Coarse Powder Mill Working Principle
the material is grinded between rotor and ring as the rotor is rotating. The ground powder will be blown into the classifier; the fine powder will be collected by the collector while the coarse powder will be regrinded to the required size.
MXB Coarse Powder Mill Application
MXB Coarse Powder Mill is used for pre-processing of various crushable non-flammable and non-explosive brittle materials with Mohs under 9. It is widely applied in quartz sand, silica sand, foundry sand, fine sand and other sand abrasive industry. It is also applied in industries of mining , construction , metallurgic, road building and water conversancy etc.
MXB Coarse Powder Mill Main Features and Benefits
- 1. High efficiency of spare parts. As materials fall from top to bottom, roller and ring are equally worn. Thus the life span could be 3 times higher than that of Raymond Mill.
- 2. High efficiency of processing fine sand. 80% of the finished sand could be finer than 1-2mm.
- 3. This machine could be used as the pre-grinding equipment before ball mill so as to increase Ball Mill efficiency by 50%.
- 4. Products out of MXB coarse powder mill can be used to make firebrick, concrete brick, block and other new building materials
- 5. Mainly used for pre-processing of various crushable non-inflammable and non-explosive brittle material with Mohs Hardness less than nine.

Grinding Project in Ghana
Ahafo operates a number of open pits with the majority of ore coming from the Apensu and Awonsu working areas.
A blend of both primary and oxide ore is fed to the grinding mill to balance the head grade and recovery in the leach circuit. SBM provided crushers and mills for the grinding project. Also there is powder classification system provided. After classification, the milling product is thickened and the overflow is fed to carbon-in-leach tanks.
Grinding Project for Chilean Market
Los Bronces Development Project in Chile Mining involves an investment between US$ 2.2 billion and US$ 2.5 billion, to build new grinding, mineral transport and concentration facilities which will increase the Division's production capacity to an average of 400,000 tons of fine copper annually, up from 230,000 tons currently.
SBM has supplied special coarse powder grinding mill and ball mills for the grinding plant expansion at the Los Bronces mine. Also we have provided primary crushers for crushing harder materials.
