Potash feldspar is a kind of feldspathic mineral. It is a potassium-rich silicate mineral. It is also a non-water soluble potassium resource with high potassium content, widest distribution, and largest reserves. The chemical structure of K-feldspar is extremely stable. Its melting temperature is 1100-1200 degrees Celsius. The melting interval is longer. It has strong solubility. It melts at high temperatures to form glass. The substance is transparent, so it is widely used in glass and ceramics, potash fertilizer and other industrial fields. In addition, the better quality of potassium feldspar is also commonly used in the manufacture of television glass bulbs.

Stage 1: Breaking

The potassium feldspar bulk material is broken by a crusher to a fineness (≤20mm) that can enter the mill.

Stage 2: Grinding

The broken small pieces of potassium feldspar are sent to the silo via a lifting machine, and then evenly and quantitatively sent to the grinding chamber of the mill via a vibrating feeder for grinding.

Stage 3: Grading

After grinding, the material is graded by a separator. Unqualified powder is graded by the separator and returned to the host for re-grinding.

Stage 4: Collecting powder

The powder with fineness follows the air flow and enters the dust collector for separation and collection. The collected finished powder is sent from the conveying device to the finished product silo through the discharge port, and then is uniformly packed with powder tankers or automatic balers.
