摘要
In dry acetylene generator, or to increase the byproduct reaction of acetylene polymerization such, without adversely affecting the yield and also not to invite Zocho risks for security due to the reaction temperature increases, the calcium carbide particle production method I provide. Calcium carbide method of greater than or equal to the particle diameter 4mm or less 5wt% and the particle size of 0.15mm or less to produce a 20wt% or less of calcium carbide grains, and a step A of pulverizing the calcium carbide in the crusher, it is pulverized by a pulverizer The comprises a step B of MeHiraki is applied to 4mm sieve, and a step C of introducing the remaining calcium carbide on the sieve again to the mill. Said step A~C is carried out in an inert gas atmosphere. The calcium carbide amount a to be introduced to the grinding machine in the step A, the calcium carbide content b having passed through the sieve in the step B is such that (a-b) /b=1~2.5, the grinding It wants to control the grinding particle size by machine.
