Automatic wall plaster machine Characteristic Introduction

With the development and progress of gypsum industry, the demand for gypsum powder is increasing, and the quality of gypsum powder is getting higher and higher. In the whole production process, drying and dehydration is the key link, but also difficult. According to this situation, after years of research and exploration, we have developed a new generation of dewatering device suitable for various gypsum production needs - boiling furnace

Product Details

A fluidized bed boiler is a rectangular vessel with a porous gas distribution plate at the bottom. There is a vertical partition inside the furnace, which divides the furnace into two parts, and there are a number of heating tubes inside. At the top of the furnace is a bellows connected to the furnace.

The powder is filled into the furnace regularly, and the air is blown into the bottom of the furnace through the air distribution plate to realize the fluidization of the powder. The energy of the heat source (steam or hot oil) is transferred through the surface of the heater pipe

The material is quickly mixed in the bed so that the whole bed is almost at the same temperature, and despite the constant addition of raw gypsum, it is immediately mixed with hot gypsum powder to reach the same temperature (170 to 180 ° C).

The temperature is just within the temperature range between dehydration of gypsum and conversion to CaSO4 1/2H2O. As a result, the plaster begins to dehydrate rapidly. Most of the CaSO4 2H2O in the main furnace is converted to CaSO4 1/2H2O. When the material enters the furnace, the temperature rises to more than 180-180 ° C. The rest of the CaSO4 2H2O is converted to CaSO4 1/2H2O, and a small amount is converted to anhydrous gypsum. The material then spills out of the furnace
