Synthetic Gypsum Plant

With suitable processes and devices, synthetic gypsum as industrial by-product can be a kind of cost-effective material, so that we’ve developed the synthetic gypsum plant. We offer synthetic gypsum plant turnkey project service, plant production power 30,000 t/year- 500,000 t/year. We also provide device customization service, including designing, manufacturing and upgrading. Services we also offer:

Material measurement and analysis; Plant design and construction; Device design, manufacturing and auditing; Plant installation and test-run; Personnel training; After service & maintenance. Production Processes

Synthetic gypsum production consists of a series of processes, including material handling and feeding, drying, calcining, grinding and milling, etc., as described below:

Features of Synthetic Gypsum Plant

Synthetic gypsum is an industrial by-product, containing over 10% of free water. Therefore we’ve improved processes according to our experiences: by pre-dry dihydrate gypsum first, then calcining using boiling furnace, we can get high qualified synthetic gypsum. Our plant also features:

New boiling furnace calcining process; Gypsum powder aging process in finished silo by turning-over, get powder homogenized and cooled-down, avoid re-calcining; Heat source: air heater using coal, gas (light oil) as fuel serves as heat source, using hot air as heat exchange medium, thermal efficiency > 85%;
Preheating utilization system is applied, leading exhaust gas to the outlet position, getting it mixed with the high temperature flue gas stroke, to effectively save energy; Using PLC, pressure transmitter and temperature electric regulation for furnace controlling. Outlet temperature of the system is controlled within the range of ±30℃. Products of the system features stable quality. Rigorous experiments and accurate experimental devices are performed and applied in every part of our production, including raw material tests, production process experiments, quality inspection before leaving the factory, etc. Dust removing system applies bag dust remover, the system is ensured running in negative pressure state. Waste gets discharged after being cleaned by dust removing.
