Background

Carbon black (carbon black), also known as carbon black, is an amorphous carbon. The carbon-containing powder is light, loose and superfine black powder, has a very large surface area ranging from 10 to 3000m2/g, is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil and the like) under the condition of insufficient air, is called as 'gas black' made of natural gas, is called as 'lamp black' made of oil and is called as 'acetylene black' made of acetylene. In addition, "channel black" and "furnace black" are also included. According to the properties of carbon black, the carbon black is divided into reinforcing carbon black, conductive carbon black, wear-resistant carbon black and the like. Can be used as black dye for manufacturing Chinese ink, printing ink, paint and the like, and also can be used as a reinforcing agent of rubber.

However, although the existing production method can produce the carbon black powder device, the existing production method still has a plurality of defects: 1. the existing carbon black production device has the problems of high difference in carbon outlet of equipment during production, and carbon black is directly transferred to the carbon black device through a carbon black collecting box or a carbon black collecting box, so that the carbon black is greatly dusted, and the environment is polluted. 2. Current carbon black is after preliminary generation, and inside contains a small amount of moisture, when not carrying out preliminary drying, causes the not good problem of carbon black large granule crushing efficiency easily, and current carbon black recovery unit directly adsorbs carbon black, has caused the waste of carbon black when having prolonged crushing time. 3. The inside rubbing crusher of current carbon black blending device adopts big blade helical shape to smash, and makes vibrations about whole device, and this kind of effect can not carry out the powderization with the carbon black, and is stirring the in-process of board and adsorbs the carbon black on the inside wall and the bottom of device easily, and the stirring of carbon black can only be realized to this kind of device. 4.
