Block is building gypsum plaster (plaster or natural chemical byproduct of a calcined gypsum) as the main raw materials: water stirred shaking, pouring into forming massive light and dry wall materials. Its main features are: light weight, shape and tidy and smooth surface, fire, heat insulation, noise and so on.

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 released 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 solid in opalescent colour. The surface of the block is smooth and plane with straight edges. The grooves and tongues are made on the vertical and horizontal sides for easy construction.

This method is still widely used in the domestic ceramic industry.Pressure steaming method for frying pasteThis method first preheats the raw Plaster with a block size of 25-50mm after coarse crushing in hot air at 60 ℃, and then places it in a pressure cooker for 5-7 hours with saturated superheated steam at 1,3 atmospheric pressure (125 ℃). Then, hot dry gas at 200 ℃ is introduced until hot dry gas is discharged, resulting in a vapor pressure of hemihydrate Plaster.

Plaster powder is one of the five gel materials and plays an important role in the national economy. Plaster powder production line is the natural dihydrate Plaster ore (raw Plaster) or industrial by-product Plaster (desulfurized Plaster, phosphoPlaster, etc.) calcined at a certain temperature. It is crushed to dehydrate and decompose the dihydrate Plaster.

Working principle of Wall Plaster MachineAfter the bulk material is broken, it is sent to the silo by the lift, and then evenly sent to the main grinding chamber by the electromagnetic vibration feeder. Material entering the grinding chamber is scooped up and placed between the grinding roller and the ring to be ground. After grinding, the fan blows air into the grinding chamber, and the powder is blown into the analyzer for sorting.
