Feldspar is the most important rock forming mineral in surface rocks. Feldspar is the general name of feldspar minerals. It is a common aluminosilicate rock forming mineral containing calcium, sodium and potassium.
Feldspar is an aluminosilicate mineral containing calcium, sodium and potassium. It has many kinds, such as albite, anorthite, barium feldspar, barium ice feldspar, microcline, orthoclase, diorthite, etc. They all have glass luster and a variety of colors. There are colorless, white, yellow, pink, green, gray, black, etc. Some transparent, some translucent. Feldspar itself should be colorless and transparent. The reason why it is colored or not completely transparent is because it contains other impurities. Some are in block shape, some in plate shape, some in column shape or needle shape, etc.
Feldspar rich in potassium or sodium is mainly used in ceramic industry, glass industry and enamel industry. Feldspar containing rare elements such as rubidium and cesium can be used as mineral raw materials for extracting these elements. Feldspar with beautiful color can be used as decorative stone and inferior gem.
Feldspar accounts for up to 60% in the earth’s crust and can appear in igneous, metamorphic and sedimentary rocks. Feldspar is the main mineral component of almost all igneous rocks, which is of great significance for rock classification. There are other drugs of the same name.

Feldspar grinding process flow
Stage I: crushing
Large feldspar materials are crushed by the crusher to the feed fineness (less than 30mm) that can enter the pulverizer.
Stage 2: material grinding
The crushed small feldspar materials are sent to the raw material bin by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the vibrating feeder for grinding. After grinding, the milled materials are graded by the analyzer. Those whose fineness meets the specification flow into the large cyclone collector with the wind, and then discharged into finished products through the discharge valve. Those whose fineness is unqualified cannot be screened by the analyzer, but still fall back to the host for re grinding.
Stage III: storage or packaging of finished products in cans
① The finished products discharged from the discharge valve are transported to the finished product tank for storage by pneumatic conveying equipment.
② The finished products discharged from the discharge valve are packaged by a double mouth packaging machine.
③ The finished products discharged from the discharge valve are packaged by the ton baler.
