High-Pressure Mill

High-pressure mills, also known as high-pressure grinding rolls (HPGRs), are a type of comminution equipment used for crushing and grinding materials by applying intense pressure. They are highly efficient and are primarily used in the mining, cement, and chemical industries. HPGRs can be classified based on several key characteristics.

Performance Features
1. Compared to other grinding mills, the grinding rollers exert 800-1200 kg of force on the material due to the action of high-pressure springs.
2. Energy-saving: With the same output and fineness, the system energy consumption is only one-third of that of an air jet mill.
3. Low investment, high efficiency: With the same output and fineness, the price is only one-quarter of that of an air jet mill.
4. Fewer production steps: Compared to air jet mills, high-pressure micro-powder mills must first crush 20 mm materials to 100 mesh before producing ultrafine powder. High-pressure micro-powder mills can directly produce ultrafine powder with an average particle size of less than 6.5 μm from feed particles below 20 mm. [Finished particle size 500-1250 mesh (0.01)]
5. The grinding mechanism utilizes overlapping multi-stage seals for excellent sealing performance.
6. The high-pressure micro-powder mill's dust removal efficiency fully meets national dust emission standards.
