Application of Ultra-fine Vertical Micro-grinding in Sulfur Processing
Sulphur is sulfur and its molecular formula is S. It can be extracted from natural sulphur or heated pyrite. Sulfur is a yellow solid with both crystalline and amorphous forms. At present, the domestic market needs about 2 million tons of sulfur per year, of which, the domestically produced 800,000 tons, and the annual import of about 1.2 million tons. Mainly used in chemical, pharmaceutical, rubber, household chemicals and other industries. These sulphur have four particle conditions, one is massive, the other is granular, the third is powdery, and the fourth is flaky. Because sulphur is more flammable and there is a large risk of grinding operations, the current domestic use of powdered sulphur is around 200,000 tons. However, as the demand for quality improvement in various industries increases, the demand for sulphur powder increases and the demand for sulphur powder increases. The direction of development.
SBM ultrafine mill is a vertical structure, also known as vertical mill, consisting of transmission system, grinding system and body. The transmission system generally uses low-speed motor to directly reduce the speed of the belt pulley, and the transmission is stable and reliable. The grinding system consists of a roller device, a wear-resistant lining plate and a positioning device. The roller device is connected with the main shaft through a face plate and a pin shaft and is controlled by a positioning device so that the roller and the wear-resistant lining plate can be adjusted. gap. In operation, the transmission causes the main shaft to rotate so as to drive the grinding roller device to rotate synchronously. After the material enters the mill from the upper feed port, the spreader plate is evenly spread on the inner wall of the middle body, and the relative arm rotates with the arm outside the rocker under the action of gravity, thereby rolling the material and grinding the material from The lower discharge port discharges.
