        When heating and calcining the dehydrate gypsum and chemical gypsum (ardealite, desulphurization plaster, fluorgypsum), the dehydrate gypsum was decomposed, we get the semi-hydrated gypsum, i.e., plaster of Paris.According to the temperature and pressure during decomposition, the products include high intensity gypsum and plaster of Paris.They are the same in the process of mechanization manufacture the plaster of Paris. The plaster breaking system, calcined system and grinding aging system are the main parts.The roller breaking machine and so on can be used as the breaking equipment.The continued and discontinued revolving kiln, continued and discontinued vertical pot, heat-conductive oil boiler or drying machine can be used as the cacined equipment.The calcined process: one is grinding after fired, the other is fired after grinding.We can choose Romans mill, vertical mill, peters mill as the grinding equipment.The whole process is as following:Gypsum ----- homogenization ---- rough breaking --- detailed breaking ----Measurement (calculating) ----calcined (oil coal, dust-collector)---- homogenization(dust-collector)----grinding(dust-collector)---aging (dust-collector)----- packing

        The whole process of gypsum block consists of gypsum powder construction and block preparation. The influence on environment mainly lies in gypsum powder construction. The powder dust, cinder and smoke discharged by it are very smaller in comparison with other building materials; therefore, it will be enough to take general controlling measure. The gypsum block is used in unloading inner partition. It does no harm to human health since it has much contact with human. For it discharges no harmful gases and no radioactive heavy, heat preservation and heat insulation, it is typically one kind of green building materials.The gypsum block machines consist of preparation system, mixing machine, central hydraulic station, space distance and PLC electric control device. By adopting the advanced vertical hydraulic emission technology and PLC electric control device, the whole process can be fully automatic, high output, high precision. The raw material is: architectural gypsum powder and water.Picture illustration:The upper one is the delivery parts, the right upper one is drying parts, the lower one is shaping parts.The quality of our products conforms to the construction standard of gypsum powder JC/T698—1998  

        The gypsum board is anti-pressure, fire-resistant, insulated, light, poisonous, little pollution, adjusting the humidity of the room; it is widely used in the construction and decoration industry. With the development of social progress and improvement in people 's consumption level, the newly green materials substituted for wood are accepted by the people home and aboard.According to the production flow, the gypsum board production line DCS monitor system can be divided into five parts: preparation shaping machine, centralized control, auto board-enter, auto board-exit and kiln temperature Control.Preparation shaping machine: gypsum powder screw conveyer, thick pastes pump, vesicant metering pumps, feeding screw conveyer, slurry mixer, forming station mixer, platform shaking machine and ring belt forming machine. By adopting the computer control system, the gypsum powder, foaming agent and slurry can be mixed in a scientific way. The process is high precise, easy to operate, energy saving.Centralized control system: the general control can deal with the data acquisition and processing, at the same time; monitor the shaping process and drying process. With the support of powerful database, together with humidity and temperature also other recorded parameter, we can materialize scientific management. The computer interface is friendly, easy to operate; all parameters can be known at the first glance. The preparation, shaping, drying process is highly automatic, even the beginner can operate it.Auto board-enter system: auto board cutter, belt conveyor, roller, board turnover machine, kiln enter distributor, faster board-enter and other equipment, through PLC auto control, the process of cutter, speed-up, kiln enter of gypsum board is finished. Automatic Finished board system: It includes Board-exit from dryer, layer-distributor, horizontal belt conveyor, roller, cutter and stacking machine. All of them are done by central control system through sensor, PLC, touch screen and control panels. Cutting, taping and stacking are finished automatically. The system has the functional such as Data amendment, productivity inquiry, and real time event alarm and status inquiry. Drive, temperature control, and hot air cycling system: This system is controlled through remote meter and humidity sensor. Heating conveyor and hot air cycling are control by computer. Using inverter makes the drying accurate and saving energy. The production of gypsum board, not only has a potential market, but also adopts to the International trend.

        Gypsum slurry is made up from plaster of Paris (calcined gypsum powder), water and other additives, such as starch, foaming agent, in a continuous mixer. This slurry spreads from spouts of mixer onto a moving sheet of paper. Gypsum board formed through panel extrusion forming machine with back-front two layers paper. Once formed, the gypsum board moves on a shaping belt. During this journey, the plaster core has time to set, or harden. And the required product information is printed on the back of the boards via an ink jet printer. Then the board is cut as specific length. The cut board are then turned over and passed into multiple layers drying kiln.the drying kiln heated through heating system(boiler). the more popular type is heating oil conductive.  Generally it takes 90mins for drying. After that, the board exits and turns over again. After the boards have dried, they are trimmed and stacked to form pallets. Here, finish the whole production. Finished products are loaded for market
