The calcite vertical roller mill conical grinding roller has an inclination angle to the grinding disc. The grinding roller is mainly rolling friction in the grinding grinding process, while the rolling resistance of the large diameter grinding disc is small, so the unit energy consumption is low. The composite roller sleeve has good processability and weldability and long service life. The crank arm is loaded, and the swinging arm that is responsible for fixing and guiding the grinding roller is located outside the cylinder of the vertical roller mill.
The calcite vertical roller mill powder abrasive layer is only 20-30mm, and the particles are easily crushed, so the energy consumption is low and the efficiency is high. The annular nozzle around the grinding disc is specially designed to reduce the ventilation resistance of the nozzle to prevent the nozzle from blowing upwards to cause air abrasion on the grinding roller and other parts. For the ore powder vertical roller mill, the annular nozzle is provided with a bypass device to make the iron piece The discharge chute that has no air flow is separated and then removed by the metal separator to reduce the wear of the internal parts of the vertical roller mill to a small extent.
For different capacity requirements, design different sizes and quantities of grinding rolls, including auxiliary rolls to enhance the stability of the bed, 2+2 (3 + 3) form of the grinding roll design is more suitable for grinding calcite.
The design of the spring-loaded system buffer of the calcite vertical roller mill liquid-gas combination makes the metal parts of the vertical roller mill have no metallic contact during the whole operation.
Calcite vertical roller mill has advanced concept of grinding machine, simple process and small installed capacity. Grinding ultra-fine mineral powder can save 45-60% of electric energy compared with traditional tube grinding system, and grinding cement can save 35-40 % of electricity.
1. The grinding roller has low running resistance and low energy consumption.
2, horizontal grinding disc, center cutting, uniform cloth
3, targeted design
4, a better loading system
5, the energy saving effect is more obvious
