Perlite is a glassy rock from the acid lava after volcanic eruption and rapid cooling.Perlite ore includes perlite, obsidian and pitchstone. The difference between them is that perlite has a circular arc-shaped crack due to condensation, its water content is 2~6%; pitchstone has a unique resin luster gloss, its water content is 6~10%; obsidian has glass gloss and conchoidal fracture, its water content is generally less than 2%.

 

After crushing into powder,perlite can be widely used in insulation materials, heat insulation materials, rubber, plastics, cables, paints, inks, adsorbents, filter aids, agriculture and other industries.

                                                                                                                

 

At present, China's perlite powder in the production process need to encounter dust pollution problems.

 

MTW series European type grinding mill is the latest generation of grinding equipment which launched by Kefid with international advanced technology and a number of independent patented technology.Compared with traditional raymond mill, ball mill and other equipment, MTW European type grinding mill adopts roller boost, bevel gear transmission and many other patented technology.At the same power, the capacity increased by 20%.

 

Kefid MTW European type grinding mill is equipped with the advanced dust collector, dust removal efficiency is of 99.9%. In the processing of perlite powder,it can solve dust pollution problem well.
