What Are Crusher Wear Parts?

A crusher wear part is a metal part that is designed to withstand excessive wear and tear from crushing and grinding, such as those found in a jaw crusher or cone crusher. Many parts are made of steel because of their strength and durability. However, different types of metals can be used depending on the application.

The Top 7 Wear Parts for Crushers

There are many Crusher Wear Parts on the market for this equipment, but today we’ll focus on some of them.

1. Wear Rings

Having holes in it increases its strength after being abraded occasionally by the crushing wheel teeth to improve how long they will last in service and reduce downtime when needed, then washed or rinsed off with water before re-use. You can find different steel materials for these rings, but aluminium works best for this application.

2. Wear Pads

Their special composition provides a barrier to protect the wearing surfaces of running parts and cutting tooling against abrasive wear during the normal operation of equipment. These pads are usually made with polyurethane or polyester impregnated material that prevents damage caused by abrasion between it and the crushing surface when in contact.

3. Wear Rolls

Usually made from non-corrosive metals, they are applied to the area where heavy crushing or milling actions take place. It can be a simple tapered roller over large surfaces of more complicated rings and spirals which can work together as a complete system for total protection of sensitive areas against wear damage due to repeated grinding forces during keeping equipment in continuous operation without failure through extended periods.

4. Spindles

These machining components provide rotational and longitudinal thrust against the wear surfaces of tools, reducing abrasion.

5. Guide Bars

You’ll need them if you use a turning center to cut work piece parts with round cross-sections such as dies & tooling chucks, for instance. Due to the flatness of topcoat finishes on high-speed center spindles, they may require hard grooves to achieve the best static and dynamic conditions for optimal performance of the most sophisticated machining centers.

6. Feed & Spur Gears

Having feed, speed control with mechanical advantage you can decrease cutting force (and improve accuracy) by using such gearing such as helical gears or compound planetary gearboxes – Also used to transmit rotational forces from motor shafts or connecting rods inside high power engines to reduce stress on engine components and ensure smooth drive behavior under any conditions.

7. Planetary Gearbox

These are very useful in the design of many high-speed rotary axis systems where the considerable thrust is required or desired to keep larger cutting tools resting on top of the cutter with their surfaces engaged against feed rolls & solid carbide wheels for all types of machining operations used against complex steel castings, complex boring bars and cooling bush chips. The arrangement allows operating speeds exceeding 3500 rpm (and even higher) whilst maintaining a high feed pressure and controlling drilling forces to eliminate chatter.


You have just been introduced to some of the most commonly used wear parts for crushers that can prolong the life of your equipment and reduce its downtime. These are the most commonly used parts in the industry. I hope this gives you some ideas for starting your own project.
