What is potash feldspar
Potassium feldspar, usually called orthoclase, is red, yellow, white and other colors. It belongs to the monoclinic crystal system and has a Mohs hardness of 6. It is a water-insoluble potassium resource with high potassium content, wide distribution and large reserves. Potash feldspar has the characteristics of low melting point (1150±20°C), long melting interval, and high melting viscosity. It can be divided into orthoclase, plagioclase, and streak feldspar series.
Uses of potash feldspar
Potash feldspar is widely used in industrial sectors such as ceramic blanks, ceramic glazes, glass, electric porcelain, abrasive materials, and potash fertilizers. Potash feldspar in the glass industry, about 50-60% of potash feldspar is used as a raw material for the glass industry. In addition, the ceramic industry uses 30% of the potash feldspar, and the rest is widely used in chemicals, glass fluxes, Ceramic body ingredients, ceramic glaze, enamel raw materials, abrasives, glass fiber, welding rod and other industries.

1. Crush raw materials
The potash feldspar bulk material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.
2. Milling
The crushed small pieces of potassium feldspar are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.
3. Classification
The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.
4. Collection of finished products
The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
Analysis of various mills

Large-scale equipment and high output can meet large-scale production. The product has a high degree of sphericalization and better quality, but the equipment investment cost is higher. |
For the large-scale production of ultra-fine powders above 600 mesh, or customers have higher requirements for the particle shape of the powder, the HLMX ultra-fine vertical mill is the better choice. |

For ultra-fine powders above 600 mesh, the ultra-fine ring roller mill is a highly efficient, energy-saving, economical and practical milling equipment. |
Low investment cost, high output, low energy consumption, stable equipment, low noise; disadvantages: single machine output is degraded, and equipment large-scale is limited. |
