30 x 42 jaw crusher introduction:

30 x 42 jaw crusher is one of the most popular stone crushing machines used in mining industry and it is ideally suitable for both primary and secondary crushing. PEW series single toggle jaw crusher has the features of great crushing ratio and uniform sizes. It can be used to crush materials with compressive resistance less than 320 MPA. It is widely used in various industries, such as mining, smelting, road and railway construction, chemical industry, etc. 30 x 42 jaw crusher is used for primary crushing and secondary crushing.The maximum compression strength of materials to be crushed is 320MPA. Our design and production are of high position both at home and abroad.

working principle of 30 x 42 jaw crusher 

This series 30 x 42 jaw crusher adopts electric motor as the power, and the eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw to follow the pre concerted path and crush the in-fed materials, and then the materials will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. Finally the finished materials are discharged from the lower part of machine.

Please carefully examine the fasteners, especially the lubrication components and bolts before starting the machine. Enough oil is needed on each lubrication component. Fasten the loose bolts, clean the crushing cavity, and then start the machine. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.

Features of 30 x 42 jaw crusher 

1. 30 x 42 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.
7.The 30 x 42 jaw crusher employ the American technology.

Application of  30 x 42 jaw crusher 

The 30 x 42 jaw crusher is mainly used in metallurgy, mining, chemical, cement, construction, refractories and ceramics in the industrial sector for a variety of pieces and crushing of hard ores and rocks with.
2, The 30 x 42 jaw crusher best suited to the compressive strength is not higher than 250MPa (MPa) of various hard and soft ore was broken material shall be not greater than the largest block of technical parameters the law.
