Introduction:

Gypsum is an important architectural material. We’ve been developing and manufacturing gypsum processing machinery since 1998. We offer a complete gypsum production line solution according to the location of your factory, plant area and market conditions. The capacity of our production line is from 20,000/ Year to 500,000 / year. We also offer replacement and upgrade services on devices in your plant. We provide worldwide services whenever you need.

Production Process:

Multiple processes are taken in production of the line. First, gypsum ores are being crushed, conveyed and stored into raw material bin, and then the crushed gypsum ores get grinded into powder with fineness required by the Raymond mill, and the gypsum powder is then conveyed into calcining section via metering feeding device to get calcined, and the calcined gypsum gets modified by grinder and cooled by cooling device. Finally, the finished gypsum is conveyed for storage.

Features of Our Gypsum Powder Production Line:

1>. A material supplement stabilizing system is deployed to achieve stable supplement of the fluidized bed combustion boiler, and to stabilize material supplement and heating. Material supplement stabilizing system consists of material supplement stabilizing bin and conveying device (metering screw or belt weigher).

2>. Calcining system applies hot air boiling furnace calcining process to perform even calcination on gypsum material.

3>. Cooling device added to cool down calcined gypsum before it enters silo, to prevent gypsum from deterioration caused by over temperature.

4>. Silo turn-over system: materials at different time periods feature different quality, therefore products made from them feature different quality. The silo turn-over system

can evenly mix new and old materials, make the products share the same quality. Besides, the system prevents overheating deterioration caused by heat generated by powder accumulation.

5>. The dust removal system applies a bag type dust collector, to ensure dust generated during pre-drying, conveying, grinding, calcination and aging processes get cleaned before discharging outside, to meet working environmental requirements.

6. Distributed control system is applied, to do centralized control on distributed devices.
