Calcium carbide. 1. introduction. during the ball milling, the peak intensity of organic chlorine weakened slightly at 6 h, and disappeared completely at 12 h, which indicates that the mechanochemical reaction is mainly taken place in the second 6 h,.

Lab jaw crusher. model no. : xpc brand: tencan applications: jaw crusher is mainly used for crushing large bulk mineral materials into small pieces so as to finely grind by ball mill. it is widely used to crush all kinds of ores and bulk material. the equipment mainly applied to crush materials in rough, medium and fine scale such as ore limestone, calcium carbides, carbide slag, shale, basalt.

Lastly, because a large part of the calcium carbide slag does not enter the mill and directly enters the finished product chute, the steel ball gradation of the mill needs to be adjusted. the maximum diameter of the steel ball used is φ80 and the minimum φ30, in which the coarse grinder uses φ80, φ70, φ60, φ50, and the fine grinder uses.
