What is Aluminum Ore


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.

The use of aluminum ore


1. Aluminum foundry industry:

It can be used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.

2.Precision casting:

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.

3.Refractory products:

High alumina bauxite clinker has refractoriness up to 1780℃, chemical stability and strong physical properties.

4.Aluminum silicate refractory fiber:

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.

5.Construction sector:

Aluminum produces bauxite cement, abrasive materials, various compounds that can be used in the ceramic industry and the chemical industry to produce aluminum.

Aluminum Ore Powder Making Equipment Selection Program

Fineness200-400 mesh
ModelVertical mill or Raymond mill

Stage 1: Crushing of raw materials

The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).

Stage 2: Grinding

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.

Stage 3:Classification

Through classification, the coarse powder will return to main mill to grind again.

Stage 4:Collection of finished products

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.
