Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. Approximately 70% to 80% of the world's dry bauxite production is processed first into alumina, and then into aluminium by electrolysis as of 2010. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory.
Processing and washing plant for bauxite needs some mining machines, such as washer machine, flotation machine, high frequency screen, grinder machine and jaw crusher.In romania, there are many mining processing and washing machine suppliers. Shanghai SBM is a professional mining processing machine manufacturer and supplier in the world, especially in romania.
One of is sand washing machine, which also can be used for other materials washing.
LSX series screw sand washing machine is efficient sand washing equipment, which adopts advanced technology at home and abroad and the actual conditions of sand industry development.
It is applied to the metallurgical, building materials, water and electricity industries such as washing, grading, cleaning and washing operation, suitable for fine-grained and coarse-grained materials, the building sand, sand road of appropriate.
When it is at working, the motor through the belt, reducer, gear reducer drives the impeller to rotate slowly, the sand with the feed chute into the washing groove, rolling in the impeller drive, and mutual grinding, remove the gravel covered surface impurities, and destruction of water vapor coated layer of sand, in order to facilitate dehydration; at the same time, add water, the formation of a strong current, timely foreign impurities and the proportion of small away, and from the overflow outlet washing tank discharge, complete cleaning effect. Clean gravel from the leaves away, finally into sand trough from the rotation of the impeller, complete sand cleaning effect.
