In the production of potassium feldspar powder in a potassium feldspar concentrator in Quanzhou, Fujian Province, the technology is that the slag and water are separated by the screw separator, but the water content of the finished product is too high to dry the pile. Later, after investigation and experiments, the vibrating dehydration screen of our company was selected to replace the spiral separator. The finished potassium feldspar was dehydrated by the vibrating dehydration screen and the moisture content was 20%, so that the dry pile effect was achieved. In addition, the fine sand that was lost when using spiral separator was selected, so that the recovery rate of finished product was increased, and the economic benefit of high clothes dehydration screen was far higher than that of the original spiral separator.

A vanadium mine in Shangluo, 500t/d vanadium tailings, with a concentration of 25%, the grain size is about 70% of the 100 mesh, and more than 95% of the dry ore can be extracted with dry row sieve. The tailings of the tailings after dry row are less than 20%. tailings, and the tailings are used for building materials and the tailings are reused; the bottom current can be returned to water resources directly, and the tailings are not used completely.

The production process of magnetic materials is complex, and it is inevitable that there will be caking, industrial impurities and secondary pollutants entering into the raw materials, which will affect the quality. Therefore, the final screening must be carried out. Due to its high hardness, high viscosity, easy to clasp and easy to fly, it is difficult to solve the screening problem in the production process. The engineers of the north mine have also made many experiments, using vibrating screens, ultrasonic screens, or equipment using air separation and similar airflow sieves. Only rough screening is carried out, and screening is very difficult to carry out effectively. Not only is the output low and the particle size exceeding the standard, And still dust flies, pollution is serious.
