Gypsum Powder Machinery

The advantages of this method are high yield, high frying efficiency, quick solidification of the obtained Plaster, low strength, but complex equipment.

First, crush the Plaster into fine sand particles, then stir fry it, and then crush and screen it.

Use a general squirrel cage crusher to crush, select, and screen. The advantage of this method is that it has the advantages of the first two methods, but the process is relatively complex.

Pressure steaming method for frying paste

Gypsum Powder Machinery

This 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. This type of hemihydrate Plaster is in the A-crystal form, and the strength of the model flipped with this type of hemihydrate Plaster is very high, but the equipment for this frying method is more complex.

Regardless of the method, the fineness of Plaster powder generally requires a residue of no more than 0.5% on the 80-120 mesh sieve.

Five major systems of building Plaster powder production line

According to the process requirements, the construction Plaster production line is usually divided into five parts, namely the crushing system, grinding system, calcination system, storage and transportation system, and electrical control system.
