Calcium Carbonate Ultrafine Vertical Roller Mill With Higher Grinding Efficiency

Calcium Carbonate Ultrafine Vertical Roller Mill with Higher Grinding Efficiency

Calcium Carbonate Ultrafine Vertical Roller Mill RPM Influence on the Grinding Efficiency:

     Henkry calcium carbonate ultrafine vertical roller mill reducer is equipped with inverter control system, so the RPM can be adjusted to achieve higher grinding efficiency.

    Rotation speed of vertical roller mill is an important factor, which can affect the grinding efficiency. As the rotation speed goes up, the friction between the grinding media and calcium carbonate is increased, so this can improve grinding efficiency. However, the rotation speed should not be too high. If The rotation speed is too high, the calcium carbonate will move out of the grinding contact surface, and the powder shape will be also influenced, and the vibration of the whole vertical roller mill will be higher. So the grinding efficiency cannot be improved. The suitable rotation speed is the right choice.

Calcium Carbonate Feeding Size Influence on the calcium carbonate ultrafine vertical roller mill grinding efficiency:

    For the feeding size, Henkry calcium carbonate ultrafine vertical roller mill is equipped with crushing system, which can control the feeding size of the raw material. If other conditions are all same, calcium carbonate feeding size have a big influence on the ultrafine vertical roller mill grinding efficiency. In order to reach the best grinding state, the feeding size should less than 50mm or 30mm(according to the mill size). There must be some bigger size (1-30mm; 40-50%); This will improve the grinding between calcium carbonate and calcium carbomate, and also improve powder shape. If the feeding material contains 80-90% powder (80-200mesh), it is not easy to form grinding layer between the roller and ring, so the grinding efficiency should be lower.

Grinding Aids Influence on the calcium carbonate ultrafine vertical roller mill grinding efficiency:

     Adding appropriate grinding aids to calcium carbonate ultrafine vertical roller mill can greatly improve the grinding efficiency and improve the dispersion performance of grinding products. The grinding aid mainly improves the grinding process by changing the calcium carbonate hardness of the material and the interaction between the particles.

    The ultrafine calcium carbonate powder can be successfully produced by vertical roller mill, whose fineness can meet the requirements of paper industry and painting industry. Rotation speed, feeding size and grinding aid are the main factors affecting the grinding efficiency of the vertical roller mill. In order to obtain high grinding efficiency, the grinding conditions should be strictly controlled.

The Advantages of calcium carbonate ultrafine vertical roller mill:

1. Wide range of powder fineness: Turbo air classifier is installed in the calcite ultrafine vertical grinding mill, which can produce powder with various fineness and higher sieving rate.

2. Lower power consumption and Higher Output

3. The calcite powder produced by ultrafine vertical roller grinding mill has a narrow particle size distribution, control gap of 2μm powder content, high profit margins and added value.

4.Because of the use of hydraulic system to adjust the gap between roller and ring, which brings lower vibration and lower noise

5. Environment-friendly and 99.99% of the powder can be collected.

6. Automatic control with PLC system to guarantee easy operation and labor saving.
