Carbon black is an amorphous carbon. The appearance is a light, loose and extremely fine black powder with a very large surface area. It is a product of carbonaceous materials (coal, natural gas, heavy oil, fuel oil etc.) which are incompletely burned or decomposed by heat under insufficient air conditions.


Carbon black is mainly used as a reinforcing agent and filler for rubber, and its consumption is about half of the rubber consumption. The carbon black for rubber accounts for 94% of the total carbon black, of which about 60% is used for tire manufacturing. In addition, carbon black is also used as a colorant for inks, coatings and plastics, as well as an ultraviolet light shielding agent for plastic products. It is also an important adjuvant in many other products such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes. Here, carbon black can be classified into three types according to the use and use characteristics: carbon black for rubber, pigment black and conductive carbon black.

Raymond mill

(1) Carbon black for rubber, such as tire industry, rubber seals, shock absorbing parts etc., a certain amount of carbon black in rubber products can play a reinforcing and filling role to improve the performance of rubber products;

(2) Pigment carbon black, mainly used in the ink, paint and other industries as a black pigment;

(3) Conductive carbon black, using some of the low-resistance or high-resistance properties of carbon black, to make it into a conductive carbon black in different products, such as conductive rubber, radio components and so on.

Equipment recommendation

Guilin Hengda Mining Machinery Co., Ltd is a professional grinding equipment manufacturer, for 80-600 mesh carbon black, HD series raymond mill is good choice, it can be used to non-metallic minerals with Moh’s hardness under 6 and water content less than 6%, such talc, gypsum, calcite, barite, dolomite, marble, fluorite, limestone, bentonite, kaolin, carbon black, calcium carbonate and so on. Here is the advantages of HD series raymond mill as below:

1.High capacity and low consumption, the output is increased by 20%-30% compared with traditional Raymond machine, impeller type fan is used, which efficiency is higher than straight blade type fan, once oil can be used for 30-45 days;

2.Powder classification accuracy is higher, without coarseness missing, the accuracy is 80-600 mesh, classification efficiency of 99%;

3.Efficient and stable, grinding roller and grinding ring always contact during operation; environmental protection, low vibration, low noise.
