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.

HLM series vertical mill


HLMX series ultrafine vertical mill

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.

Hongcheng potash feldspar mill has a very high operating efficiency, reliable quality, and greatly improved efficiency. Since the purchase of the potash feldspar mill produced by Guilin Hongcheng, both in terms of production capacity and unit energy consumption All of the above have greatly improved the efficiency of users' equipment, and created better social and economic benefits for us. It is truly a new type of high-efficiency and energy-saving milling equipment.
