Properties 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.
Equipment selection:
Sulfur burns in the air, a blue flame occurs when burning, and sulfur dioxide is formed. The powder is easily combusted or even exploded 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. The whole 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 and an inert gas supplementary device. The outlet of the induced draft fan is connected to the 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. Automatic packaging machines are used for packaging and discharging, and monitoring probes are used for on-site observation. Can be completely unmanned.
Equipment composition:
ZJ series inert gas shielding jet crushing classifier is to add inert gas (nitrogen, argon, carbon dioxide, etc.) as medium to realize closed-circuit crushing when crushing flammable, explosive and oxidizable materials. It consists of nitrogen filtration 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.
Scope of application:
It is used in metal powders, oxidizable raw materials, flammable and explosive raw materials, pharmaceutical ultrafine powders and other industries and raw materials that require inert gas protection. Typical materials are: fine spherical aluminum powder, selenium powder, carbonyl iron powder, cobalt powder, tungsten powder, magnesium powder, nickel powder, tantalum powder, etc.
