iron ore fines sand washing machine equipment

silica sand processing & sand washing plant equipment

Silica sand low in iron is much in demand for glass, ceramic and pottery use, and for many of these applications clean, white sand is desired. Impurities such as clay slime, iron stain, and heavy minerals including iron oxides, garnet, chromite, zircon, and other accessory minerals must not be present. Chromium, for example, must not be present, even in extremely small amounts, in order for the sand to be acceptable to certain markets. Feldspars and mica are also objectionable. Generally, iron content must be reduced to 0.030% Fe2O3 or less.

Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than 0.03% Fe2O3. Concentrating tables will remove free iron particles but iron stained and middling particles escape gravity methods. Flotation has been very successfully applied in the industry for making very low iron glass sand suitable even for optical requirements.Sub-A Flotation Machines are extensively used in this industry for they give the selectivity desired and are constructed to withstand the corrosive pulp conditions normally encountered (acid circuits) and also the abrasive action of the coarse, granular, slime free washed sand.

The flowsheet illustrates the more common methods of sand beneficiation. Silica may be obtained from sandstone, dry sand deposits and wet sand deposits. Special materials handling methods are applicable in each case.

The silica bearing sandstone must be mined or quarried much in the manner for handling hard rock. The mined ore is reduced by a Jaw Crusher to about 1 size for the average small tonnage operation. For larger scale operations two-stage crushing is advisable.

The crushed ore is reduced to natural sand grain size by Rod Milling. Generally, one pass treatment through the Rod Mill is sufficient. Grinding is done wet at dilutions in excess of normal grinding practice. A Spiral Screen fitted to the mill discharge removes the plus 20 mesh oversize which either goes to waste or is conveyed back to the mill feed for retreatment.

Sand from such deposits is generally loaded into trucks and transported dry to the mill receiving bin. It is then fed on to a vibrating screen with sufficient water to wash the sand through the 20 mesh stainless screen cloth. Water sprays further wash the oversize which goes to waste or for other use. The minus 20 mesh is the product going to further treatment.

The sand and water slurry for one of the three fore-mentioned methods is classified or dewatered. This may be conveniently done by cyclones or by mechanical dewatering classifiers such as the drag, screw, or rake classifiers.

From classification the sand, at 70 to 75% solids, is introduced into a Attrition Scrubber for removal of surface stain from the sand grains. This is done by actual rubbing of the wet sand grains, one against another, in an intensely agitated high density pulp. Most of the work is done among the sand grains not against the rotating propellers.

For this service rubber covered turbine type propellers of special design and pitch are used. Peripheral speed is relatively low, but it is necessary to introduce sufficient power to keep the entire mass in violent movement without any lost motion or splash. The degree of surface filming and iron oxide stain will determine the retention time required in the Scrubber.

The scrubbed sand from the Attrition Machine is diluted with water to 25-30% solids and pumped to a second set of cyclones for further desliming and removal of slimes released in the scrubber. In some cases the sand at this point is down to the required iron oxide specifications by scrubbing only. In this case, the cyclone or classifier sand product becomes final product.

Deslimed sand containing mica, feldspar, and iron bearing heavy minerals can be successfully cleaned to specifications by Sub-A Flotation. Generally this is done in an acid pulp circuit. Conditioning with H2SO4 and iron promoting reagents is most effective at high density, 70-75% solids. To minimize conditioning and assure proper reagentizing a two-stage Heavy Duty Open Conditioner with Rubber Covered Turbine Propellers is used. This unit has two tanks and mechanisms driven from one motor.

The conditioned pulp is diluted with water to 25-30% solids and fed to a Sub-A Flotation Machine especially designed for handling the abrasive, slime free sand. Acid proof construction in most cases is necessary as the pulps may be corrosive from the presence of sulfuric acid. A pH of 2.5-3.0 is common. Wood construction with molded rubber and 304 or 316 stainless steel are the usual materials of construction. In the flotation step the impurity minerals are floated off in a froth product which is diverted to waste. The clean, contaminent-free silica sand discharges from the end of the machine.

The flotation tailing product at 25 to 30% solids contains the clean silica sand. A SRL Pump delivers it to a Dewatering Classifier for final dewatering. A mechanical classifier is generally preferable for this step as the sand can be dewatered down to 15 to 20% moisture content for belt conveying to stock pile or drainage bins. In some cases the sand is pumped directly to drainage bins but in such cases it would be preferable to place a cyclone in the circuit to eliminate the bulk of the water. Sand filters of top feed or horizontal pan design may also be used for more complete water removal on a continuous basis.

Dry grinding to minus 100 or minus 200 mesh is done in Mills with silica or ceramic lining and using flint pebbles or high density ceramic or porcelain balls. This avoids any iron contamination from the grinding media.

In some cases it may be necessary to place high intensity magnetic separators in the circuit ahead of the grinding mill to remove last traces of iron which may escape removal in the wet treatment scrubbing and flotation steps. Iron scale and foreign iron particles are also removed by the magnetic separator.

In general most silica sands can be beneficiated to acceptable specifications by the flowsheet illustrated. Reagent cost for flotation is low, being in the order of 5 to 10 cents per ton of sand treated. If feldspars and mica must also be removed, reagent costs may approach a maximum of 50 cents per ton.

Laboratory test work is advisable to determine the exact treatment steps necessary. Often, attrition scrubbing and desliming will produce very low iron silica sand suitable for the glass trade. Complete batch and pilot plant test facilities are available to test your sand and determine the exact size of equipment required and the most economical reagent combinations.

Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than 0.03% Fe2O3. Concentrating tables will remove free iron particles but iron stained and middling particles escape gravity methods. Flotation has been very successfully applied in the industry for making very low iron glass sand suitable even for optical requirements.

Sub-A Flotation Machines are extensively used in this industry for they give the selectivity desired and are constructed to withstand the corrosive pulp conditions normally encountered (acid circuits) and also the abrasive action of the coarse, granular, slime free washed sand.

The flowsheet illustrated is typical for production of glasssand by flotation. Generally large tonnages are treated, forexample, 30 to 60 tons per hour. Most sand deposits can be handled by means of a dredge and the sand pumped to the treatment plant. Sandstone deposits are also being treated and may require elaborate mining methods, aerial tramways, crushers, and wet grinding. Rod Mills with grate discharges serve for wet grinding to reduce the crushed sandstone to the particle size before the sand grains were cementedtogether in the deposit. Rod milling is replacing the older conventional grinding systems such as edge runner wet mills or Chilean type mills.

Silica sand pumped from the pit is passed over a screen, either stationary, revolving or vibrating type, to remove tramp oversize. The screen undersize is washed and dewatered generally in a spiral type classifier. Sometimes cone, centrifugal and rake type classifiers may also be used for this service. To clean the sand grains it may be necessary to thoroughly scrub the sand in a heavy-duty sand scrubber similar to the Heavy-duty Agitator used for foundry sand scrubbing. This unit is placed ahead of the washing and dewatering step when required. The overflow from the classifier containing the excess water and slimes is considered a waste product. Thickening of the wastes for water reclamation and tailings disposal in some areas may be necessary.

The washed and dewatered sand from the spiral-type classifier is conveyed to a storage bin ahead of the flotation section. It is very important to provide a steady feed to flotation as dilution, reagents and time control determines the efficiency of the process.

Feeding wet sand out of a storage bin at a uniform rate presents a materials handling problem. In some cases the sand can be uniformly fed by means of a belt or vibrating-type feeder. Vibrators on the storage bin may also be necessary to insure uniform movement of the sand to the feeder. In some cases the wet sand is removed from the bin by hydraulic means and pumped to a spiral-type classifier for further dewatering before being conveyed to the next step in the flowsheet.

Conditioning of the sand with reagents is the most critical step in the process. Generally, for greater efficiency, it is necessary to condition at maximum density. It is for this reason the sand must be delivered to the agitators or conditioners with a minimum amount of moisture. High density conditioning at 70 to 75% solids is usually necessary for efficient reagentizing of the impurity minerals so they will float readily when introduced into the flotation machine.

The Heavy-duty Duplex Open-type Conditioner previously developed for phosphate, feldspar, ilmenite, and other non-metallic mineral flotation is ideal for this application. A duplex unit is necessary to provide the proper contact time. Circular wood tanks are used to withstand the acid pulp conditions and the conditioner shafts and propellers are rubber covered for both the abrasive and corrosive action of the sand and reagents.

Reagents are added to the conditioners, part to the first and the balance to the second tank of the duplex unit, generally for flotation of impurities from silica sand. These reagents are fuel oil, sulphuric acid, pine oil, and a petroleum sulfonate. This is on the basis that the impurities are primarily oxides. If iron is present in sulphide form, then a xanthate reagent is necessary to properly activate and float it. The pulp is usually regulated with sulfuric acid to give a pH of 2.5-3.0 for best results through flotation.

A low reagent cost is necessary because of the low value of the clean sand product. It is also necessary to select a combination of reagents which will float a minimum amount of sand in the impurity product. It is desirable to keep the weight recovery in the clean sand product over 95%. Fatty acid reagents and some of the amines have a tendency to float too much of the sand along with the impurities and are therefore usually avoided.

After proper reagentizing at 70 to 75% solids the pulp is diluted to 25 to 30% solids and introduced into the flotation machine for removal of impurities in the froth product. Thepulp is acid, pH 2 .5 to 3.0 and the sand, being granular and slime free, is rapid settling so a definite handling problem is encountered through flotation.

The Sub-A Flotation Machine has been very successful for silica sand flotation because it will efficiently handle the fast settling sand and move it along from cell to cell positively. Aeration, agitation and selectivity due to the quiet upper zone can be carefully regulated to produce the desired separation. The machine is constructed with a wood tank and molded rubber wearing parts to withstand the corrosive action of the acid pulp. Molded rubber conical-type impellers are preferred for this service when handling a coarse, granular, abrasive sand.

Flotation contact time for removal of impurities is usually short. A 4, and preferably a 6 cell, machine is advisable. Cell to cell pulp level control is also desirable. A 6 cell No. 24 (43 x 43) Sub-A Flotation Machine in most cases is adequate for handling 25 to 30 tons of sand per hour. If the impurities are in sulphide form a standard machine with steel tank and molded rubber parts is adequate provided the pulp is not acid. Otherwise acid proof construction is essential.

The flotation tailing product is the clean sand discharging from the end of the flotation machine at 25 to 30% solids and must be dewatered before further processing. Dewatering can be accomplished in a dewatering classifier and then sent to storage or drying. Top feed or horizontal vacuum filters are often used to remove moisture ahead of the dryer. Dry grinding of the sand to meet market requirements for ceramic and pottery use is also a part of the flowsheet in certain cases.

This particular sand was all minus 20 mesh with only a trace minus 200 mesh and 70% plus 65 mesh. Iron impurity was present as oxide and stained silica grains. The plant which was installed as a result of this test work is consistently making over a 95% weight recovery and a product with not over 0.02% Fe2O3 which at times goes as low as 0.01% Fe2O3.

Si02, minimum..99.8 per cent Al2O3, maximum..0.1 percent Fe2O3, maximum..0.02 per cent CaO + MgO, maximum.0.1 percent For certain markets, a maximum of 0.030 per cent Fe2O3 is acceptable.

Natural silica-sand deposits generally contain impurityminerals such as clay, mica, and iron oxide and heavy iron minerals which are not sufficiently removed by washing and gravity concentration. Flotation is often used to remove these impurity minerals to meet market specifications.

Anionic-type reagents, such as fatty acids, are used to float some impurities in alkaline pulp. Cationic-type reagents such as amines or amine acetates are also used with inhibitors such as sulphuric or hydrofluoric acids to float certain impurity minerals and depress the silica.

After silica sand washed by a beneficiation plant, it can meets the industry standards. Artificial sand and natural sand contain certain impurities. It is necessary to use thequartz sand washing plant to clean the impurities in the prepared sand to complete various construction requirements. The quartz sand washing equipment has been exported to Saudi Arabia, Thailand, Malaysia, South Africa, Australia, Europe, etc.

Washing sand recycling machine working principle. After the natural silica sand is classified and filtered by the screening equipment, the qualified products flow into the spiral sand washing machine through the launder or the pipeline. It is fully cleaned, soaked and broken by a screw mixer (for larger muddy and extra-large effect), sandstone is fully separated from impurities and mud.

Fine sand and muddy water are deposited in the tail of the spiral washing, and the recovery of fine sand is achieved through a concentration and recovery device. Then the coarse and fine sand enters the wheel washing machine at the same time for secondary cleaning to achieve complete separation of the sediment.

Scrub With the help of mechanical force and the grinding and peeling force between the sand grains, the thin film iron, adhesive and muddy impurity minerals on the surface of the silica sand are removed, and the unconstituted mineral aggregates are further smashed, and then the classification operation is performed to further purification.

Pickling If the finished sand has a high iron content, it will enter the pickling process. First, it will be washed to remove powder and impurities, and then pickled, soaked and washed, dried or cooled.

Magnetic separation is mainly used to remove magnetic minerals in silica sand. For example, weak magnetic minerals such as hematite, limonite, and biotite can be removed by a strong magnetic machine, while strong magnetic minerals such as magnetite can be subjected to weak magnetic separation. Machine removed. Flotation is used to remove some impurities that cannot be removed by magnetic separation, such as feldspar and mica in silica sand, to further improve its purity.

Then the coarse sand is lifted into the high-frequency dewatering sieve feed end by the impeller of the wheel washing machine, and the overflow mud water flows into the high-frequency dewatering sieve water tank through the pipeline and then is recycled into the high-frequency dewatering sieve through the concentration and separation device. The vibration of the sieve is dehydrated, and finally, the sandstone is cleaned, recovered, dehydrated and discharged.

The environment protection sand washing production line is a system solution for the problems of sand dewatering, tailwater purification, waste dry discharge.

fine material screw washers | mclanahan

Fine Material Screw Washers wash, classify and dewater -10mm or 3/8 solids material in one machine. They often accept feed slurry from Wash Screens, Sand Classifying Tanks, Hydrocyclones, Hydrosizers and other Fine Material Screw Washers. If an application calls for a greater level of dewatering, they are often placed in series with a Dewatering Screen.

Fine Material Screw Washers are especially simple for operations looking to wash dry screened fines. When compared to other sand washing systems, Screw Washers are a low-capital cost and low electric power user machine. They are widely used by construction sand producers, mining companies, solar salt/brine processors and glass recycling plants.

McLanahan offers an extensive range of sizes of Fine Material Screw Washers. Sizing and selection is based on several factors, including the type of feed solids, feed gradation, desired product specification, capacity required and volume of the feed slurry. It is extremely important that all of these factors are taken into consideration when selecting the proper size of screw washer. Poor design and planning can lead to overflow of desired fine material, resulting in lost product and profit. McLanahan Corporations utilizes its vast experience in washing and classifying equipment to ensure proper machine size by reviewing application data that includes slurry volume and your feed gradation data of water coming in with the feed.

Sometimes when processing a very dilute sand slurry, such as at a stone rinsing vibrating screen station, and needing to retain +200 mesh or 75 micron solids, a sand screw size selection may need to be larger than what appears to be required when the solids feed rate isnt that much. If you look at a manufacturers tons per hour data, a machines water volume capacity may not meet your needs for fine sand solids retention based on the water volume capacity chart.

McLanahan Corporation offers a wider range of Fine Material Sand Screws than other manufacturers. High Water Volume Screw Washers are available sizes that allow the mixing and matching of a screw shaft size to handle a reduced capacity of sand solids with a washer box tub to handle a larger than normal water volume. This provides a lower cost option as compared to a larger standard sand screw. If the sand capacity is 50 tph with 1,000 gallons per minute of water, a 36 diameter screw shaft can be provided in a 54 washer box tub.

High Water Volume Screw Washers have been in operation since 2002, providing operators a proper alternative with increased product sized sand fines retention, as opposed to a standard machine selected incorrectly for just the tons per hour sand solids capacity.

To achieve the desired results with a Fine Material Screw Washer, sand or other fine material is directed to the feed box in the baffle plate. Coarse, heavier materials settle to the bottom of the box, while ultra-fine waste fractions are carried by the up-current of water to the surface and overflow the weirs.

Heavier material that settles to the bottom is conveyed up an 18-degree slope toward the discharge end. The rolling and tumbling of the material releases fines and some lightweight fractions into suspension. It also mildly scrubs superficial clays from the sand/mineral surfaces. As the material is conveyed toward the discharge end, the water begins to separate from the material. A channel in the washer box/tub is provided opposite the conveying side to allow water to drain from the solids and overflow the weirs.

In order to properly retain material in a screw washer, a calm pool area must be maintained. The feed box within the baffle plate is used to direct material away from the calm pool area; however, if the pool area is turbulent, finer material that may be desirable in the final product will overflow the weirs. The baffle plate helps to separate the washer box feed area and keep the pool area calm. In some applications, producers may remove the baffle plate and feed the material close to the back plate of the weir to help agitate the pool area and overflow undesirable material.

The speed of the Fine Material Screw Washer is determined by the percent passing 50 mesh in the desired product. If the screw washer is running too fast, material does not have a chance to stay on the flight long enough to dewater. The material will fall off of the flight and return to the pool area, leading the box to eventually fill with sand and stall the screw shaft.

Fine Material Screw Washers are widely used to wash and dewater: alluvial/natural sands, manufactured/crushed sands, frac sands, industrial/silica sands, iron ore fines, fine phosphate solids, solar evaporated salt solids and crushed glass.

Hydrocyclones, Dewatering Screen systems using a Hydrocyclone, and bucket wheels. Youll find that for the cost and low kW (hp) requirements, a Fine Material Screw Washer will be an extremely viable option and a good choice for you.

Functioning to wash, dewater and classify all solids material all in one machine, McLanahan Fine Material Screw Washers are ideal for construction sand producers, mining companies, salt/brine reclamation and glass recycling. Fine Material Screw Washers create a drier product discharge, while preventing water and even the smallest particles from reaching the bearing thanks to the McLanahan Twin-Seal Pak submerged rear bearings.

The raw material is fed through a vibrating feeder, on the one hand sieving small pieces of weathered stone and soil, on the other hand feeding large pieces of stone into coarse crushing equipment. After coarse crushing, it enters the medium crushing equipment and then passes through the vibration to feed the screening. Recycle Processing of crushing equipment in return of a large stone. According to the actual needs, a part of a 40-80mm block finished aggregate can be produced. The stone which meets the requirement of feeding size of vertical impact sander enters the sander to be broken and shaped. After examination and screening, it is divided into the sand and small aggregate in various finished products.

According to the need, the screening equipment can be divided into a variety of finished aggregate proportions. Part of the return to the sand making machine cycle crushing. Finally, high-quality artificial sand is obtained by using a powder separator. Adopts high-efficiency dust remover dust, low cost, and solves the problem of dust pollution in dry process sand making plant and the content of sandstone powder exceeding the standard. The recovered stone powder can be used to make bricks, etc.

Disadvantage: 1. Dust content is large, easy to cause air pollution. 2. The requirement of raw materials is high, and the content of impurities such as soil and organic matter in sand and stone should be strictly controlled.

Wet sand making is a sand making process + sand washing process. Rounded to the appearance of sand grains and reduced soil content, this process is suitable for water-rich areas, close to water sources. It can establish a sedimentation tank to achieve water recycling, but also can add the fine sand recovery machine to collect the fine sand in the wastewater.

The front process of wet sand-making is the same as that of dry sand-making. except that the finished sand is washed by a spiral or wheel washing machine. The wastewater and washed sand can be recycled in the fine sand recovery unit according to the actual situation.

Disadvantage: 1. Needs a large amount of water resource in the wet sand making process, and the cost is high. 2. Limited by environmental geography, the region's water resources can not be used if not enough.

Wet sand-making is the mode of the sand washing machine, which can reduce the soil content of machine-made sand, the appearance of sand is round and the quality is beautiful. Dry Sand making is a mode of using powder separator, which can realize the separation of sand and powder. Select high-quality sand suitable for building sand.

Wet sand making plant is suitable for areas with rich water resources and close to the water source. And can also establish a sedimentation tank, water resources to achieve recycling. The dry sand-making process is not limited by the environment, and it can also be realized in areas where water resources are scarce.
