2. Gypsum is transported from the stock yard to the crusher by the belt conveyor, and the crusher is responsible for crushing gypsum mine, including the tailings filtered out.
3. The gypsum materials crushed by the crusher enter the vibrating screen for screening, and the materials that cannot pass through the screen re-enter the crusher for crushing again.
4. The gypsum material screened by the sieve is dried first, and the dried gypsum material is sent to a calciner for calcination through a conveyor belt, and the free water and part of crystal water in the gypsum are removed by using the high temperature in the furnace.
5. Gypsum powder enters the fluidized bed, and under the action of the fluidized bed, the fluidized state is completed, and the graded calcination is completed through overflow, and finally gypsum meeting the needs of various industries is obtained.
