Structural features of grinding mill

1. Three-dimensional structure, small footprint, strong complete set, from block material to finished powder, an independent production system; 2. The finished powder has uniform fineness and a screening rate of 99%, which is difficult for other grinding equipment to have; 3. The machine transmission device adopts a closed gear box and pulley, with stable transmission and reliable operation; 4. Important components are made of high-quality steel, and wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation; 5. The electrical system adopts centralized control, and the grinding workshop can basically achieve unmanned operation and convenient maintenance.
Scope of application of high-pressure suspension roller mill: High-pressure suspension roller mill is used for high-fine powder processing of more than 280 materials in non-flammable and explosive mining, metallurgy, chemical industry, building materials and other industries with Mohs hardness not more than 9.3 and humidity below 6%. The finished product particle size is adjusted in the range of 80-425 mesh (the finest is 1000 mesh). The machine can produce coarse powder of 30-80 mesh by adding special devices.
Inside the main machine of the high-pressure grinding mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting to work, the roller rotates around the main shaft and rotates closely against the grinding ring under the dual action of the high-pressure spring and centrifugal force. Its rotation pressure is 1.2 times higher than that of the Raymond mill under the same power conditions, so the output is greatly improved. When the material to be ground enters the grinding chamber, it is scooped up by the shovel and sent to the grinding roller and the grinding ring for rolling. The rolled powder is brought into the analyzer with the circulating air of the blower. The qualified fine powder is collected in the cyclone powder collector with the air flow and is the finished product. The large particles fall back to the re-grinding. The circulating air returns to the blower and repeats the above process, and the remaining air enters the bag dust collector for purification. When the grinding roller and the grinding ring reach a certain wear, adjust the length of the high-pressure spring to maintain a constant rolling pressure between the grinding roller and the grinding ring. This ensures stable output and fineness.
