Gypsum Processing Equipment
In gypsum processing plant, crushing, grinding gypsum into powder will be the important step, within this gypsum mining procedure, the machinery we common use is crushing quipment, hoist, electromagnetic feeder, grinding machine, fluidized bed furnace( gypsum calcining equipment ), bunker, belt conveyor and mud collector.
equipment for mining gypsum
Since olden days, gypsum has been used to create monuments. Moreover, within the centuries, its fire-resistant qualities are making it a vital building material. Gypsum is probably the more widespread minerals in sedimentary environments. This is a major rock forming mineral that creates massive beds, usually from precipitation from highly saline waters. As it forms easily from saline water, gypsum may have many inclusions of other minerals and also trapped bubbles of air and water. Natural gypsum is a mineral extracted from quarries by means of small white crystals, clumped together in blocks. It comes down from a sedimentary rock made from calcium sulfate dehydrate. Crystals of gypsum can be extremely colorless and transparent, building a strong contrast towards the most common usage in drywall. Gypsum is really a natural insulator, feeling warm to touch compared to a more ordinary rock or quartz crystal.
Gypsum Mill Plant in Grinding Process
The grinding mill used in gypsum processing plant usually is the raymond mill. Raymond mill normally has three models: 3R2714, 4R3216, 5R4119. The finished size could be upto 0.044mm, and may be adjusted from 100 mesh to 325 mesh. Other grinding mill can be used including ultrafine mill, trapezium mill.
The gypsum powder production line
The gypsum powder production line includes four process flow: crushing, grinding, calcine, storing and feeding.
By using loader to feed the gypsum rock to the raw material storage bin. And then it’ll be utilized in the crusher to become crushed. Gypsum rocks is crushed into particles less than 30 mm by gypsum crusher, Then gypsum particles is feeded into raymond mill for grinding into partical size by electromagnetic feeder. The gypsum powder that fulfill the dependence on size is transported into fluidized bed furnace for burning. When heating and calcining the dehydrate gypsum and chemical gypsum (ardealite, desulphurization plaster, fluorgypsum), the dehydrate gypsum was decomposed, we obtain the semi-hydrated gypsum, i. E., plaster of Paris.
Dry process flow: plaster stone go through primary crushing process using jaw crusher, the scale is less than 8 cm, a tight schedule through secondary crushing process, within this process, cone crusher is used as fine crusher, then a sie is lower than 2 cm. After calcination, the calcined gypsum is grinded into the powder with 200-325 mesh by gypsum mill.
