Product Description
Gypsum into gypsum and anhydrite. Building gypsum from two natural gypsum or chemical gypsum after calcination temperature heating certain, so that the two water gypsum dehydration decomposes, grinding to obtain semi hydrated gypsum as the main component of the product type beta hemihydrate gypsum, which is building gypsum (or habits called plaster of Paris). Building gypsum production equipment mainly comprises a rotary kiln, grinding machine etc..
Beta hemihydrate gypsum is the main form of building gypsum, its production process can be summarized as gypsum calcining, crushing, grinding the three processes.
He first gypsum ore using jaw crusher, counterattack crusher to about 30 mm, fine grinding of delivery to the mill. Into the input rotary kiln calcining gypsum powder grinding powder selecting machine will reach the products required fineness, not in conformity with the will to return mill for fine grinding to meet the product particle size after calcination. http://crusher.quartzsandmaker.com/
It is a main equipment of beta hemihydrate gypsum is building gypsum production are: jaw crusher, impact crusher and grinder, milling machine selection according to the requirements of different fineness and the choice of. 0 - 3MM thick powder field, select the European version of the coarse grinding; 80-400 mesh fine powder selected MTW Euro mill and vertical mill; ultrafine powder of 400-3250 mesh selection HGM tricyclic ultrafine mill and ultrafine LUM vertical mill.
Building gypsum production in order to stabilize the production of calcined gypsum rock in different grade, the homogenizing field pre homogenization. Then the gypsum by feeder evenly feeding jaw crusher, broken into 10-25mm particle size, and then by the crusher for crushing, a bucket type lifting machine, hopper, feeder into the rotary kiln dehydration after grinding.
Through the building gypsum powder products of ore dressing - crushing grinding, calcining process production line of good quality, due to the low temperature heat source, gypsum is not easy to be burnt, as long as the control of discharge temperature appropriate, finished product does not contain two water gypsum, anhydrite is only 5% or less, the rest are semi hydrated gypsum. This composition is very ideal, stable physical property, such as the production of construction industry has been in the major area successfully put into operation on gypsum board.
