black rock crusher introduction:
black rock crusher are typically used as primary crushers, or the first step in the process of reducing rock. They typically crush using compression. The rock is dropped between two rigid pieces of metal, one of which then move inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
black rock crusher movement is obtained by using a pivot point located at one end of the "swing jaw", and an eccentric motion located at the opposite end.
black rock crusher working principle:
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
black rock crusher composition-structure:
black rock crusher is made up of frame, eccentric shaft, grooved wheel, flywheel, moving jaw, side guard plate, toggle plate, toggle backseat, adjusting screw, returning spring, fixed jaw plate and moving jaw plate. Toggle plate is of safety function.
Application of black rock crusher
1.widely applied in mining, road&railway, concrete, chemical and building material industries.
2.Ores and rocks with various hardness
3.Concrete basis and steel structure basis
4.Stationary, half-mobile and mobile applications
Main Advantages of black rock crusher :
1. The black rock crusher has a deep crushing cavity and the frame employs the joggle joint welding and entirely annealing technology which make the crusher a simple, durable and robust structure and improve the capability and the crushing ratio.
2.Digital simulation of the operating trace and speed of the movable jaw ensure a high capacity and low consumption rate of the ware parts.
3.Utilization rate of the tooth plate has been increased by using segmented tooth plates which are replaceable.
4.Hydraulic adjustment of the discharge opening ensures a more convenient and safe operation.
5.The service life of the toggle plate and adjustment seat has been developed by the double-layer adjustment seat with arc-shape liner inside it which will disperse the partial pressure evenly.
6.The frame could be taken into upper part and lower part which can be fixed together again by dowel pins. This sort of structure makes users easy to assembly, disassembly, transport and install the crusher.
