1 Products
The expanded perlite perlite ore preheated instantaneous high temperature roasting expansion made an internal honeycomb structure white granular material. Principle: the formation of a certain size ore perlite ore by crushing, pre-heat roasting, rapid heating (1000 ℃) ore moisture vaporization in the vitreous of ore containing softening internal expansion, forming a porous structure, 10-30 times the volume expansion of non-metallic mineral products. perlite technology in accordance with its expansion and for different purposes are divided into three types: open hole (open cell), closed-cell (closed cell), the hollow hole (balloon).
2 Production conditions
