Bauxite, also known as bauxite or bauxite, is a kind of earth-like mineral, the main component is alumina, white or off-white, brown yellow or light red due to the iron content. Bauxite is generally formed by chemical weathering or exogenous action. There are few pure minerals, and more or less a small amount of clay minerals, titanic minerals, titanium minerals and detrital heavy minerals. The hardness of bauxite is 1-3, opaque, brittle, insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. White or off-white, brownish yellow or light red due to iron content. Density 3.9 ~ 4g / cm3. Mainly used for aluminum smelting, refractory materials.
Bauxite is a high-quality aluminum smelting raw material and refractory material. With the development of economy and the progress of science and technology, bauxite has been widely used in deeper fields.

Mill Recommendation
Coarse powder( 30-400 mesh) | Fine powder (600-2000 mesh) |
Vertical mill or Raymond mill | Super fine mill |
Remarks: Choose different types of hosts according to the output and fineness requirements.
The First Stage: The Crushing Of Raw Materials
The large bauxite material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.
The Second Stage: Milling
The crushed bauxite pieces are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.
The Third Stage: Classification
The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-Grinding.
The Fourth Stage: The Collection Of Finished Products
The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
