Problems solved by technology
During the production process, both the crystal turning equipment and the drying equipment need to separately provide heat for a long time, which consumes a lot of energy in the whole process, and a lot of heat in each equipment is wasted with exhaust gas, which increases energy consumption
During the transfer of production materials, some equipment stops working, but in order to ensure the subsequent use of equipment, heat is often supplied continuously, which causes energy waste

Description
technical field [0001] The invention relates to the technical field of alpha gypsum preparation, and more specifically relates to a continuous preparation system for alpha gypsum. Background technique [0002] α-gypsum is α-type hemihydrate gypsum, which is a kind of high-strength gypsum. It has the advantages of high strength, high density, high hardness, and high flow. It is widely used in the fields of molds, precision manufacturing, and building materials. α gypsum is natural or industrial gypsum under the action of a crystal modifier, undergoes crystal changes under a certain pressure and temperature, and dehydrates to form α gypsum containing 1 / 2 crystal water. [0003] Autoclaving is a relatively common production process used in the production of α gypsum. Autoclave production is to mix the dihydrate gypsum raw material and the crystal transformation agent into a stocker with good air permeability, send the stocker into the crystal transformation equipment, and inje...
