Perlite filter aid is selected ore pellets purified by gas heating, the selective expansion in the vertical shaft kiln, the expansion obtained by grinding clean with a certain size of the powder products, color white, the product bulk density of 230 ~ 460kg / m3. Product variety by the bulk density, grain size match, select the expansion of the formation of different pore diameter as a standard. 
 The soil and other bath products and silica filter aid, compared with harmful metals, non-metallic components less light in weight, filter fast, and good filtering effect. 
 This product has been widely used in beer and beverage industry, pharmaceutical industry, paint industry, oil industry and other production practices in the rapid filtration; such as biological chemistry, plant enzymes, citric acid plant, titanium dioxide plant, agar factory, Carla Rubber Factory, Starch Factory, caramel factory, brewery, monosodium glutamate factory, any industry can use the filter to use. 
 Production Introduction Perlite filter aid and the general characteristics of the use of 
 Process Description: ore grading --- Dry --- --- --- calcined feed / cooling molten --- --- --- smash multi-level winds to the grain selection --- Select --- - - bagging. 
 Description: Expanded perlite grinding through the air after election, many levels are carefully grinding gently uneven surface of the particles, the filter cake to each other extrusion molding process, the final product surface is jagged, they will join another bite the formation of coarse filter gap, many of which are within the Unicom Road, small enough to block the micron-sized particles, but also has 80% --- 90% of the porosity, to retain a higher continuous penetration. 
 My company is a perlite filter aid particles by the inert amorphous glass of white powder. The main ingredients are potassium, sodium, aluminum silicate. Itself does not contain organic matter, the production process to achieve sterilization by high temperature combustion, the packing density is 20% lighter than the diatomaceous earth. 
 GK - 110 perlite filter aid particles are very irregular in all curly sheet to form a filter cake when the 80% - 90% porosity, the pores of the particles have many similarities, so you can quickly filter and to 1 micron capture the ultra small particles. The special advantages of perlite filter media to maintain a high fluid flow rate in the retention of solid at the same time, its excellent chemical stability and no potential pollutants, the heavy metal ion content in general 0.005ppm, so can be used for food-grade filter.
