        Introduction of Process and Equipment 2.1 Process
 2.1.1 Weighing Section
 2.1.1.1 Building Gypsum
 The gypsum in the   material storage house is sent to the weighing bin through a screw conveyor, and   the screw conveyor will stop when the amount of materials in the weighing bin   reaches the set value.
 2.1.1.2 Water
 The water of the plant pipe network   is sent to the weighing tank, which is controlled by the solenoid valve. When   the amount of water in the tank reaches the set value, the solenoid valve will   be closed. The water tank is fitted with a level gauge, and the required value   can be set through the DCS system.
 2.1.2 Forming Section
 The weighed   gypsum is quickly conveyed to the mixer by the screw conveyor, and water is   transported to the mixer via the pneumatic valve. After being mixed, the gypsum   slurry is dumped into the forming machine. When the gypsum slurry achieves   certain strength, a hydraulic scrapping device is used to scrape a rabbet and   then eject the formed gypsum block through hydraulic pressure. After this, the   two-dimensional space clamp is used to clamp the gypsum block from the forming   machine to the dryer.
 2.1.3 Drying Section
 The water of the formed   gypsum block can be removed by two methods: natural drying and artificial   drying.
 Our self-developed gypsum block dryer is a tunnel drying machine   which uses cross wind technology. The drying time is 36 hours. This dryer can   use many types of fuels, including coal, natural gas, diesel, heavy oil, etc.   Besides, it is equipped with pusher, waste heat recovery system, automatic wind   and temperature regulation system, steering machine, unloading machine, and   subsystem, which help realize automatic running of the dryer.
 2.1.4 Finished   Product Packaging and Storing Section
 The dried gypsum block is unloaded and   sent to the packaging machine through the unloading machine.
 2.3 Main   Equipment Introduction
 2.3.1 Gypsum Powder Weighing Bin
 It uses high   precision weighing sensor, resulting in high weighing precision (±0.5%) and   stability.
 2.3.2 Measuring Tank
 The measuring tank, which is equipped   with a liquid level transmitter, is made by 304 stainless steel. The measuring   accuracy is ±0.5%.
 2.3.3 Mixer
 The mixer is built by stainless steel for   high durability. It is equipped with a brush device to clean off the slurry   adhered to the hopper. The mixer uses a high speed agitator to ensure quick and   uniform mixing of the slurry.
 2.3.4 Forming Machine
 The forming machine   adopts the world advanced hydraulic jacking technique. The die cavity uses hard   chrome plated stainless steel, resulting in high surface hardness(≥HRC65) and   gloss finish (0.1μm). The clapboard and side mould are built by CNC machining   center for high dimensional accuracy (0.04mm), therefore, the dimensional   accuracy of gypsum block is well ensured. The sealing strips are made by high   polymer material, thus effectively avoiding leakage of slurry.
 2.3.5 Space   Clamp
 The space clamp adopts two-dimensional design. The crown block travel   motor and clamp elevating motor use frequency conversion control, with   positioning accuracy <1mm. Besides, imported ultra-thin cylinder is used to   ensure the gypsum blocks are uniformly stressed during clamping.
 2.3.6   Central Hydraulic Station
 The gypsum block forming machine uses design mode   of hydraulic station, which can greatly reduce power loss and improve operating   efficiency of the equipment. All hydraulic components are renowned brand   products, so their reliability and service life are highly guaranteed.
 2.3.7   Electrical Control Cabinet
 In order to ensure the smooth running of the   system and reduced downtime, we use famous brand electrical components,   including Mitsubishi or Siemens PLC and inverter, Schneider low-voltage   electrical parts, Chint cabinet body, etc.
