Product introduction:

The powder product with certain particle size is obtained by selecting small particle size ore, heating by purified gas, selective expansion in vertical shaft kiln, expansion and grinding purification.

Main features:

The product is white, tasteless and non-toxic. According to the volume weight, particle size and pore diameter formed by expansion, it can be divided into three varieties: fast, medium and slow.

Brief introduction of production process and general use characteristics of perlite filter aid: ore → classification → drying → feeding → calcination → cooling → crushing → air separation → cleaning → granulation → bagging;

Usage characteristics:

After expansion, perlite is ground and air selected, and many grades are carefully selected, and then gently ground to make the surface of particles uneven. The final product surface is serrated, so that the filter cake can be squeezed each other in the forming process. They will occlude and connect with each other to form rough filter gaps, in which there are many inline channels, which are small enough to block micron sized particles, but at the same time, they have 80% - 90% porosity, High continuous permeability is retained.

The advantages of our perlite filter aid are as follows:

The product produced by our company is a kind of white solid powder composed of inert amorphous glass particles. The main components are potassium, sodium, aluminosilicate. It does not contain organic matter. It can be sterilized by high temperature combustion in the production process. The bulk density is 20% lighter than diatomite;

Each particle of perlite filter aid is very irregular and curly. When the filter cake is formed, it has 80% - 90% porosity, and each particle has many pores. Therefore, it can quickly filter and capture the submicron particles below 1 micron.
