Gulin® is a professional bauxite grinding mill manufacturer in China, and offer types of grinding machines for bauxite grinding process plant. Our bauxite grinding equipment is the important beneficiation operations at bauxite mines used for particle size reduction for separation of mineral and waste.
Bauxite grinding mill
In the bauxite grinding process, there are three steps of grinding. Grinding machine is used for grinding bauxite powder with 200 mesh. Gulin® can offer types of grinding mill for bauxite powder production, such as ball mill, vertical mill, raymond mill, coarse powder grinding mill and ultrafine mill.
Ball mill for bauxite
Ball mill is the main bauxite grinding machine used in bauxite beneficiation process. It has been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter. Ball mills are sized from 2 t/h to 30 TPH for wet grinding and from 0.5 t/h to 30 TPH for dry grinding.
Bauxite grinding flow process
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade or can be improved by a relatively simple and inexpensive process of removing clay. In many bauxites, clay is removed by some combination of washing, wet screening and cycloning, even by hand picking or sorting.
In the bauxite grinding plant, aluminum ore begins with crushing and grinding to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.
After crushing, wet grinding of bauxite is accomplished in either open or closed-loop milling circuits using various types of grinding mill designs, tailor made to the bauxite. After reclaim using bucket-wheel stacker-reclaimers, the ore is dried from an average 12.5% moisture to 6.7% for shipping.
Bauxite Deposits are located in areas varying from gentle undulating to rugged, major capital expenditures in establishing a system of ore transportation like belt conveyors and dust-control systems.
