Strengthen the superior performance of ultrafine mill

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Strengthen the superior performance of ultrafine mill

Strengthen the ultrafine mill mainly by the roller device, disc device, roller hydraulic loading device, hydraulic lubrication system, reducer, motor, electrical, high-efficiency classifier and other components. When strengthening the work of ultrafine pulverizer, the motor drives the disc to rotate through the reducer. At this moment, the wind enters into the vertical mill body from the air inlet. The slag and other materials fall into the middle of the disc through the feeding port of the feeder and are rotated by the disc. When the centrifugal force is applied, the material is thrown to the edge of the grinding disc by the grinding roller, and the large pieces of material are directly crushed, and the small particles form a material bed for intergranular pulverization.

After the crushed slag material arrives at the edge, it is carried away by the strong wind at the wind ring. The heavy material particles fall on the grinding disc and continue to grind. After the material in the airflow passes through the upper separator, the coarse-grained material is passed by the rotor blade. Block back to the grinding plate to re-grind. The qualified materials are ground with the air flow and collected by the powder collector.

The advantages of strengthening ultrafine mills are as follows:

  • 1. High milling efficiency: The grinding method of directly grinding and grinding the grinding material on the grinding disc by the grinding roller has low energy consumption and saves 30% to 40% energy consumption compared with the ball milling system.
  • 2, less wear: As the work of the roller does not directly contact with the disc, and the roller and the liner are made of high-quality materials, so the long life, wear less.
  • 3. The time for the material to stay in the mill is short, it is easy to detect and control the product particle size and chemical composition, and it reduces the repeated grinding. The product quality is more stable.
  • 4. The roller sleeve and the liner are not in direct contact with each other. The iron content in the product is very small, and the mechanical wear iron contained in the product is easy to remove. When used to grind white or transparent materials, the whiteness and purity of the product are high. It is equipped with a limit device to prevent direct contact between the roller sleeve and the disc lining plate to avoid destructive impact and violent vibration, thus providing a significant guarantee for the quality and stability of the finished product.
  • 5, to strengthen the ultrafine grinding machine equipped with PLC / DCS automatic control system, can achieve remote control, easy to operate. By overhauling the cylinder, turning the boom, replacing the roller bushing and lining board is quick and easy, reducing the downtime loss.
  • 6, energy-saving environmental pollution-free equipment, low vibration, low noise.
  • 7. Strengthen the ultrafine grinding machine to integrate crushing, drying, grinding, grading and conveying. The system is simple, the layout is compact, and it can be arranged in the open air, thus reducing a lot of investment costs.
