Silica Sand Magnetic Separator

STL is one of the leading manufacturers of ore dressing equipment. The present range of stl Process equipment enables us to provide complete packages. Magnetic wet separators constitute an important part of the product range and are known for advanced engineering design and excellent performance. As a result of continuous development in separator technology stl can offer a complete line of magnetic wet separators to the mining and mineral industries.

Product models and sizes:stl's wet permanent magnetic separators are offered in sizes of dia. 1200 mm and 916mm in lengths of up to 3000mm. Three basic separator designs are available for cobbing, roughing and finishing/cleaning applications. Each type can be supplied in single drum or multiple drum stages of taconite or magnetite and also for recovery for magnetic medium in dense media plants. The stationary magnet yoke is an assembly of strontium-ferrite permanent ceramic magnets. The rotating drum is available with optional rubber or stainless steel covers. The magnetic flux pattern will match the tank configuration for optimum performance. Stl's magnetic wet separator dia 916 x 300 mm is the smallest full scale separator in the 916 series and is primarily used for pilot plant tests. The separator can be delivered in concurrent, countercurrent and counter rotation versions. Stl's magnetic wet separator for laboratory use have drum dimensions dia. 600 x 285 mm and dia. 200 x 100 mm and are suitable for batch or continuous testing. The test results from the stl laboratory separators correspond closely to those obtained in full scale operation. pilot unit dia. 916 x 300mm. Left.

Adjustment of magnet yoke and drum: The magnet yoke is mounted on the stationary drum shaft and its position can be adjusted (+/-35) by a lever at the end of the drum shaft to optimize runing conditions in accordance with tank design and type of ore. The gap between tank and drum, which determines the pulp flow speed, can be adjusted vertically by shims inserted under the bearing housing and shaft support. Horizontal adjustment is by slotted holes.

Silica Sand Processing Flotation Machine

Froth Silica sand processing flotation machine is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In Silica sand processing flotation machine, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise through the slurry and are collected from the surface. To enable these particles to attach, careful consideration of the chemistry of the pulp needs to be made. These considerations include the pH, Eh and the presence of Silica sand processing flotation machine reagents. The pH is important as it changes the charge of the particles surface and the Eh effects the chemisorption of collectors on the surface of the particles.

The addition of Silica sand processing flotation machine reagents also effects the operation of these processes. The most important chemical that is added is the collector, This chemical binds to the surface of the particles as it is a surfactant. The main considerations in this chemical is the nature of the head group and the size of the hydrocarbon chain. The hydrocarbon tail needs to be short to maximize the selectivity of the desired mineral and the headgroup dictates which minerals it attaches to.

The frothers are another important chemical addition to the pulp at it enables stable bubbles to be formed. This is important as if the bubble coalesce, minerals fall off their surface. The bubbles however should not be too stable as this prevents easy transportation and dewatering of the concentrate formed. The mechanism of these frothers is not completely known and further research into their mechanisms is being performed.

Depressants and activators are used to selectively separate one mineral from another. Depressants inhibit the Silica sand processing flotation machine of one mineral or minerals while activators enable the Silica sand processing flotation machine of others.

There are a number of cells able to be used for the Silica sand processing flotation machine of minerals. these include Silica sand processing flotation machine columns and mechanical Silica sand processing flotation machine cells. The Silica sand processing flotation machine columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical Silica sand processing flotation machine cells. The cells in use at the moment can exceed 300 m3.
