High pressure grinding 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.
High Pressure Grinding Mill Application
High Pressure Suspension Grinding Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. The grinding mill can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, calcite, granite, porcelain clay, basalt, gypsum etc.
High Pressure Grinding Mill Main Features and Benefits
- 1. Compared with the common Raymond grinding mill under the same power conditions, the capacity can be increased by 10%; moreover, under the performance of high-pressure springs, the rollers grinding pressure on raw materials can be raised by 800-1200kgf.
- 2. The final product size ranges from the maximum particle diameter of 0.613mm (30mesh) to the finest diameter of 0.033mm (425 mesh).
- 3. All the mineral materials with Mohs hardness below 9.3 can be crushed.
- 4. The grinding device adopts a superposition multi-grade sealing with good sealing performance.
- 5. Its dust-removing effect fully meets the national dust discharge standard.
- 6. The classifier is easy for adjustment.

Coal Project in Indonesia
The Jembayan thermal coal operation covers an area of over 12,000ha in East Kalimantan, Indonesia. Straits Resources subsidiary Straits Asia Resources (SAR) completed its acquisition of the coal mine project in 2007 in a deal worth $350m.
Mining operations at Jembayan are undertaken using contractor PAMA. The mining method used is surface, open pit mining using truck and excavator / shovels. You can find SBM coal mills used for the coal grinding process.
Coal Mine Project in Australia
The Isaac Plains Coal mine is an open-pit mine located in Central Queensland, in the Bowen Basin region, about 7km east of the Moranbah township. The mine comprises two coal deposits, Isaac Plains North deposit and Isaac Plains South deposit, which are located approximately 15km apart. This coal mining is carried out using both truck and shovel methods in addition to dragline techniques.
Coal is delivered to an on-site coal handling and preparation plant (CHPP) where it is crushed, sized and washed by SBM coal crushers, coal mills and washers.
