Working Principle

The working principle of the high pressure mill is as follows:

After entering the high pressure mill, the material is first driven by the centrifugal force generated by the rotation of the motor reducer and the suspension roller, and is fed into the abrasive layer between the grinding rolls. As the abrasive layer continues to compress, the material is gradually ground under the action of shear force and extrusion pressure. At the same time, the blade scoops up the material and sends it between the mill roller and the mill ring, where it is further rolled and kneaded to refine the powder.

During the grinding process, the powder is continuously extruded and screened by an classifier. Powders that meet the requirements are drawn into the blower, while large particles that do not meet the requirements continue to be ground on the roller until the fineness requirements are met. The finished powder is discharged from the discharge outlet, collected and packaged, and can be used as a finished product.

Throughout the operation of the high pressure mill, by adjusting the length of the high pressure spring, a constant grinding pressure can be maintained between the grinding roller and the grinding ring to ensure stable output and fineness. At the same time, in order to ensure that the system works under negative pressure, the excess air will enter the bag dust collector for purification.

Application Area

The application of high pressure mill is very wide, it can be used to process materials of various hardness, such as barite, limestone, ceramics, slag and other 680 kinds of non-flammable and non-explosive materials. After being processed by high pressure grinding mill, these materials can become a variety of particle size ultrafine powder, widely used in mining, metallurgy, chemical, building materials and other industries in the production process. At the same time, the high pressure mill can also be used in highway construction, water conservancy and hydropower engineering fields, as the processing of quartz, feldspar, calcite, limestone, talc, ceramics, marble, granite, dolomite, bauxite, iron ore, barite, bentonite, coal gangue, coal and other materials.

In addition, the high pressure mill can also be used in the processing of  activated carbon and other non-flammable and non-explosive materials whose humidity is less than 8% and Mohs hardness is below 6.

In summary, the application field of high pressure grinder mill is very wide, it can be used in various hardness of material processing, especially suitable for high fineness, high efficiency grinding production needs.
