CRGM series carbon black superfine grinding mill also known as ing roller mill is suitable for the super fine grinding of all kinds of crisp materials whose Moh’s hardness is below 7, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, white mud, mica, refractory material, glass, total about 1000 kinds of materials.

Application of ultrafine carbon black powder

Carbon black powder is a versatile material with a wide range of applications across various industries. In the rubber industry, it is primarily used as a reinforcing filler in tires and other rubber products, enhancing their strength, durability, and resistance to wear and tear. In the plastics industry, carbon black serves as a pigment and UV stabilizer, improving the color and longevity of plastic products exposed to sunlight. Additionally, it is utilized in the production of inks, coatings, and paints, where it provides deep black coloration and improves conductivity. In the electronics sector, carbon black is used in the manufacture of batteries, conductive plastics, and other components that require electrical conductivity. Furthermore, it finds applications in environmental protection, such as in water purification systems and as an adsorbent for hazardous materials. The diverse properties of carbon black powder make it an indispensable material in modern industrial applications.

the fineness 300-3000 mesh adjusted

The fine powder processed by the ore ultrafine roller mill can be widely used in PVC, paint, construction, petrochemical, stone paper, and other industries, and is the food for industrial production.

Working principle of Carbon Black Superfine Grinding mill-ring roller mill

Micro Powder Grinder is mainly formed by a mill body, blower fan, ultra-fine analyzer, finished product cyclone container, bag de-duster, and air pipe. The elevator, storage bin, electric control cabinet, powder feeder and crusher are optional for the demands of customers. 

When the grinding mill is at work, the main bearing and each dial are driven by an electromotor through the reducer, and all the grinding rollers are rolling in the ring channels driven by the dial through a plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall into the grinding chambers. The high-pressure air blower constantly inhales air, and airflow with crushed materials is brought to the classifier whose high-speed impeller will screen the airflow: The unqualified particle size will fall and return to the mill for being reground. In contrast, the qualified particle size mixed with air will go into the cyclone powder collector. Most qualified powders will fall and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The conveyor sends the materials from the above two lots to get the finished powders packed. In addition, filtered clean air will be emitted from the muffler in the end.
