Gypsum mining industry brings high profits to economy development. Obviously, the gypsum mining equipment plays an important role in the mining process.
Gypsum beneficiation processing Plant
Though photoelectric separation, gravity medium beneficiation, flotation and electricity selection can be applied in gypsum beneficiation. However, these methods are not widely used in industry production. Most mines just have the hand selection to the mined gypsum ore to separate the sand. The complicated mines separate the sericolite, common gypsum and little hard gypsum with hand.
Gypsum Technological process
Gypsum production technological process is: ore storing→crushing→homogenizing→calcining and dewatering→aging→grinding and mixture→package.
Gypsum dry calcining technology is: the gypsum is selected and stored from quarry site to ensure the high quality feeding material. Jaw crusher crushes the feeding materials to less than 8cm, with hammer crusher to have secondary crushing to crush materials to less than 2cm. Through the bucket elevator, gypsum enters into the calcining kiln.
Wet calcining technological process generally includes: gypsum raw material bin→bolting mill→autoclave→crushing and grinding→homogenizing and storing→package
Common technological equipment: The most widely used crushing equipment includes: jaw crusher, cone crusher, impact crusher, roll crusher, hammer crusher etc.
Dry calcining has two kinds of equipment: direct calcining and indirect calcining. The direct calcining equipment: rotary kiln, crushing, grinding and calcining integration equipment.
