotating rollers that compress the powder at 1 to 6 tons of pressure. The compacted material is then milled to a uniform granule size and compressed into tablets after the addition of a lubricant. The roller compaction method is often preferred to slugging. Excessive pressures that may be required to obtain cohesion of certain materials may result in a prolonged dissolution rate.

As its name implies, direct compression involves direct compression of powdered materials into tablets without modifying the physical nature of the materials itself. The technology involved in this method assumes great importance in the tablet formulations, because it is often the cheapest means, particularly in the production of generics that the active substance permits. Direct compression avoids many of the problems associated with wet and dry granulations. Its successful application in tablet formulation rests on two fundamental issues:

Before tablets are sent out for distribution, they are usually packaged using appropriate packaging materials. The type of packaging material used is a matter of choice and is dependent on several factors including:

Tablets are commonly packaged using blister and strip packs and are kept in places of low humidity, and protected from extremes temperature. The packaging provides excellent environmental protection for each unit of tablet, coupled with an aesthetically pleasing and efficacious appearance. Blister and strip packaging also provide some degree of tamper resistance to the dosage form.For larger quantities delivered to the pharmacist, glass or plastic bottles, metal containers, cartons, or paperboard drums may be used along with polyethylene liners, where necessary, to give added protection from moisture. If cotton wool stuffing is used under these circumstances it is an advantage for it to be external to the liners so that any moisture that it contains does not gain access to the tablets. Tablets that are decomposed when exposed to moisture can also be packaged with a desiccant packet. Light sensitive tablets are packaged in light-resistant containers. With a few exceptions, tablets that are properly stored will remain stable for many years.

rotary drum dryer machine overview

When it comes to drying solid bulk materials, Baker-Rullman direct heat rotary drum dryer machines have been chosen for their rugged build, ultimate reliability and excellent ROI. Our direct heat rotary drum dryer machines rely on contact between the material and process gas to dehydrate a very broad variety of materials. The unique triple-pass dryer design is recognized for its efficiency, and ability to produce a consistent product output over extended operational periods. In the rotary drum dryer process, combusted gases mix with clean, heated air. The wet bulk material is propelled through the system via a hot gas air stream. The material is continuously lifted by the cylinder flights and showered through the concurrent stream of hot gases. The three full-length interlocked concentric cylinders rotate together to create the highest velocity possible in the inner-pass. As lighter particles quickly lose 60% of their moisture and move out of the cylinder, heavier/denser particles are retained until they also lose 60% of their moisture. Known for our industrial innovation and engineering expertise, Baker-Rullman is a worldwide leader in rotary drum dryer machine manufacturing, installation knowledge, drum dryer reconditioning services, and network of used drum dryers and portable rotary drum dryers rentals.

high quality rotary dryers machine - gem rotary dryer

When rotary Dryer is operating, it shall be in direct contact with heated gas. The dryer consists of a large rotating cylindrical tube. In order to convey the material through the underside of dryer, the dryer should be slanted slightly to ensure that the discharge end is lower than the end of material feed .

Material shall be dried to enter the dryer. When the dryer is rotating, a series of internal fins will lift the material by lining the inner wall of the dryer. When the material reaches certain height to roll the fins back, it will be fell back to the bottom of the dryer, then passing through the hot gas stream as it falls. This gas stream can either move toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be composed of a mixture of air and combustion gases from a burner, and in which case the dryer is known as a direct heated dryer. Alternatively, the gas stream may be made up of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases are not permitted to enter the dryer, the dryer shall be called an indirect-heated type. Indirect heated dryers are commonly used when product contamination becomes a concern.

Sugar is inclined to clump and stick together; the tumbling action, in combination with the showering action from the dryers internal flights, help break up any clumps, and for this reason, sugar producers have come to rely on rotary dryers as their drying equipment of choice.

Biomass materials can vary across types and even from within the same source of material. Therefore, rotary dryers are often selected because of their reliability in working with such a variance in feedstock.
