Potassium Feldspar Uses And Processing Production2021-08-06

What is Potassium Feldspar

Feldspar group minerals containing some of the alkali metal aluminum silicate mineral, feldspar belong to one of the most common feldspar group minerals, belongs to monoclinic system, usually rendered meat red, yellow, white and other colors; According to its density, hardness and composition and characteristics of the contained potassium, feldspar powder has a wide range of application in glass, porcelain and other industrial manufacturing and preparation of potash.

Usage of Potassium Feldspar

1Feldspar powder is the main raw material for the glass industry, accounting for about 50%-60% of the total amount; in addition, accounted for 30% of the amount in ceramic industry, and other applications in chemical, glass flux, ceramic body materials, ceramic glaze, enamel raw materials, abrasives, fiberglass, welding industries.

1. One Of The Purposes: Glass Flux

The iron contained in feldspar is relatively low, easy melting than alumina, relatively speaking, K-feldspar melting temperature is low and broad category, it is often used to increase the glass batch alumina content, thereby reduce the amount of alkali in the manufacturing process of glass.

2. The Second Purpose: The Ceramic Body Ingredients

Feldspar used as ceramic body ingredients, can reduce shrinkage or deformation occurs due to drying, thereby improving the drying performance and shorten the drying time of the ceramic.

3. The Third Purpose: Other Raw Materials

Feldspar can also mixed with other mineral material for making enamel, also a most common painting in enameled material. Rich in potassium feldspar contained, it can also be used as raw material to extract potash.

Potassium Feldspar Powder Processing Technological Process

Phrase One: Raw Material Crushing

Feldspar blocks will be crushed to 15mm-50mm fineness by crusher.

Phrase Two: Grinding

Crushed feldspar material will be sent to the storage hopper by the elevator, and then the feeder will send the material to the main mill for grinding.

Phrase Three: Classifying

Ground material will be classified, coarse powder will fall back to the main mill to be ground again.

Phase Four: Production Collecting

Qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
