After calcination, potassium feldspar is formed into blocks, which are put into fine crushing equipment. After crushing, it enters the storage bin through a bucket elevator, and then is transported to the main machine of the vertical grinding mill for grinding through an electromagnetic vibrating feeder. The potassium feldspar moves evenly from the center of the grinding disc to the edge. When passing through the grinding roller area on the grinding disc, it is crushed by the grinding roller. Large pieces of material are directly crushed, and fine particles are squeezed to form a material bed for inter-particle crushing. The crushed material continues to move to the edge of the grinding disc until it is carried away by the strong airflow at the wind ring, and the larger particles fall back onto the grinding disc and continue to be crushed.

Potassium feldspar vertical grinding machine product advantages

1. Low investment cost. The equipment integrates crushing, drying, grinding, and grading and conveying. The system is simple, the layout is compact, the floor space is small, and it can be arranged outdoors, saving a lot of investment costs.
2. Easy operation and maintenance. (1) Equipped with an automatic control system, remote control can be realized, and the operation is simple. (2) Equipped with a limit device to prevent direct contact between the roller sleeve and the grinding disc lining, avoiding destructive impact and severe vibration. (3) By inspecting the oil cylinder, turning the boom, replacing the roller sleeve and lining is convenient and quick, reducing downtime losses.
3. Low operating cost. High efficiency: The grinding roller directly grinds and grinds the material on the grinding disc, reducing energy consumption and operating costs. Low wear: The grinding roller does not directly contact the grinding disc during operation. The grinding roller and lining are made of wear-resistant materials, with a long service life and less wear.
4. High drying efficiency. The hot air introduced into the mill from the outside directly and repeatedly contacts the powdered material in the mill, with strong drying capacity, which can save a dryer for the mill system and save energy. By adjusting the hot air temperature, it can meet the requirements of materials with different humidity.
5. Stable product quality. (1) Since the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, reduce repeated grinding, and stabilize product quality. (2) The product contains less iron, and the mechanical wear iron is easy to remove. When used for grinding white or transparent materials, the product has high whiteness and clarity.
6. Environmental protection and cleanliness. Small vibration, low noise, and the equipment is sealed as a whole. The system works under negative pressure, without dust spillage, clean environment, and meets national environmental protection requirements
