The characteristics of sulfur: sulfur alias sulfur, colloidal sulfur, sulfur block. Appearance is light yellow brittle crystal or powder with special odor. The molecular weight is 32.06, the vapor pressure is 0.13kPa, the flash point is 207°C, the melting point is 119°C, the boiling point is 444.6°C, and the relative density (water=1) is 2.0. Sulfur is insoluble in water, slightly soluble in alcohol and ether, and easily soluble in carbon disulfide.
Sulfur Uses:
As a flammable solid, sulfur is mainly used in the manufacture of dyes, pesticides, matches, gunpowder, rubber, rayon, etc.
Equipment selection:
Sulfur burns in the air, a blue flame occurs when burning, and sulfur dioxide is formed. The powder is easy to burn and even explode when mixed with air or oxidant. According to the characteristics of the material, the inert gas is used to protect the high-efficiency impact mill.
working principle:
High-efficiency impact mill under inert gas protection is based on ordinary high-efficiency impact mill and vertical turbine high-precision classifier. It is designed and developed for flammable, explosive, oxidizable and other materials. The whole system of the equipment adopts inert gas as the fluid working medium, and the complete set of equipment consists of inert gas source, oxygen content tester, intake pipeline system, closed-circuit feeding system, vertical turbine classifier, induced draft fan, closed-displacement discharge valve, anti-static It is composed of a pulse reverse air blowing dust collector, an inert gas supplementary device, etc. The outlet of the induced draft fan is connected to the air inlet of the high-efficiency impact mill to form a closed circulation system of inert gas.
Performance characteristics: The entire production line is operated in a fully enclosed negative pressure cycle, and PLC programming control is adopted to minimize human operation and control factors. The control cabinet can be placed in a separate control room in the distance. The packaging and discharging use an automatic packaging machine. Monitoring probe, can be completely unmanned
Equipment composition:
Inert gas shielding airflow crushing classifier is to add inert gas (nitrogen, argon, carbon dioxide, etc.) as a medium to achieve closed-circuit crushing when crushing flammable, explosive, and oxidizable materials. It is composed of cleaning system, crushing system, classification system, collection system, feeding and discharging system, nitrogen purity test supplementary system, nitrogen production system and electrical control system. It has been widely used in the processing of metal powder, oxidizable raw materials and flammable and explosive materials.
