50-500tph China wholesale double toggle jaw crusher
introduction of double toggle jaw crusher:
double toggle jaw 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.
double toggle jaw 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.
double toggle jaw crusher working principle:
double toggle jaw crusher mainly consists of frame, eccentric shaft, jaw plate, connecting bar, adjustment part and spring.
The movable jaw goes upward and downward through eccentric shaft when belt and belt wheel are driven by the motor. The angle between movable jaw and bracket turns big when the movable jaw goes upward, which pushes the movable jaw plate to come closely to fixed jaw plate. At the same time, materials are crushed with the movement of the movable jaw.
When the movable jaw goes downward, the angle between movable jaw and bracket turns small. Under the force of spring and connecting bars, the movable jaw plate leaves fixed jaw plate, and the crushed materials with qualified size are discharged from the crushing cavity. With the continuous rotation of the motor, the movable jaw crushes and discharges materials, which, in turn, realizes the goal of mass production.
Features of double toggle jaw crusher :
1. The double toggle jaw 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..
Application of double toggle jaw crusher :
The series of double toggle jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush. They can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.
