In recent years, with the development of glass and ceramic industries, the products are increasingly high-grade, and I over the demand for high-purity subway potassium feldspar is also increasing. Potassium feldspar is rich in resources, but contains iron and carbon beyond the standard, therefore, potassium feldspar in addition to iron is the key to purification, then it is necessary to first grind potassium feldspar, and for the grinding of potassium feldspar we can use the vertical grinding mill.
Potassium feldspar vertical grinding mill working principle
After calcination, the potassium feldspar is put into the fine crushing equipment, and after crushing, it enters the reserve bin through the bucket elevator, and then is conveyed to the main machine of the vertical mill through the electromagnetic vibrating feeder for grinding processing, the potassium feldspar moves evenly from the center to the edge of the grinding disc, and when it passes through the grinding roller channel area on the grinding disc, it is crushed by the grinding roller, and the large pieces of material are crushed directly, and the fine particles are squeezed to form the material bed for Intergranular crushing. The crushed material continues to move to the edge of the grinding disc until it is taken away by the strong airflow at the wind ring, while the larger granular material falls back to the grinding disc and continues to be crushed.
