Product description: perlite filter aid is to purify the gas heating by the selection of small particle size of ores by selective expansion in the vertical shaft kiln expansion obtained by grinding purification of a certain size with a powder product, color white, the product bulk density 230 ~ 460kg/m3. Product varieties by bulk density, grain size, with a select different expansion of the formation of pore diameter as a standard. 



 This product is compared with the silicon bath soil, such as filter aid, with harmful metals, non-metallic composition, light weight, fast filter, filter effects, advantages. 



 This product has been widely used in rapid filtration of the beer and beverage industry, pharmaceutical industry, paint and coatings industry, oil industry production practice. 



 Perlite filter aid production process Introduction and general usage characteristics 



 Process description: ore --- grading --- Drying --- feeding --- calcined / melt --- cooling --- crushing --- winnowing --- Featured --- tablets - - bagging. 


 Description: winnowing the perlite puffed and then after the grinding, carefully grade gently grinding the particle surface uneven cake molding process in order to squeeze each other, the final product surface is jagged, they will bite each connection coarse filter gap, many of which are within Unicom Road, small micron size particles can stop, but also has a 80% --- 90% of the porosity, retained a higher continuous penetration. 

 I perlite filter aid is a white powder consisting of an inert amorphous glass particles. The main ingredients are potassium, sodium, aluminum silicate. Itself does not contain organic matter, the production process can be sterilized by high temperature combustion, the packing density than the diatomaceous earth is 20% lighter. 


 GK - 110 perlite filter aid particles is very irregular curly flakes form a filter cake of 80% - 90% porosity, the particles have many pores interlinked, so you can quickly filter and to capture the ultra-small particles below 1 micron. The special advantage of perlite filter media interception solid to maintain a high liquid flow rate at the same time, its excellent chemical stability and there is a potential pollutant, its heavy metal ion content of 0.005% can be used for food-grade filter.
