A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand, or rock dust, which is consists of thousands of parts. These thousands of parts are called crusher parts. According to its frequency replacement and function, the crusher parts are divided into crusher spare parts and crusher wear parts.
Different types of crusher, there are different crusher parts types.
A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.
Based on its frequency replacement and function, the jaw crusher parts are divided into jaw crusher spare parts and jaw crusher wear parts.
Jaw crusher wear parts include:
Jaw crusher main spare parts include:
A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction are determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the material gets smaller as it moves down through the wear liner as the opening in the cavity gets tighter. The crushed material is discharged at the bottom of the machine after they pass through the cavity.
Based on its frequency replacement and function, the cone crusher parts are divided into cone crusher spare parts and cone crusher wear parts. Details check the right standard cone crusher structure picture.

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. The gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.
Based on its frequency replacement and function, the gyratory crusher parts are divided into gyratory crusher spare parts and gyratory crusher wear parts. Details check the right standard gyratory crusher structure picture.

Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.
VSI crushers use a different approach involving a high-speed rotor with wear resistant tips and a crushing chamber designed to ‘throw’ the rock against. The VSI crushers utilize velocity rather than surface force as the predominant force to break the rock. In its natural state, rock has a jagged and uneven surface.
Common VSI wear parts include:
Common VSI spare parts include:
The HSI crushers break rock by impacting the rock with hammers that are fixed upon the outer edge of a spinning rotor. HSI machines are sold in Stationary, trailer mounted and crawler mounted configurations. HSI’s are used in recycling, hard rock, and soft materials. In earlier years the practical use of HSI crushers is limited to soft materials and non-abrasive materials, such as limestone, phosphate, gypsum, weathered shales, however, improvements in metallurgy have changed the application of these machines.
Common VSI wear parts include:
Common VSI spare parts include:
A gyratory crusher is made of six main assembly parts. Base, mainframe and concave liners, Drive assembly, mantle, spider arm assembly, and oil system.
If you need original OEM crusher parts, you can check with your crusher brand manufacturer or local part department agency. If you need aftermarket replacement crusher parts, the price can be the following.
For some spare parts, such as hose, bolt, nuts, pins, seal, adapter, motor, and other spare parts, the price is based on per pcs or set. Those aftermarket replacement spare parts price around 40%-60% of the original parts.
For casting wear parts, such as jaw plate, cone liner, blow bars, mantles, and other casting wear parts, the price is based on the casting material. For example, a set of jaw plate, weight:1000kg, material: Mn18Cr2.
The price USD2200 = Pattern fee(USD600, USD0.6 per kg for wood pattern) +Casting fee (USD1600, USD1.6 per kg for Mn18Cr2)
All crusher plant have their part manuals. When you purchase the crusher, you can get the operation manual and part manual. Check in the manual book to find which part number crusher parts your inquiry.
If you need aftermarket crusher parts, you also can ask a professional engineer to measure the drawings or send a sample product to our suppliers.
If end-users need the original OEM parts, just check with the original parts departments or local agency. If end-users need the aftermarket replacement parts and want to find the right aftermarket parts suppliers, the following things must be prepared:
The part numbers can find in the operation manual book. Some part numbers also cast in the part unwork surface.
The drawings can purchase from drawings businessmen or ask a professional engineer to measure CAD drawings.
For most of casting wear parts, check the quality by sizes report, material report, Mechanical behavior report, and flaw detection report.
