hammer mills and material size reduction equipment

The first product Prater (formerly Prater Pulverizer) developed was a hammer mill, and since that time our company has sold thousands of hammer mills to customers in various industries. For over 90 years, we have relied on advanced technology to properly engineer our mills for new applications. Prater continues to provide solutions for some of the most demanding processing challenges with our innovative designs, industry expertise, and advancements that provide a shorter wait for your business return on investment. Our hammer mills are commonly used for many different particle reduction applications, including those that require high capacities, extreme power efficiency, and uniform particle size.

With a Prater hammer mill, you can increase the mills throughput capacity without having to increase its power requirements. Companies both large and small rely on Prater for efficient milling solutions and proven expertise.

Prater hammer mills are the premier choice for applications requiring high capacities, operational efficiency, and uniform particle size distributions. All five Prater Full-Screen hammer mills are equipped with our proprietary Full-Screen design that enhances end-product quality while simultaneously extending unit lifespan. Major applications include:

The Prater Full-Screen Hammer Mill utilizes a specially shaped grinding chamber designed with distinct grind-and-release zones. Coarse raw product is fed into the chamber, using a rotary feeder or screw, by way of a product inlet at the top of the unit. High-speed hammers impact coarse material against stationary cutting plates fixed to the top of the pre-grind chamber. Impact with the cutting plates decreases the velocity of the material and guides it into the hammer path for maximum impact speed differential. Screen-to-hammer clearance is minimized at the 3 oclock and 9 oclock positions to amplify impact.As material moves toward the bottom of the chamber, hammer-to-screen clearance increases toward the 6 oclock position to help with deceleration and egress of fully conditioned particles through the sizing screen. An adjustable diverter system prevents unfinished product from re-entering the inlet and product feed stream. Finished product is discharged via a hopper below the mill where a mechanical conveyor or pneumatic system can be utilized to remove the ground material. Prater provides a full inventory of hammers, screens, and other grinding elements that are available to satisfy almost any grinding application.

Prater stands ready to serve your needs. If your application requires a custom build, our staff will tailor a solution. Similarly, if you already own a Prater mill that requires parts, service or an upgrade, please contact us for a free consultation.

working principal, types and application of hammer mills - j&m industrial blog

Hammer mills are whole purpose machines that are designed to crush, grind, and mill material. As the name suggests, the purpose is served by grinding material by small hammer blows. The history of hammer mills is quite old, as the first invention was made in 488 AD. Hammer mills are used for material processing in the food, construction, chemical, and cosmetic industries. This post gives insights about working, types, and industrial applications of hammer mills.

The operation of a hammer mill is simple. It has a cylindrical steel drum inside which hammers are mounted on a horizontal or vertical shaft. These hammers freely rotate around their axis. The material is fed in the drum, which when rotating causes the hammers to blow on the fed material. The ground material is shredded and made to pass through the screens of desired sizes, which are placed inside the drum. There are screenless hammer mills, which use air to separate large and small-sized particles.

These hammer mills serve as primary, secondary, or tertiary material crushers. The size and power capacity of hammer mills vary according to the application. The industrial hammer mills use the electric motors of power over 2000 to 5000 horsepower.

Farm grain machines, sawmills, plastic grain milling, shredding paper, automobile shredding machine, are some of the excellent examples of hammer mills. Although the specific hammer mills applications in different industries are as follows:

The quality of a reduced product depends on the quality of the hammer mill, so it is important that you choose good quality hammer mills from recognized suppliers. Many times, used hammer mills are also equally good as new ones. J&M Industrial is a prominent supplier of Used and Surplus Size Reduction Equipment and related products. These used hammer mills are sourced from brands like Dresser Industries, Bliss Industries, and so on. They are available in different configurations and price ranges to meet your application requirements.

hammer mills for grain milling or recycling wood & paper shredding

Hammer mills are used to crush or to shred various types of aggregate into smaller particles. They are used in a variety of industries for a number of specific applications. They can be powered electrically or by diesel engines, and the environments in which they operate can be as small as a portion of one room to the size of an entire room. Common applications for the larger machines include, but are not limited, the following: Breaking up corn in ethanol plants Grinding grain into flour to feed to livestock Creating pulp for fruit juice production Recycling wood into mulch Grain milling operations Turning scrap wood into fuel for boilers In addition to the large hammer mills described above, there are also many smaller devices that are often categorized as desktop models. Applications for these machines include: Paper shredding Automotive scrap shredding Mulching yard waste for compost Pulverizing large rocks Waste pulverizing for landfills or recycling operations As varied as these applications are, all hammer mills feature the same basic design. A steel drum houses an assembly where a rotating shaft is mounted either vertically or horizontally. Along the shaft, a series of hammers is mounted in such a manner as to allow each one to swing freely around the shaft. As the rotor begins to spin at high RPMs, the hammers pick up centrifugal force. This centrifugal energy magnifies the force of each individual blow. The collective impact that this brings to bear upon the raw material provides the necessary force to break it into smaller pieces, shred it into scrap, or grind it completely into powder. One could describe the operation of any such machine in four simple steps that are common to all sizes, lines, and models within this category of devices. 1. The material is fed into the rotating drum 2. The pulverizing assembly breaks this raw material down into the desired form. 3. The material components are then screened. 4. Pieces that meet criteria are discharged from the machine. Pieces that require further pulverization are then fed back through the machine. The simplicity of the process allows hammer mills to be customized to perform any type of crushing, shredding, or pulverizing operations. One of the most essential design categories includes devices that reduce medium particles to fine particles. This has both industrial and food processing applications. For some specific food processing applications, even more specialized devices are used to produce ultra fine grinding of high capacity volume feeds of raw materials. This is vital to many food processing applications, particularly those outputting meal or flour. Some models feature pneumatic conveyers and filtered ventilation that removes dust from the raw materials. In many facilities, this is essential to preventing explosions that can result from too many airborne particulates building up in the air. By minimizing the amount of these particulates, industrial and shipping facilities can maintain a cleaner and healthier working environment for their employees. Many small hammer mills can be powered from a standard 120V wall socket. Some of the largest models operate at up to 2,000 horsepower. These require diesel engines for power.

7 important applications of hammer mills you should know - saintytec

This article focuses on key applications of hammer mills in various industries such as pharmaceutical, food processing, cosmetic or chemical industries. In all these industries, the principle of operation depends its ability to crush materials into smaller pieces.

For instance, hammer mills grind coffee and soya for making beverages in food processing industries. Furthermore, it is also a common practice in the cosmetic industry where a number of nuts are ground to mate body lotions and creams.

Furthermore, small particles will ensure there is an even distribution of particles in the final formulation. Therefore, a hammer milling machine will ensure consistency in particle distribution, producing a quality mixture.

As this equipment mills or reduces the average size of materials, it does the mixing at the same time. This results in a final product with smaller particles whole ingredients are evenly distributed within the content.

These 7 applications of hammer mill are clear indications that this equipment plays an integral role in the various manufacturing processes. However, to benefit more from a hammer mill, you need a high quality and reliable equipment that conforms to all quality standards and specifications.

Hey , I am Tony , General manager of Saintyco and expert in pharmaceutical equipment industry for over 20 years, I would like to share my experience in the field.Saintyco is a leading pharmaceutical machinery manufacturer ,We can provide you one stop solution for all your pharmaceutical equipment requirement.If any questions, freely to reach me,I will try my best to give you good advice and solution.

the working principle of hammer mills (step-by-step guide)

SaintyCo hammer mills are high precision machines for grinding solid and hard granules. Our hammer mills guarantee uniform grinding, noiseless operation and less heat buildup in all pharmaceutical processes.

Whether you need standard or customized hammer mills, SaintyCo offers many series for specialized shredding applications. The cGMP compliance and innovative design make SaintyCo hammer mills the most sough-after in this industry.

Every part/component you see in the image above plays an integral role in the overall working principle of hammer mills. However, the milling process mainly takes place in the crushing chamber (part 3).

Hammer mills crushing tools may be coupled directly to a motor or driven by a belt. As opposed to direct connection, the belts can cushion the motor from shock and allows for accurate speed adjustment.

In case youre new to hammer mills in pharmaceutical and food processing industries, here are three crucial steps that will help you understand how this equipment works. Before that, you can watch this video to see how hammer mills work:

Basically, within this chamber, the material is hit by a repeated combination of knives/hammer impact and collision with the wall of the milling chamber. Moreover, collision between particles to particles play an instrumental role in this size reduction process.

In most cases, the mechanical process of reducing large size particles into small particle may result in a fine or coarse finish. How is then is this possible when you use the same pharmaceutical hammer mill equipment?

hammer mill operating principle

Operational Characteristics:The method of operation has a considerable effect upon the nature of the product. When minimum fines are a requirement, the hammer mill should always he operated in closed circuit with a screen, or screens; the circulating load should be fairly high; speed should be as low as is consistent with physical structure of the material; and grates should be widely spaced or, in some cases, dispensed with entirely.

Although the hammer mill usually produces a relatively high percentage of fine material, it does not usually make an inordinately high proportion of what are commonly designated as extreme-fines unless the mill is adjusted and operated with that end in view. For example, if we are turning out a 0.75 (top size) product in one of these machines we will usually find the proportion of particles in the range between 0.25 and about 30 or 40 mesh to be high, as compared to the product of pressure-type crushers; but unless the material is very friable and the natural grain size very fine the percentage of minus 100- and 200-mesh particles will usually compare quite closely. Here again we have the fact that the impact effect falls off directly with the particle mass, to explain an apparent inconsistency.

It is easy to understand why the hammermill should turn out a cubical product. The impact action is ideally adapted for breaking flat or elongated spalls. If the material contains numerous parallel cleavage planes the initial blows delivered by the hammers may knock off flat spalls; but the chances are very much against such spalls getting out of the machine before they are struck several times and broken into particles of more cubical proportions.

This is especially true of machines which have a long impact zone ahead of the grate section, as no particle can possibly be discharged until it has passed through this impact section, where it will almost certainly be struck several blows.

Hammermills are capable of accomplishing: reductions very muchgreater than any other type of crushing equipment. It is possible, though not always economical, to make reductions as high as 20:1 in open circuit, and to double this performance in closed circuit. As in any other type of crusher, low reduction ratios are indicated where a low percentage of fines is desirable.

Time was when all hammermills came under the generic title of pulverizer which was quite appropriate as it aptly described the kind of work to which they were, in those days, almost exclusively applied. This duty consisted largely of such work as pulverizing limestone for various purposes: agricultural flour, glasssand, tube mill feed, and so forth. This was work for which the hammermill was and still pre-eminently well suited, and large numbers of them are used today for such service. The field has however in recent years been greatly expanded. The following list, while not comprehensive, includes some of the more important present day applications:

Not all of the uses listed can, in our opinion, be considered as economically sound applications for the hammermill. This machine cannot be expected to operate economically on abrasive feed, and it should not be so applied unless there are strong reasons for doing so. Generally this narrows itself down to cases where no other type of crusher will deliver the type of product required; occasionally the high reduction ratio of which they are capable will dictate their use in temporary jobs where the cost of a two-stage set-up of more economical operating characteristics would more than offset the cost of the single hammermill plus the expected cost of maintenance. A case in point to illustrate the latter condition is that of pilot plant testing in the development of new mining properties.

Sectional view shows how material is broken down in one type of hammermill. Material is fed to an inclined plate which is fastened to the hopper over the feed opening. This plate is so arranged that the material is evenly distributed and fed uniformly to the mill. The rapidly revolving hammers (see arrows indicating direction of rotation) strike the material a succession of heavy blows, shattering it and throwing it violently against the first involute breaker plate. Striking this plate with great farce, the material is again shattered and, as it rebounds, it is struck again and carried ta a second involute breaker plate from where it again rebounds and so on through five stages. The pulverized product passes out through grate bars In the bottom of the machine

We have never subscribed to the idea that the hammermill is suited to the primary breaking of shovel-loaded, quarry-run, or ROM mine-run rock and ore. Even though the material be non-abrasive and quite friable there are other machines which are better fitted for such work. Nor do we believe that the hammermill has a place in any of the stages of a plant intended for the production of commercial crushed stone unless the production of a high percentage of fines is not objectionable; a rather rare condition for operations of this character. These legitimate restrictions still leave quite a broad field for this ma-chine, and it is probable that more applications will crop up from time to time as our chemical industries grow.

Examination of cement plant flowsheets, discloses that, at that time, only six of these plants employed hammermills, and two of these were used in the shale crushing department. Today the hammermill is widely accepted as a secondary or tertiary crusher in cement plants throughout the country; and there are isolated instances where they perform the primary breaking as well.

The Pulverator/Impactor/Hammermill/Impact-Crusher was successfully applied to the production of manufactured sand for concrete aggregates used in the construction of a large dam in one of the eastern states. This application was made after crushing rolls had been tried and discarded because their product ran so heavily to flat spalls that a workable concrete could not be made with it. We mention this case as being indicative of the ability of the hammermill to cube material, even though the rocks physical structure is conducive to spalling or flaking. Subsequent installations for the same purpose have been equally successful.

The Dixie (Non-Clog) Hammer Mill Crusher differs from all other hammermills in that its breaker plate, instead of being stationary, is a continuously moving belt of manganese steel links. The feed thrown into the hopper is carried by a positive mechanical feed to the hammer-points and then on through the grates.

The most important results from the installation of the Dixie (Non-Clog) Hammermill are the uniform high quality of the product and the enormous crushing power, which, with reduction range of this mill, eliminate the necessity of using several units to obtain the necessary production.

The Dixie (Non-Clog) Hammermill is manufactured in fourteen different sizes, adapted to reduction of any materials containing moisture without clogging. Due to various adjustments this equipment is capable of crushing to a minimum of fines or pulverizing to a maximum of fines. The adjusting features are exclusive Dixie patents.

The non-clog moving breaker plate is a patented feature found only in Dixie Hammermills, positively eliminating all troubles and loss of production from wet or sticky materials that would continually clog any other type crusher or pulverizer. It is capable of crushing potash, salt, mica, limestone, gypsum, coal, or any similar soft material not exceeding 4 on the Mohs scale of hardness.

The Jeffrey Miracle Hammer Crusher is designed for the reduction of large pieces and large capacities of limestone, shale, slag, and cement rock. The larger sizes are built to take steam shovel size limestone, crushing it into pieces 1, 2, 3, or 4 and under, in one operation, the one unit doing the work ordinarily done by two or more of other types of crushers. This enables large reduction of limestone and other materials to a uniform size with minimum initial and production costs. All parts are extra heavy to withstand heavy, continuous service. The Miracle Hammer Crushers are supplied with either heavy cast iron frames or with armor-plate steel frames with manganese steel liners. These crushers are provided with a hinged breaker plate easily adjustable to compensate for wear, as well as giving easy access to working parts. The large, heavy duty crushers are frequently used in such industries as carbide, chemical and cement as a primary machine where large capacities and cubical products are desired.

The Jeffrey Heavy Duty Reversible Hammer Crusher is designed especially for reducing bituminous coal down to a product of 85% minus 1/8, at large capacities, for coking purposes. These machines are also adaptable to the reduction of abrasive materials since they are symmetrical about the vertical center line and when one corner of the hammers become worn, it is only necessary to reverse the direction of the rotor in order to use the opposite unused faces of the hammers. The frame is made of heavy welded plate steel equipped with removable manganese liners and provided with vertical hinged breaker plates to compensate for the wear on breaker plate liners.
