Product features:
HD 1620 improved pulverizer is a kind of mill between 5R and 6R designed by our company's engineers and technicians according to the market demand. It has high output and low energy consumption.
The machine has the following features:
1. High output: the output of this model is 30% - 50% higher than that of 5r4128 Raymond machine, and 80% - 100% higher than that of 5r4119.
2. Advanced structure of main engine: optimized design of main engine cover tube structure, stable operation and low noise; quick change pressing device is adopted for host and analyzer, which is convenient for maintenance.
3. Large conveying capacity: the blower adopts high pressure centrifugal fan, the air volume and air pressure increase, which greatly improves the pneumatic conveying capacity.
4. High classification accuracy: the classifier adopts squirrel cage cone turbine classifier, and the particle size of finished product can be adjusted within 80-400 mesh.
5 Arc non resistance air duct: the air duct adopts arc-shaped non resistance air duct design, which can reduce air resistance and air loss, make the material flow well and increase the powder selection rate of analyzer.
6. New type roller grinding device: the new strong sealing structure is adopted for the grinding roller device, with reliable sealing, and the bearing is lubricated by oil, with low oil consumption and low maintenance cost.
7. Large amount of shovel material: super large blade is used to make the maximum amount of material into the grinding roller and grinding ring for grinding. The blade is made of alloy steel, which is durable.
