Description

 

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO₄·2H₂O. To make gypsum as construction material, calcination process is needed, and part crystal water will be removed from gypsum. The calcined gypsum's chemical formula is CaSO4· 1/2H2O.  It is widely used as raw material for gypsum board, plaster, cornice, school chalk, etc. 

 

The gypsum board production line is composed of crushing system,  grinding system, calcining system, energy supply system, conveying system, packing system and storage system. 

 

Working process of the production line

 

The basic process of making gypsum powder is:  gypsum rock -- crusher -- raw material silo -- grinder -- calcinor -- silo-- packing machine

Features of the gypsum powder production line

 

The calcination system is the key procedure of the production line. The vertical calcinor is used in the calcination system. The main body of the calcinor is composed of delicate and intensive radiation pipes, in which hot air goes.  Hot air is made inside the furnace by burning oil, natural gas, LPG or coal, and it circulates between the hot air furnace and the calcinor.  At the bottom of the calcinor is mounted a Roots blower, which blows the gypsum upwards through the space between the hot air pipes. The gypsum powder inside the calcinor is in a boiling state, so the calcinor is also called boiling furnace. Being heated, the gypsum powder becomes lighter and it goes out of the calcinor automatically. 

 

The advantages of this calcining system:

 

Simple structure, free of maintenance

Compact machine, occupy less space

More energy-saving

Gypsum with this system has better physical characteristics and the setting time is easy to control

Better dust collecting result.

Installation of the production line and training to the operators

 

Engineers and technicians from our company will be dispatched to the installation site to instruct the installation and commissioning work. The buyer shall supply welding workers and fitters to cooperate in the work of installation and commissioning.  During the installation and commissioning, the buyer's operators will be trained in respects of operating, trouble shooting and operation by the technicians and engineers. 

 

 the gypsum plaster machine, the advanced technological equipments, like boiling furnace and high-voltage electrostatic dust removing system, are adopted and they make the gypsum powder machine are both energy-saving and environment-friendly.

The gypsum machine capacity: 30, 000 tons to 200, 000 tons per year.
