Gypsum Powder Equipment Production Craft Introduction

1. Crushed process :

Crusher breaks up large sized gypsum ore to small granule less 25mm. And then, separator mill 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 to production workshop for producing.

2. Boiling furnace process flow introduction

1) Principle :

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, baked and dehydrated with crystallization water at certain temperature, flows 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

Owing to the fluidization of material, furnace doesn’t have rotatable component so that it‘s easy to be 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.
