Bauxite, also known as bauxite or bauxite, the main component is alumina, hydrated alumina containing impurities, is a soil-like mineral. White or grayish white, brownish yellow or light red due to iron content. Hardness 1 ~ 3, opaque, brittle, extremely difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminum smelting, refractory products, grinding materials, military, aerospace, communications, instrumentation, machinery, medical equipment casting.

Bauxite grinding powder general fine powder processing ( 80 mesh-400 mesh ), ultra-fine powder processing ( 400 mesh-1250 mesh ) and micro powder processing ( 1250 mesh-3250 mesh ) three types.

Crushing : Bauxite bulk materials by crusher to enter the mill feeding fineness ( 15mm-50mm )

Grinding : crushing bauxite after small pieces of material sent to the hopper by hoist, and then through the vibration feeder uniform quantitative into the grinding mill grinding chamber for grinding.Fine powder processing generally use LM vertical mill, MTW European mill, 5X European intelligent mill ; ultra-fine powder processing generally uses LUM ultra-fine vertical mill, MW ring roller mill ; sand or coarse powder processing selection CM European coarse grinding, straight through centrifugal grinding

Grading : the material after grinding is graded by the powder selecting machine, and the unqualified powder is graded by the powder selecting machine and returned to the host for regrinding

Powder collection : The powder that meets the fineness enters the dust collector through the pipeline for separation and collection, and the collected finished powder is sent to the finished material warehouse through the discharge port by the conveying device, and then uniformly packed with a powder tanker or an automatic baler.
