In the production process of industrial sulfur powder, static electricity is generated due to the friction of ball milling equipment, the friction of sulfur powder parts and equipment problems. When the concentration of sulfur powder in the air is too high, more static electricity is generated during production, which may lead to risks. Dust explosions caused by industrial sulphur powder can cause severe personnel and equipment losses.
In order to avoid and reduce the risks in the production of industrial sulphur powder, it is very necessary to deal with static electricity problems in the process of crushing and collecting sulphur
Due to the ionization of the air and the contact, collision and friction between the particles, the dust particles are charged, which may form a positive charge or a negative charge. Sulfur is a poor conductor of electricity and has high resistance, which is easy to form static electricity accumulation, and there is a hidden danger in production safety without a channel for static electricity accumulation.
The static electricity of sulfur dust is related to the particle size of the dust, the grinding time, and the grinding method, as well as the temperature and humidity of the production environment. Study the relationship between temperature and humidity, particle size of sulfur pulverization, time for pulverizing sulfur, frequency of vibration and crushing, etc. and the generation of static electricity, and master the basic electrostatic characteristics of sulfur dust, which has important guiding significance for electrostatic prevention and electrostatic control of dust. .
Specifically, the smaller the particle size of the industrial sulfur powder, the greater the static electricity per unit mass generated. This is because the smaller the particle size, the greater the surface area, the greater the chance of friction in contact with the grinding equipment, and therefore the more likely it is to generate electrostatic charges. This is why the smaller the particle size of the dust in the sulfur powder manufacturer, the easier it is to generate static sparks and the more likely to cause accidents.
