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 SBM crusher or SBM 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 SBM mining equipments for bauxite crushing. As the leading stone crusher manufacturer and Ore Milling Equipment, SBM has also been closely following the bauxite mining at home and abroad. SBM 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. SBM mining equipments have been exported to more than 130 countries which are widely applied in mining industry including the bauxite crushing. For decades, SBM 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.
Shanghai SBM,the best Bauxite Grinding Plant manufacturer,is not only professional in China Bauxite Grinding Plant For Sale,but also has exported Bauxite Grinding Plant for several years.
Introduce of bauxite ore grinding plant:
The purpose of bauxite grinding plant/bauxite powder processing plant is for grinding materials with hardness less than 6 in Moh’s scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble,talcum, barite, gypsum, dolomite, bentonite mud,mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on.
Technical Advantages of bauxite grinding plant/bauxite powder processing plant:
● High Efficiency
Under the same finished final size and the same motor power, the capacity of HGM series micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
● Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
● High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
● High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise. ●Advanced intelligent speed control device Convenient adjusting, more uniform particle size.
The bauxite grinding plant/bauxite powder processing plant mainly consist of hammer crusher , main unit, Frequency conversion classifier, powder collector, pulse dust cleaner,high pressure positive blower, air compressor, muffler, electrical apparatus control system, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder. Working Principle of bauxite grinding plant/bauxite powder processing plant: The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
