Feldspar is a general term for feldspar minerals. It is a common type of aluminosilicate rock-forming minerals containing calcium, sodium and potassium.
The limestone is fed into the bucket elevator and subsequently transported to the raw material warehouse for grinding.
After grinding, the finished products are gathered by powder concentrator, and then conveyed to a screw conveyor.
The finished products are transported to the storage warehouse, while the excess gas is filtered by the dust collector.
The whole system is equipped with three pulse dust collectors to guarantee that the whole system is free of dust leakage.
The system is outfitted with an intelligent PLC control cabinet and an upper computer.

Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar. The required particle size are 20-400mm block, 60 mesh, 80 mesh, 100 mesh, 120 mesh, 200 mesh and 325 mesh.
