What is an aluminum ore grinding mill?

Bauxite grinding equipment, including bauxite Raymond mill and bauxite vertical mill, which can process bauxite to 80-400 mesh, which is the selection of high-efficiency aluminum ore and bauxite powder making equipment in the aluminum smelting industry.

The aluminum ore grinding mill is used in the bauxite processing and powder making industry, mainly used in aluminum smelting and refractory manufacturing enterprises. Bauxite can be used as various compounds for aluminum production in ceramic industry and chemical industry. Bauxite is inseparable from modern production and life. With the expansion of the application field of bauxite, its industrial value will continue to be explored. Bauxite is an excellent raw material for the production of aluminum metal and the main application field of bauxite.

(1). Aluminum smelting industry: it can be used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.;

(2). Precision casting: bauxite clinker is processed into fine powder and can be made into molds for precision casting, which is widely used in military industry, aerospace, communication, instrumentation, machinery and medical equipment departments;

(3). Refractory products: high-alumina bauxite clinker, chemically stable and strong, has a refractoriness of up to 1780°C and good physical properties.

(4). Aluminum silicate refractory fiber: Bauxite has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance. It isused in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries.

(5). Using magnesia and bauxite clinker as raw materials and adding a proper binder, it is very effective for casting the whole lining of the steel drum.

(6). Bauxite can be used to make bauxite cement, abrasive materials, ceramic industry and various compounds of aluminum in chemical industry.

1. Process of aluminum ore mill

The processing of bauxite grinding machine and bauxite process integrates a complete set of bauxite crushing, grinding, drying, grading and packaging processes. The first stage of the bauxite processing process is to use the high-temperature calcination process to calcine the bauxite to form two types of high-alumina bauxite clinker and light-burned bauxite. The fired bauxite is crushed and milled to obtain powders of different fineness, which can be used in different fields.

Process1

Crusher coarsely crushes bauxite into bauxite fines. Large pieces of bauxite clinker are transported to the raw material warehouse by a special vehicle, and then sent to the jaw crusher by a forklift or manually for crushing, and crushed to meet the feed size range of the mill.

Process2

The bauxite clinker crushed by the crusher is lifted to the storage hopper by the elevator, and the material is discharged from the storage hopper, and then fed to the main machine of the bauxite mill evenly by the feeder.

Process3

During the grinding process of bauxite particles in the bauxite mill, the qualified powder is blown by a high-pressure fan, screened by the screening system, and then enters the collector through the pipeline. After collection, it is discharged through the powder outlet pipe to become the finished product. Unqualified products fall into the main machine of the bauxite mill for re-grinding.

Process4

The bauxite powder is brought into the air duct by the hot air from the blower from the main body of the bauxite mill through the analyzer, then enters the pulse dust collector, enters the powder collector under negative pressure flow, and finally enters the packaging machine at the lower end of the powder collector for packaging.
