Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal cracking carbon black production, in particular to a crusher for thermal cracking carbon black production. Background Art
[0002] Thermal cracking carbon black is produced by heating natural gas to 1300℃ in an air-tight state. It is composed of a large number of spherical and elliptical carbons and a small amount of fused particles. It has the characteristics of large particle size, small specific surface area, low structure, easy dispersion, good fluidity and high filling content. Because of its low surface activity, it is also called non-reinforcing carbon black. It is one of the carbon black varieties that are widely used in tire airtight layers, hoses, tapes, oil seals, and fluororubber products. In the production process of thermal cracking carbon black raw materials, it is necessary to crush them. For subsequent processing, the crushing of thermal cracking carbon black is usually carried out by a crocodile crusher. The thermal cracking carbon black is continuously impacted, so that the thermal cracking carbon black can be crushed. Although the crocodile crusher can ensure the continuous crushing of thermal cracking carbon black, the thermal cracking carbon black is continuously impacted in the crocodile crusher, and some of its thermal cracking carbon black will produce thermal cracking carbon black blocks of different sizes under the action of the force generated by the impact. Some of the larger thermal cracking carbon black blocks are very likely to be detached from the crushing chamber of the crocodile crusher before they have been impacted several times, resulting in the thermal cracking carbon black being not thorough enough, affecting its crushing quality. For this reason, we proposed a crusher for the production of thermal cracking carbon black. Utility Model Content
