Crushers Barry A Wills James A Finch FRSC FCIM in Wills Mineral Processing Technology Eighth Edition 2016 Jaw crusher Construction Jaw crushers are heavy duty machines and hence must be robustly constructed The main frame is often made from cast iron or steel connected with tie bolts It is commonly made in sections so that it can be transported
While there are many different kinds of jaw crushers on the market two types are predominantly used the single toggle jaw crusher and the double toggle jaw crusher Single toggle jaw crushers a seemingly simple yet complex mechanism have a swing jaw which moves in an elliptical path from the bottom to the top of the crushing chamber On the
Throughput Needs High volume projects might benefit more from jaw crushers which can process large amounts of material quickly Impact crushers while efficient may have a lower capacity for large volumes but provide precision in the final product s size and shape 4 Operation Costs and Efficiency
Jaw crushers are used as the primary crushers in the first stage of the crushing process Jaw crushers are preferred for when breaking large rocks is the priority rather than achieving high capacity Jaw crushers can be used as first stage crushers in small and medium sized plants as well as for secondary crushing when necessary
Further it can be also inferred that industrial jaw crushers which generally have higher crushing capacities will result in even more inefficient energy consumption as compared to the lab scale jaw crushers These results are also in line with previous research performed on granite rocks with industrial jaw crushers Numbi et al 2014 The

18 • Single Toggle Jaw Crusher • In the single toggle jaw crushers the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher • The swing jaw suspended on the eccentric undergoes two types of motion swing motion towards the fixed jaw due to the action of toggle plate and vertical
The working principle of primary crushers varies depending on the type of crusher but generally they work by reducing the size of the material through compression or impact In jaw crushers the material is fed into the crushing chamber and is crushed between a fixed jaw and a movable jaw Gyratory crushers work by crushing materials between
