Gypsum Powder Production Line

1. Brief Introduction

The gypsum stone is crushed into granule less than 25mm with crusher.It’s stored in raw material silo,then conveyed into grinding mill to make gypsum powder.The powder is classified through a classifier. The qualified powder in required fineness shall be carried to the calciner, while the unqualified powder shall be returned to the grinding mill for furhter process. The calcined gypsum powder (it’s usually called Plaster of Paris) shall be stored in the finished product silo for preparation of plasterboard raw material.
