The jaw dies must be replaced regularly due to wear. Figure 8.1 shows two basic types of jaw crushers single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw.
Each failure leaves its own special imprint on the bearing. Consequently, by examining a failed or damaged bearing, it is possible in the major - ity of cases to establish the root cause and define corrective actions to prevent a recur - rence. This publication is intended to provide a basic understanding of bearing failures and failure analy sis.
Jul 23, 2017 Jaw Crushers. Jaw crushers, shown in Figure 6, are the oldest type of crusher in use. They are economical when dealing with a coarse or blocky feed although capacities are low. The swing jaw, powered by an eccentric, moves downward and toward the stationary jaw to crush, then moves up and back to allow crushed material to exit.

Nov 01, 2011 Having stopped the machine in an emergency, the jaw will be left full of rock. A clutch drive machine would have to be manually cleared however, a hydraulic machine can reverse jaw rotation and start up, the jaws still full, without danger of damage. Clearing a blockage is one of the most dangerous procedures when operating a crushing plant.

Jan 01, 2018 The cost estimate of manganese steel is about 2000 per ton. For the crusher machine using a crusher jaw of 2-tons size, 4 tons of manganese steel are consumed in an installation for a pair of crusher jaws. Let the failed wrongly postcast treated crusher jaw investigated be represented by CJ-1 and the correctly postcast treated one by CJ-2.
Figure 8.1 shows two basic types of jaw crushers single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates.
