Common Crushers In Mining Industries

Currently, there are several common crushers applied in mining industries such as jaw crushers, cone crushers, vertical impact crushers, impact crushers and so on.Jaw crushers make the use of two jaw plates to crush materials which is usually applied in coarsen crushing and hard materials.It consists of fixed jaw plate and movable jaw plate.When the two plates move closer the materials will be crushed, on the opposite materials will be discharge when the size of materials is less than the discharging gate.Working principle of this kind crushers is interval with simple structure, reliable operation and hard material crushing.Cone crushers own the same working principle with gyratory crusher except its application is second crushing or fine crushing for these kinds of crushing having higher standard about the even discharging than coursing crushing.Hence there sets a parallel zone in the crushing cavity bottom.Meanwhile we need to speed the gyratory cone to make sure that the materials crushed more than one time.Vertical impact crusher is mainly applied in crushing soft or middle hardness and most hard materials such as kinds of ores, cement, refractory material, aluminum clinker, carborundum, glass, machine-made sand, stones and mineral waste residue and so on, especially ultra hard and wear-resisting materials such as silicon carbide, emery, sintering bauxite and so on.In this way this kind crushers is more efficiency than others.Impact crushers is to make use of high speed impacting of the hammer and the spring back function of plates to crush.Today, we bring the application of gold mining in the gold mine mill mine.Take chassoul united states, for example.The gold mine is located chassoul 70 km north-west of costa rica in san jose.Veritas gold property,a subsidiary of ascot mining mine covers an area of 400 hectares and consists of nine identified veins.Its development was launched in 1991.Veritas gold has started production at the mining in september 2009.In the gold mines, small type breakers.The gold mineralization at the mine chassoul shows four styles weak hydrothermal alteration, including or propylitic, medium clay, strong argillic alteration and silica.The boulder was set to jump into the air.And then it would be in the jaw crusher or press indrectly in impact crusher or hammer crusher which reduces it less than half the size.Oversize ore back to the crusher on a vibrating screen, while the fines, the bin is delivered ore fines.All over the world ,mill is also reduced the fines to match the size and consistency of flour.The material of the type of flour is then solution sent to the leach tank, filled with a dilute solution of cyanide.It is calculated on mechanical methods and / or air.Fresh material is added continuously added.The initial plant capacity 20t / d has an average grade of 15g / t.The capacity is expected to 50t / d and gradually to 150 t / d that the circuit is to increase balanced jaw crushers.
