bauxite - ore crushing solutions - dsmac

Bauxite mine is actually kind of ore minerals collectively formed mainly by gibbsite, a boehmite or a diaspore which can be used in the industry. Bauxite mine can be used widely in many industries among which the most important is to be used for refining aluminum in aluminum Industry, refractory and abrasive materials, and raw materials for high alumina cement. The quality requirements to bauxite mining vary according to their different applications.

The general process of extracting aluminum in industry is as follows: First you need to extract alumina from bauxite. Then the alumina will be changed to aluminum by electrolysis. Now there are mainly three methods for alumina production which include sintering, Bayer and joint method.

However, there is a very important procedure before extracting aluminum from bauxite mine that is bauxite crushing and bauxite grinding. Generally we choose DSMAC crusher or DSMAC grinding mill to crush the raw materials to be required fineness before used to produce aluminum. Bauxite crushing is relatively simple. Generally we use the professional DSMAC mining equipments for bauxite crushing. As the leading stone crusher manufacturer and grinding mill manufacturer, DSMAC has also been closely following the bauxite mining at home and abroad. DSMAC has manufactured large amount of mining equipments to global countries, such as jaw crusher series, impact crusher series, cone crusher series and the grinding mill series, etc. DSMAC mining equipments have been exported to more than 130 countries which are widely applied in mining industry including the bauxite crushing. For decades, DSMAC has always continued to innovate in the development, production, sales, and service sectors. Rich experience and high-tech applications help our products maximize customers satisfaction.

As the important resource of nowadays industry production, ore minerals are required nearly in every business in the industry. Together with the professional crushing, grinding and screening technology of world class, DSMAC supply professional ore mineral processing equipments including Metal Ore MineralsNon Metallic Minerals crushing plants, grinding equipments, screening machines and feeding machines.

bauxite crushing & phosphate rock processing

bauxite crushing & phosphate rock processing

Three Reversible Impactors are located at the Piney Point Plant, Palmetto, Florida. This plant is part of the Davison Chemical Division of Borden Chemical Co. These machines reduce diammonium phosphate or granular triple superphosphate (GTSP) from a feed of 75 x 3.35mm (3 x 6 mesh) to an 852-952 minus 3.35mm (6 mesh) product. Capacity is 41 TPH (45 STPH) with 75 KW (100 HP) V-belt drive.

Single Roll Crushers are installed at the White Springs, Florida Plant of Occidental Chemical Co. The materials crushed are triple superphosphate and diammonium phosphate. The feed is 600 x 450 x 150mm (24 x 18 x 6) and product is 37.5mm (1.5). Capacities are 27-36 TPH (30-40 STPH). The relatively slow speed of 7.3 rad/s (70 RPM) assures long wear of the staggered tooth configuration. The proper tooth configuration assures that product top size will be quite uniform.

A Twin Rotor Impactor is installed at the Nichols, Florida Plant of International Minerals and Chemical Co. This is a machine equipped with two parallel rotor assemblies with opposite rotation so that material must pass in a narrow gap between the respective hammer circles.

There is no basic formula to determine Breaker capacity because of the many variables which must be considered including type of material, feed size, gradation of feed, and desired product size. Breaker size is based principally on a determination of the volume to be screened and the volume to be reduced in size.

An unusual crusher application utilizes a One-Way Hammarmill Installed at Companhia Mineira de Aluminio, San Paulo, Brazil. The feed is 300mm (12) maximum with a large portion being minus 150mm (6) . The feed is mine-run bauxite to which is added a caustic sodium aluminate solution to give a moisture level of 20 to 30%.

In the modern mining processing line, bauxite is an important raw-material which is used to produce aluminum.Bauxite can be widely used in many industries, among which the most important is to be used to refining aluminum, working as refractory and abrasive materials, and raw materials for high alumina cement. But it is always found near the surface, so we need surface mining equipments. Bauxite crusher machine is one of the most important surface mining equipment in bauxite crushing plant.

In order to facilitate the exploitation of the ore, we has developed a variety of bauxite crusher,which using an advanced hydraulic power system, greatly improved work efficiency, saving investment costs, and also reduces the human waste, at the same time the operation more simple and convenient. Here are listed two kinds of bauxite crushing plant:

But do you know how does the crusher work in the bauxite crushing plant? Bauxite crusher is used to break the big size mineral ore down to a smaller size suitable for transporting along the conveyor belt to the refineries. The crushing plant is made up of a number of components that include vibrating screen, stone crushing machine and grinder. Fine material drops through the vibrating screen while larger material passes over the screen to the crusher that breaks up the large rocks. The material that passes through the vibrating screen is collected, and the material which does not pass through should be further reduced before it is passed to the conveyor. Our Conveyor belts are used to transport the crushed ore to the destination.

It is estimated that approximately 95% of the world's bauxite production is processed first into alumina, and then into aluminum by electrolysis. This ore are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory. So in order to mining bauxite, we should choose the right combination of mining equipments. Only Iin that way can we get the higher efficiency and returns.

Williams is an industry-leading roll crusher manufacturer and designer for high-quality roll crushers with desirable benefits such as high throughput capacity, minimal maintenance requirements, low cost per ton operation, and more. Learn more about our heavy-duty roll crushers below or contact our sales engineers to talk about your application needs.

A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher. The material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material. The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. This creates a more consistent product size.Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple andinternal parts are readily accessible.

Typical feed materials for Williams Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.

Williams Roll Crushers are used in a variety of industries such as, mining recycling, and power industries. Interested in learning more about the Williams Roll Crushers for your specific industry and application? Contact our sales engineers!

Choosing between a single roll crusher and double roll crusher depends upon the type of feed material, feed size, product size desired, and consistency of both feed and product. Both single and double roll crushers operate most efficiently with dry, friable materials. However, single roll machines have been widely and successfully used for the reduction of moist clays. They also have been long used as primary and secondary coal crushers, both at mine sites and power plants, where a minimum of fines is desired.

Williams single roll crushers reduce via a combination of impact, shear, and compression. The rolls are always toothed in patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities and are particularly well suited to be used as lump breakers.

Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.

Oversized, heat-treated, alloy steel shafts plus self-aligning, roller-type bearings assure long life and maximum use of power. Jackshafts for control of roller speed are standard on double roll crushers, optional on larger Single Roll Crushers.

Heavy-duty compression springs permit movement of floating roll to pass tramp metal and other uncrushables, avoiding overload and damage. Smaller Single Roll Crushers are equipped with a shear pin release.

Faces Tooth patterns and corrugations to fit feed material; abrasion-resistant alloy; easily replaceable. Ash Crushers have additional features including dust-tight design and sealed cover plates for breaker plate access.

Williams Single Roll Crushers are also available in a 15 inch (381mm) diameter dust-tight version for applications such where it would be expensive to have dust collection air. Already well known for rugged construction, low profile, high reduction ratio, and economical cost, Williams Dust-Tight Ash Single Roll Crushers also have easy access to the rotor for maintenance. These dust-tight roll crushers are perfect for applications such as crushing ash, limestone, coal, or glass.

Hammermill Crushers are known for providing greater reduction ratios in a variety of materials for the aggregate and industrial markets. The Universal HammerMaster and LimeMaster are available in several model sizes and focused on the aggregate industry. Universal Industrial Hammermills are available in three different styles of mills and numerous model sizes in each style. The heavy-duty, rugged construction of all Universal Hammermills allow for greater applied forces to achieve higher production rates with controlled product top size and gradation.

Through years of experience and refinement, McLanahan engineers have designed two distinct families of Hammermill Crushers. These crushers are capable of processing a wide range of materials. If you are looking for reliable performance and a solid return on your investment, McLanahans Universal lines of Hammermill Crushers are the perfect answer for you. With numerous models to choose from, and a wide selection of hammers and grate combinations, McLanahan can provide a specially formulated mill to fit your specifications, along withcustomer support to ensure it runs efficiently for the life of the machine.

The Universal HammerMaster has been refined over many years, beginning with the Universal Pulverizer nearly a century ago. The HammerMaster is a high-speed mill noted for its ability to generate high-quality aggregates, cubical in shape, with superior soundness. Available in three sizes, the HammerMaster is known for making excellent asphalt chip material, concrete stone, and general base material and road rock. This mill is also capable of making agricultural lime for pH control in farm fields.

The Universal LimeMaster was developed over the same time period as the HammerMaster and incorporates many of the same components. However, the LimeMaster is solely focused on generating pulverized lime. Most limestone quarries and mines produce an abundance of fines. In some cases, with careful screening they can create a marketable aglime or chemical lime without further investment. As these markets expand, the LimeMaster can be added to the operation and greatly increase the production of this valuable product, also known as calcium carbonate.

Universal Industrial Hammermills are available in three distinct styles designed around specific types of operations. We offer the Standard Hammermill, the Non-Clog Hammermill and the Centerfeed Hammermill. All the Industrial Hammermills share a common emphasis on severe-duty construction and the ability to conform to a broad range of application issues. The Standard and Non-Clog Hammermills are considered primary crushers, with some models capable of accepting a maximum feed size of 72" (1,830mm). The Centerfeed Hammermill is a secondary crusher designed to accept feed from a primary with controlled top size ranging from 3" to 5" (75mm to 125mm). Industrial Hammermills are not limited to limestone or gypsum they are known worldwide for processing bauxite, nickel ore, phosphate ore, coal, pet coke, clay, shale, and of course, limestone.

All Universal Hammermills work on three principal reduction methods: impact, shear and attrition. As material enters the mill from a vertical chute, it comes in contact with the leading edge of the hammers, each of which is firmly secured to the spinning rotor. The hammer is pinned to the rotor body and allowed to swing, and lay back to some degree. The centrifugal force keeps the hammers extended, and the inertia force unleashed on the material shatters the rock on impact. The particles rebound off the impact plates or breaker blocks back into the hammer circle. In an instant, the material is carried into the grate or cage assembly, where shear forces reduce the larger particles and carry them across the grate surface, grinding the particles into a controlled gradation. Openings in the grates and cage assemblies allow particles to escape the mill once they are reduced to the appropriate size.

Hammermills can be used to achieve a number of goals beyond simple material reduction. In many limestone formations, seams or stratus contains soft deleterious material like chert, shale or mudstone. This material can adversely affect the value of the finished product. A hammermill can be set to pulverize the soft stone and shear the edges of the harder stone in a single pass through the mill. Screening after the mill allows for separation of the pulverized deleterious material, while the more cubical stone continues through the system.

The Standard and Non-Clog Industrial Hammermills are designed to reduce the material to a nominal 3" to 5" (75mm to 25mm) output. These are primary stage crushers, commonly followed with Centerfeed Mills or other types of secondary stage crushers. The HammerMaster is also a secondary stage crusher in that the maximum feed size is 6" (150mm). The hammers used in the HammerMaster line of mills all weigh 60 lbs (27kgs), which creates a sufficient force to fracture a 6 stone and remain extended from the rotor. The Centerfeed Industrial Hammermills incorporate various hammers of size and weight. Larger models of Centerfeed Hammermills may allow up to 8 (200mm) maximum feed size.

Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.

Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy.

Testing for abrasive characteristics in the material is a logical first step when considering the cost to replace hammers and liners. In some instances, when you are replacing a similar type Hammermill also fitted with manganese wear metal, this is less of a factor. However, in new installations, chemical analysis of the material is strongly recommended. This also applies when expanding the mine into formations where material characteristics may be changing.

Drive and power components are important not only for budgetary reasons, but also due to line power restrictions from the utility company. Hammermill Crushers often require a 1:1 ratio comparing horsepower to tph throughput. That ratio can grow to 3:1 for many applications, and even 5:1 when fine-grinding is required.

Direct drive via a flexible coupling is often the choice, when and if a motor of the same rpm can be locally sourced and serviced. However, this limits the ability to change rpm in case of changes in material formation or product specifications.

Dual motor drives allow for smaller standard frame motors, which may be more available at lower, competitive prices. You may also save on operating costs if one of the motors is wired with a solid state reduced voltage starter. Peak amperage draw is kept at a minimum when starting the crusher with the reduced voltage starter. The second motor is engaged via across-the-line starter only after the crusher is fully up to speed. Utility companies often charge a premium for peak amperage draw.

HammerMasters and LimeMasters are also available with replaceable tip hammers in lieu of the standard bullhead hammers. They are also offered with an optional feed chute to accommodate the conveyor feed.

Industrial Centerfeed Hammermills are also available with a trap mechanism located under the rotor at the central discharge point. This trap blocks the flow of material, forcing all the material to extrude through the grate openings. This trap also provides a relief for any tramp iron that may enter the chamber. A mechanical arm extends through the base frame to provide easy access when time to empty the trap, which is secured with a pivot pin and hinge.

Hydraulic access into the crusher is also available for the larger Industrial Hammermills. Not only can McLanahan offer hydraulic adjustment, the same hydraulic power unit can be used to open and close the access hatch for inspection and maintenance.

When a Hammermill is selected and recommended for a specific application, the crushing chamber with grates, impact plates and the hammers will be taken into account in the valuation of the Hammermill.

In most cases, the capacity of a Hammermill Crusher is based on the desired reduction ratio, the toughness of the material and the energy applied to accomplish the reduction. The diameter and width of the rotor assembly accommodates the top size of the feed and the surface area necessary to grind and extrude the ouput. The amount of energy applied will then result with a design capacity, which will always fluctuate with changes in the toughness or friability of the material. Essentially, for the Industrial Hammermills it is best to rely on the Bond Theory to determine necessary horsepower.

In the case of the HammerMaster and LimeMaster crushers, McLanahan has designed the crusher with rotor dimensions, shaft and bearings to handle a variety of applications at a specific horsepower rating. Since the power element is fixed, capacities can be pre-determined based on limestone and various reduction ratios.

Used as both primary and secondary crushers, McLanahan Hammermill Crushers incorporate grates, which when desired, ensures controlled product sizing as material must be to-size when it passes through the grate to exit the machine. These machines provide superior reduction ratios for a variety of low to medium abrasive materials and can be engineered for various applications.
