Introduction to the difference characteristics of small ball mill
Cement test small grinding operation program
1. Weigh clinker, gypsum or other materials to be ground.
2. The material should be crushed before grinding, and the particle size is generally less than 7 mm.
3. Clear the remaining material in the mill body, and then pour the broken material into the mill.
4. Cover the door tightly and tighten the bolts.
5. Start and stop the switch according to the needs of grinding time.
6. Start the mill for grinding.
7. If the fineness of the sample is taken into the specific surface area during the grinding process, it should be stopped for 2-3 minutes after the shutdown, and then the grinding powder is sampled after the grinding powder is settled.
8. When the grinding material reaches the required fineness, replace it with the discharge door after stopping, and then start the grinding machine to pry out the good material until it is clean. (If the exhaust device is installed, it should be Stop the exhaust).
9. Wait for 5 minutes, wait for the material to settle basically, then open the reclaimed materials and take out the good materials.
Cement test small mill installation:

Check the gear reducer motor, barrel, etc., whether the bearing seat is damaged during transportation, whether the fastener is loose or not. If it is loose, it should be loose. Tighten, then hoist, the application rope is attached to the seat, not attached to the cover, shaft, motor, to avoid damage to the parts.
During installation, the dirt on the bottom plate of the support should be removed first, and the surface of the cement foundation should be leveled to remove debris. The support should be placed in a stable position and allowed to be leveled with steel spacers.
