Crushing machines—also referred to as crushers—are designed to break large, dense materials (e.g., stone and ore) into more manageable forms. They are commonly used in quarries to reduce larger materials into smaller, size-specific pieces and aggregate plants to produce smaller rocks and powders for use in asphalt, concrete, and gravel.

With sales and support in 27 countries, Copps Industries is a well-known name in aggregate plants, quarries, and mines throughout the world. Our 100% solids, VOC-free crusher backing products have been in use for over 30 years. This line of products ranges from our workhorse-standard backing to our high-performance backing to our industry-leading non-corrosive products.
Crushers use a variety of different motions, forces, and overall styles of crushing in order to best produce the broken-down product in the intended size as efficiently as possible. Crushing applications typically fall into four categories:
Crushers operate on a very basic mechanical principle—rock is compressed between two harder surfaces until it breaks into smaller pieces. As the crushed materials are typically quite hard on their own, the crushing process causes significant wear and tear on crushing machines. For this reason, many crushers are integrated with crusher backing compounds.
At Copps Industries, we manufacture a complete line of epoxy-based crusher backing compounds. These durable and shock-absorbing materials play a pivotal role in the protection and reinforcement of heavy-duty mining and quarry equipment.
Crusher backing compounds protect crushing machines from unnecessary damage and long-term wear by filling the open cavities behind wear parts and supporting (i.e., backing up) wear surfaces. In doing so, they minimize the effect of friction, vibration, and impact on the machinery during crushing operations.
The Copps Industries team continually improves on the formulation of products using the most current raw materials to accommodate the needs of even the most demanding applications. Through these unique innovations and our tried-and-true standard product line offerings, we offer a broad selection of crusher backing compounds to suit the requirements of any crushing application or operation. For example:
Our products find use in a variety of crushing equipment, including the following:
Cone crushers are a form of compression crushing machines, which reduce the size of materials by squeezing or crushing them until they break. They consist of an eccentrically rotating steel component (i.e., the mantle) and a stationary steel component (i.e., the bowl). As the material moves from the top of the cone down, it is crushed into smaller and smaller pieces until it is small enough to exit through a hole at the bottom. The final size of the material is determined by the bottom gap between the two crushing components (i.e., the close side setting).
Gyratory crushers are similar in shape and operation to cone crushers. However, their moving crushing components gyrate (i.e., oscillate along a circular path) rather than rotate. The crushing head can be height-adjusted, and the hole at the bottom of the crushing chamber determines the final size of the crushed material.
As suggested by the name, stone crushers are designed to break stone into smaller pieces. They can be used to process a variety of stone materials, ranging from soft minerals to hard stones, for various industrial applications (e.g., chemistry, demolition, metallurgy, mining, etc.). They are available in a wide range of designs and configurations to suit different crushing requirements, including cone crushers, hammer crushers, impact crushers, and jaw crushers.
Grinding mills are used to reduce raw materials to a powder form. While their design and configuration can vary, they generally consist of a rotating grinding chamber with balls, rods, pebbles, or other grinding media to break up the material into the desired size.
Backing plates are used in crushers and grinders to provide protection from loose material impact, vibration, and noise. By mitigating the effect of impact and vibration on equipment, they reduce overall maintenance costs and extend overall service life. Additionally, by lowering noise levels, they protect the hearing of personnel working in close proximity to crushing equipment.
Lock bushings are engineered to allow for quick and easy installation of other components to shaft assemblies. They securely fasten components without the risk of loosening even when exposed to high impact and vibrations, which makes them ideal for use in mining and quarry equipment.
Crusher backing compounds offer a range of benefits for mining and aggregate operations, such as:
In addition to selecting the right crusher backing compound for a crusher and applying it properly, it is important to periodically inspect and service crushing equipment to ensure it remains in optimal operating condition. Otherwise, there is a risk of the crusher backing compound degrading without notice and the crusher being exposed to harsh conditions.
There are three maintenance methods available:
Investing in a maintenance plan that incorporates all of these maintenance methods, especially preventative and predictive maintenance, can help ensure crushing equipment remains in operating condition for the duration of its expected service life.
