Sulfur powder is an important chemical raw material. The fertilizer industry is the largest user of sulfur. Other uses of sulfur include explosives, steel pickling, pharmaceutical and food industries, etc. We should all know that sulfur powder is classified as chemical drugs, so we assume during screening Inhaling too much will have a certain impact on the physical condition of the staff. The production and processing methods of sulfur powder are as follows:
The sulfur powder is placed in the air flow screen body. The air flow screen abandons the traditional gravity potential energy operating principle and opens up a new screening method of kinetic work of the carrier fluid. The screened sulfur powder is mixed with the air flow through the spiral conveying system, and then enters the In the mesh cylinder, the sulfur powder is pushed by centrifugal force and cyclone when passing through the wind wheel blades in the mesh cylinder, and then the sulfur powder can be sprayed through the mesh, and finally discharged from the fine material discharge port, while the sulfur powder that cannot pass through the mesh is along the wall of the mesh cylinder. Discharge from the coarse material discharge port.
It uses high-speed airflow as a carrier in a closed state to spray the fully dispersed sulfur powder towards the screen with sufficient kinetic energy to achieve the purpose of rapid classification. Therefore, the air flow screen has large output, high efficiency, non-stick mesh, no blocking of mesh holes, and precise fineness.
In industry, sulfur, hydrogen sulfide, and sulfur dioxide are mainly used as raw materials, among which sulfur is the most common. In industry, sulfur mainly comes from two sources: one is extracted from sulfur ores; the other is recovered from desulfurization devices in natural gas, petroleum processing and other industries. The purity of raw sulfur must meet the requirements, otherwise the product quality will be seriously affected.
According to different classification methods, insoluble sulfur has a variety of production processes. Different processes basically include raw material pretreatment, pre-melting, polymerization, quenching, solidification, extraction, oil filling and other processes.
