Gypsum powder production line introduction :

In order to achieve the above mentioned requirements, our company research and develop a whole set of production and processing technology of ebullience calciner. The main materials for the ebullience calciner is using high-quality steel. For example, coil pipe adopts seamless steel tube steel plate is mainly using the carbon steel and HSLA steel plate,the international product is used to the frame somatotype steel. In additional, in order to guarantee the welding quality, the operator people must be certified for post. After the welding is completed, in order to avoid the leakage of heat transfer oil, the pressure of the water in the main coil pipe should be tested. If the pressure of product is up to 0.5-1.6M Pa and packing more than half an hour without leakage is considered to be qualified product.

The main working principle of the ebullience calciner drying system: the main part of the ebullience calciner is formed by the small-diameter cooling coil pipes. The heat transfer oil is piped into coil pipe and releases heat into the internal of furnace after exchanging heat. Roots blower which can blow the cold wind into the furnace by air distribution plate is equipped at the bottom part of the ebullience calciner, by blowing let the powder in  furnace boiling. And under certain temperature, the powder which has been dried and without crystallization water becomes light, so it can flow to the outlet automatically. The quality of the gypsum powder produced in this way is stable and the content of crystallization water is large, so it is easy to control the time of solidification. In addition, the dry electrostatic precipitator was equipped to this machine, the efficiency of dust removal can reach more than 95% after the dust removal, eliminating the dust pollution.
