1 Product Description
The product is perlite ore by crushing, screening from the original minerals, I can pearl sand into a variety of products manufactured according to customer needs.

2. Production process
Ore (crushing, drying) → coarse crushing crushing 20 mesh to 50 mesh (sieve) 21mm ~ 40mm (grated) → broken in 5mm (grinding and sieving) → → bagging → tailings> 50 mesh (sub level)

3 applications
(1) 8 to 12 mesh, 12 to 18 mesh, 18 to 20 mesh pearl sand through the expansion do heat insulation materials used in the construction sector;
(2) 20 to 50, 30 to 50 mesh pearl sand through the expansion as cast steel with coverage and hit slag agent or glass beads, and other insulation materials;
(3) 50 to 70 mesh pearl sand through the expansion as beer, pharmaceutical filter and oxygen cryogenic tank insulation.

4 composition (Content%)

Composition(Content%)		SiO₂72.93	TiO₂0.09	Al₂O₃12.31
		Fe₂O₃0.54	MnO 0.06	MgO 0.14
		K₂O 4.67	Na₂O 3.29	P₂O₅0.04
		CaO 1.00	Loss on ignition 4.94
The role of each component	SiO₂/Al₂O₃	Is the chemical composition of the lead the perlite when the temperature quickly soften and maintain a certain viscosity at high temperatures main
	Na₂O/K₂O	The increase of the ratio of the decrease in viscosity of perlite, can lead to high temperatures resulting in decreased the perlite softening point
	Fe₂O₃+FeO	Its content increase will lead to a lower expanding perlite multiples
