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.
For 80-400 mesh Potash feldspar powder, Guilin hengda HD series high efficiency Potash feldspar raymond grinding mill is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
HD series high efficiency raymond grinding mill specifications:
Max feeding size: ≤35mm
Main motor power：45-315KW
Final product size: 80-400 mesh
Applications : For non-metallic minerals with a Mohs hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, , zircon sand, bentonite and other non-metallic minerals.
