High Pressure Suspension Grinding Mill

Overview of High Pressure Suspension Grinding Mill:

High Pressure Suspension Grinding Mill is a new kind of mill, which is invented by our company chief engineer Mr Bai yinghui, who has been engaged in the research and development of grinding machine for many years. This new patent product with high efficiency and low energy consumption opened up an epoch of the international industry pulverizing.

The application of High Pressure Suspension Grinding Mill:

High Pressure Suspension Grinding Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. It 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, quartz, calcite, granite, porcelain clay, basalt, gypsum,magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, kyanite, fluorspar, bentonite, medicinal stone liparite, diabase, pyrophyllite, shale red stone, emeraldite, basalt, gypsum, graphite, carborundun, heat insulating material etc. The final size is between 80 mesh and 425 mesh ( the finest could even be 800 mesh)

High pressure grinding mill can be used widely in silica grinding plant, quartz grinding plant, manganese grinding plant, iron ore grinding station, coal power plant, coal processing plant, bauxite grinder plants, cement grinding plant etc.

Features &Benefits of High Pressure Suspension Grinding Mill:

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). A few materials can reach 0.013mm (1000 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.

Working principle of High Pressure Suspension Grinding Mill:

In the mainframe of High Pressure Suspension Mill, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When it works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity. When the materials are sent into the grinding chamber, they are brought to the space between the roller and ring and get grinded. Then the powder grinded will be blown into separator. The fine powder after departed with the air is discharged through the outlet as final product. The large-sized powder falls back for regrinding. The air will be back to the blower for repetition of the above process. The left air will come to the bag filter to get cleaned. When the wear and tear between roller and the ring reaches certain degree, adjust the length of the strong spring, so to keep the invariable pressure between the roller and the ring, to make sure the stable production and the fineness.
