Problems solved by technology

[0003] Existing domestic gypsum products enterprises mostly use internal and external fired rotary kilns, intermittent or continuous frying pans, fluidized bed furnaces, etc., with small scale and unsound supporting facilities , the degree of automation is low, the product quality is not stable enough, the energy consumption is high, etc.
Moreover, the dehydration of gypsum in the existing calcination process is insufficient and uneven
In addition, the thermal efficiency of these devices is low

Abstract

The invention discloses a system for calcinating plaster and a calcinating method thereof. The system includes a crusher for crushing the plaster material, a plaster drying device for drying the crushed plaster material, an oscillating sieve for sieving the dried plaster material, a calcinatory of a fluid bed for calcinating the sieved plaster material, a storage tower for storing the calcinated plaster as well as a hot air boiler for providing a thermal source for the plaster drying device and the calcinatory of the fluid bed. By adopting the device which first dries and then calcinates in the invention greatly promotes the efficiency and improves the quality of calcinating; besides, by adopting the single storage tower to carry out cooling, the efficiency of the whole system is greatly improved; the crushing and sieving of the plaster material guarantees that the calcinatory of the fluid bed sufficiently calcinates the plaster material, thus facilitating the production quality.

Description

technical field [0001] The present invention relates to a system for calcining gypsum. Background technique [0002] Gypsum stone or industrial by-product gypsum exists in the form of calcium sulfate dihydrate, and the process of removing part of the crystal water to make calcium sulfate hemihydrate is gypsum calcination. [0003] Existing gypsum products enterprises in China mostly use internal and external fired rotary kilns, intermittent or continuous frying pans, fluidized fluidized furnaces, etc., with small scale, unsound supporting facilities, low degree of automation, unstable product quality, and high energy consumption, etc. . Moreover, the dehydration of gypsum in the existing calcination process is insufficient and uneven. Furthermore, the thermal efficiency of these devices is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a gypsum calcining system with energy saving, environmental protec...
