Aluminum refers to the mineral that can be used in industry and is composed of gibbsite, boehmite or diaspore as the main minerals. Bauxite is usually deposited in marine and lake basins, and can also occur in weathered crusts of basalt or other rocks. Many useful elements such as gallium, vanadium, lithium, rare earth metals, niobium, tantalum, titanium, and scandium are also associated with bauxite ore, which has a very high application value.
It can be used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.
Bauxite clinker processed into fine powder can be made into molds and then precision melted, widely used in military, aerospace, communications, instrumentation, machinery and medical equipment.
High alumina bauxite clinker has refractoriness up to 1780℃, chemical stability and strong physical properties.
Aluminum has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small thermal capacity, and mechanical vibration resistance. It is used in various industries such as steel, non-ferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense, etc.
Aluminum produces bauxite cement, abrasive materials, various compounds that can be used in the ceramic industry and the chemical industry to produce aluminum.

| Model | Vertical mill or Raymond mill |
The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).
The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.
Through classification, the coarse powder will return to main mill to grind again.
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
