Introduction to CSM280 Small Special Ultrafine Mechanical Grinder for Pitch Coke

Developed and manufactured with authentic German technology combined with sophisticated Chinese manufacturing, the CSM280 small ultrafine mechanical grinder is specially designed for grinding pitch coke. It is also compatible with petroleum coke, graphite and other materials, and is widely used in fine chemicals, minerals, food & feed, pharmaceuticals & healthcare, electronics, military industry, non-ferrous metals and other industries. Having successfully served internationally renowned powder material enterprises, it has gained market recognition for its efficient and stable performance.

I. Core Features of CSM280 Small Ultrafine Mechanical Grinder

This equipment is optimized and upgraded on the basis of the German ACM air classifier mill, with key improvements to the hammer head and gear ring structure. High wear-resistant alloy materials are adopted to maximize the efficiency of material friction, shearing and collision. Meanwhile, the system configuration is optimized in line with domestic technical capabilities, balancing high-efficiency grinding and stable operation. The specific features are as follows:

• Adopting the foreign high-efficiency grinding structure with a rational match of the high linear speed of the moving disc and the sharp angle of the gear ring, the grinding efficiency is greatly improved with more reasonable energy consumption.
• Equipped with a conical classifying impeller, it can effectively sort qualified products by particle size under the action of the guide ring and reduce direct friction. The classifying impeller is processed with a special process with excellent dynamic balance, ensuring stable operation of the equipment.
• Adopting imported high-sealed SKF bearings, it is durable and wear-resistant with stability far superior to similar domestic bearings, effectively extending the service life of the equipment.
• The grinding hammer heads are protected with alloy materials, featuring outstanding wear resistance, reducing metal contamination of products and ensuring material purity.
• Equipped with a professional collection system matched with system air volume and pressure, it operates under negative pressure with no dust leakage, meeting environmental protection requirements.
• Specially designed with a high-air-volume cooling structure for the temperature requirements in pitch coke grinding, it avoids material deterioration caused by high temperature and guarantees grinding quality.
