Product description of high pressure suspension roller mill:
The high-pressure suspension roller mill is mainly suitable for processing various non-flammable and explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%. It is used in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower And other industries have a wide range of applications, processing quartz stone, potash feldspar, calcite, limestone, talc, ceramics, marble, granite, dolomite, bauxite, iron ore, barite, bentonite, coal gangue, activated carbon, Ideal for more than 280 kinds of materials such as coal, the fineness of the boring finished product can be adjusted between 0.198 mm-0.33 mm (80 mesh-425 mesh). The mill can produce coarse powder of 0.613 mm (30 mesh) through a special device.
Working principle of high-pressure suspension roller mill:
For the high-pressure suspension roller mill, 1000-1500 kg pressure spring is fastened on the roller hanger. After starting to work, the grinding roller rotates around the main shaft and should be rolled close to the grinding ring under the action of high-pressure spring and centrifugal force. Its rolling pressure is 1.2 times higher than that of the Raymond powder machine under the same power condition, so the output is greatly improved. When the material to be material enters the grinding cavity, it is scooped up by a spatula and sent between the grinding roller and the grinding ring for rolling. The powder after rolling is brought into the analyzer with the circulating air of the blower, and the qualified fine powder enters with the air flow. The cyclone powder collector is the finished product, and the large particles fall back to regrind. The circulating air returns to the blower to repeat the above process, and the remaining air enters the bag filter for purification. When the grinding roller and the grinding ring reach a point of wear, adjust the length of the high-pressure spring to maintain a constant grinding pressure between the grinding roller and the grinding ring. So as to ensure stable output and fineness.
Performance characteristics of high-pressure suspension roller mill:
1. Unique design. In the main machine grinding cavity, a 1500kg-2000kg pressurizing device is designed on the upper part of the plum blossom frame. Under the same power, the output has increased by 10%-30%, and the grinding device can increase the material rolling by 800-1500kg. , The fineness of the finished product can reach 1000 meshes.
2. The material has strong applicability and can be used for various materials with Mohs hardness below 9.3.
3. The dust removal effect fully meets the national standard
4. The roller grinding device adopts high-quality and high-efficiency processing technology, and the overlapping test multi-stage seal ensures good results
5. The replacement cycle of the grinding roller and the grinding ring is long, eliminating the shortcoming of the short replacement cycle of the wearing parts of the centrifugal crusher
6. The grinding device adopts overlapping multi-stage sealing with good sealing performance.
