gypsum powder production machinery equipment


Gypsum powder plant

30,000 ton/year~240,000 ton/year


fully automatic

Calcination system

1.using boiling furnace to calcine

2.adopting heat conductive oil furnace as heat source


coal, natural gas, heavy oil, diesel oil

Main materials

natural gypsum rock, desulfurization gypsum, dephosphorizaiton gypsum

Standard of product quality

In conformity with national standard “GB/T 9776-2008 construction gypsum“

1. Crushed process flow introduction

Crusher breaks up large sized gypsum ore to small granule less 25mm. and then, separator mil the granule to powder with required fitness and deliver to boiling furnace to calcine. The calcined gypsum powder is delivered to grog bin for saving or production workshop for producing.

2.Boiling furnace process flow introduction

(1) Working theory

the main part of boiling furnace is composed of thin and dense radiator pipes, which is filled with conduction oil to release the heat to the inside of the furnace.

Equipped at the bottom of the furnace, the roots blower makes the powder inside the furnace into the boiled state. The powder material backed and dehydrated with crystallization water at certain temperature, flow out through the outlet automatically.

The gypsum powder produced by this procedure has stable quality and well controlled crystallization water rate, initial and final set time. Further more, by using dry electrostatic cleaner, the equipment has over 95% dust collection efficiency and eliminate the dust pollution.

(2) Simple and sustainable structure

Because of the fluidization material, funace doesn't need rotatable component so that it easy to built and almost free of maintenance. thanks to the low temperature heat source, the furnace won't be damaged by over heating and has longer operating life.

(3) Compact design and less space requirement

With vertical arrangement, the dust catcher on the top of the furnace body is integrated with the boiling furnace compactly. The system not only less space but also avoids condensation of the dust catcher.

(4) Low energy consumption

The heat energy, passed form the heat source to the material, is almost all used for material's dehydration, except a small part is used to heat the cold air blew form the bottom of the heating furnace radiated form the furnace body. Since the boiling furnace uses twice heat source, the final heat efficiency should be boiler's heat efficiency ride stove's heat efficiency. the steam boilers or hot oil boilers are boilers, efficiency can reach 60-70% and the tot oil boiler's can reach 70-80%.(our company uses organic heat carrier hot oil boiler.) with steam, it can reach 57-67%,it can reach 67-76%.

(5)Good quality, ideal composition of Paris, stable physical

Property due to the low temperature heat source, the plaster does not tend to be over calcined. Only if controlling the discharte gypsum and with less than 5% anhydrite. And the spare is all hemihydrates gypsum. This composition is very ideal and with stable physical property.
