Russia is rich in mineral resources, is rare in the world most of the mineral can be self-sufficient in one of the countries. The country has about 20,000 deposit is discovered and proven. Russia’s coal production was 275.6 million tons, mainly from the Kuznets Basin (143.3 million tons), the total coal production, bituminous coal dominated Russia’s coal consumption was 1.9835 million tons, exports0.5812 million tons are mainly exported to Europe and Asia, followed by Asia. Coal mining has a very important significance.
Liming heavy industry according to the Russia coal mine features, we designed the new type coal roller mill, High Pressure Suspension Mill which is widely applied for the coal mine mining process plant.
Liming coal roller mill advances as follows:
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.
