Sulfur powder is a flammable and explosive material, so it has the same problem-burning explosion danger when other flammable and explosive materials are crushed. The sulfur crushing industry often generates combustion and explosion, and the explosion accident brings great loss to personnel and equipment. Moreover, when the sulfur is crushed, a large amount of static electricity is generated, which is not only one of the factors of combustion and explosion, but also causes difficulty in ash removal and blanking due to the agglomeration and adsorption of the static electricity. At present, domestic equipment for crushing inflammable and explosive materials has no method for well solving the problems encountered in sulfur crushing, and as the crushing of the inflammable and explosive materials mostly relates to the military field, the research results in the aspect are less disclosed abroad.
Because the sulfur powder is a flammable and explosive material, combustion and explosion often occur in the processing production and processing of the sulfur crushing industry, a large amount of static electricity is generated during the sulfur crushing, the static electricity is not only one of the factors of combustion and explosion, and the dust removal and blanking are difficult due to the aggregation and adsorption of the static electricity. At present, the existing equipment for crushing flammable and combustible materials in China has no way to well solve the problems encountered in crushing dangerous materials, and the existing domestic equipment for crushing flammable and combustible products is not suitable for processing wet-type crushed sulfur, so that the production bottleneck of a safe sulfur crushing technology is still the bottleneck.
