Gypsum Mining,Gypsum mining equipment
There is no overburden. The gypsum occurs from the surface to a depth of about 1.5 metres. Mining is by excavator, with dump trucks delivering to the stockpile site. At Elephant Lake selective mining has enabled separation of the top 0.3 metres, consisting of ultrafine gypsite, from the underlying slightly coarser but purer gypsarenite.
The freshly mined and stockpiled gypsum contains small amounts of sodium chloride. Draining of wet freshly mined gypsum in stockpiles, with additional leaching by rainwater, lowers the salt content. All gypsum sold has well below the permissible maximum of 2% salt for agricultural use.
Power screeningAfter leaching and drying the stockpiled gypsum is power screened to -10mm.
Coal mill machine used for thermal power plant
In coal fired power plant, coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.
The hot air in the coal mill will lift the coal particles out of the Raymond mill or vertical mill and into the boiler, if the coal particles are too heavy they will drop to the bottom of the coal mill too and will be grind, pulverize again.
The coal flow into the boiler is an important factor for a coal fired power plant. But in fact, it is not easy to measure the coal flow from the coal mill to the furnace. The coal flow out of the coal mill is often estimated based on the incoming coal flow.
Sand Making Plant
Sand washing Plant or making plant consists of vibrating feeder, jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine, belt conveyor and centrally electric controlling system, etc. The designed capacity is from 50t/h to 500t/h.If you need the washing plant,you will consists vsi crusher and the sand washer,you can also only use the sand washing machine or the sand making machine.
The Veritcal Shaft Impact crusher is a product based on many professionals' wisdom and right decision in mining industry. The Vertical Shaft Impact Crusher is internationally advanced equipment with low energy consumption. It plays a unique role in crushing equipment. VSI crusher is widely used in various materials crushing, cement, fireproof materials, bauxite, diamond, glass, construction sand, stone material and other clinker and slag in metallurgical industry. It bears the merits of simple structure, self-impact crush, low operation cost, stable operation, little noise, high efficiency, energy saving, high reduction ratio and little erasion in spare parts. In addition, the quick-wear parts of this machine are made of choiced wear-resistance materials, which ensured its long using time.
