Professional manufacturer of jaw crusher, grinding mill, mobile crusher... welcome to LiMing Heavy Industry.
To achieve the ideal using effect, the key point is reasonable type choosing. Coal Fractional Crusher is not just a single machine according to the whole coal separating system.
There are different washing craft according to different coal separating system such as jigging, pressure heavy-medium cyclone, un-pressure heavy-medium cyclone, shallow trough, etc with different requirement for raw coal granularity.
Aiming at different coal handling capacity, hardness of coal, gangue content and hardness directly decide the coal crusher's installing power, while the constitute of granularity is the key factor for deciding the fractional crusher equipment.
Considering the technological features and price, the granularity, handling capacity, over-crushing, lifespan of crushing tooth-gear. Objectively selecting the product with high performance in lower price is very important.
The impurity in coal means ironware, large wood, wire-line, etc. Because the classificational crushing equipment has more than 160MPa, while coal gangue has the hardness under 120MPa, which can not be too overthinking. Different raw coal has big difference on impurity. Often the large mine adopt the vertical digging method with main impurity of ironware, which should equip iron de-duster with high effect before using the fractional coal crushing equipment. If the coal is transported from another place especially the small coal kiln, the main impurity is wood and wire-line, which is suggested to use screening before crushing. Besides, if the raw coal is of low quality with more coal gangue, the smaller granularity before washing the coal, but the simplified flow of fractional is not advised.
The fractional coal crusher is considered as a whole new concept crushing equipment with easy flow craft, simple structure and granularity ensuring tightly, which is the first choice for coal and coke crushing equipment and is widely used in coal industry with better effect.
Jaw crushers are typically used as primary crushers, or the first step in the process of reducing ro
