Understanding Crusher Backing Materials

Crusher backing materials are compounds designed to provide support and enhance the performance of wear parts in crushers. These materials are used to fill the gaps between liners and crusher body, reducing vibrations and minimizing the impact of friction and abrasion. The primary purpose of using crusher backing materials is to ensure proper alignment and support of wear parts, which in turn leads to improved crusher efficiency, reduced downtime, and increased operational safety.

Importance of Crusher Backing Materials

  1. Enhanced Performance: Crusher backing materials help maintain the structural integrity of crushers, reducing the risk of premature wear and tear on crucial components. This results in improved overall crushing performance and consistent product quality.
  2. Reduced Downtime: By providing a secure and reliable bond between wear parts and the crusher body, backing materials help prevent unplanned shutdowns due to component failures. This translates into reduced maintenance costs and increased operational uptime.
  3. Safety: Crusher backing materials enhance workplace safety by preventing parts from dislodging during operation. This prevents hazards such as flying debris and potential accidents that could result from equipment malfunction.

Types of Crusher Backing Materials

  1. Epoxy-based Backing Materials: Epoxy compounds are the most commonly used crusher backing materials. They offer excellent adhesion, high compressive strength, and resistance to temperature fluctuations. Epoxy-based materials are versatile and suitable for various crusher types.
  2. Polyurethane-based Backing Materials: Polyurethane compounds are known for their flexibility and impact resistance. They are particularly effective in applications where dynamic forces and vibrations are prevalent.
  3. Acrylic-based Backing Materials: Acrylic-based materials provide good impact resistance and are relatively easy to work with. They are often used in less demanding crusher applications.

Applications of Crusher Backing Materials

  1. Cone Crushers: Cone crushers require precise alignment of wear parts to ensure proper functioning. Crusher backing materials are extensively used in cone crushers to maintain proper gap settings and prevent wear-related issues.
  2. Gyratory Crushers: Gyratory crushers also benefit from the use of backing materials, as they provide stability to the concave segments and reduce the risk of displacements during operation.
  3. Jaw Crushers: While less common in jaw crushers, backing materials can still play a role in reducing wear and enhancing performance, especially in heavy-duty applications.


The crusher backing materials industry plays an integral role in ensuring the reliability, performance, and safety of crushers across various industries, including mining, construction, and aggregates. While often unseen, these materials contribute significantly to the efficient operation of crushers by providing the necessary support and stability to wear parts. As technology continues to advance, we can expect further innovations in the formulation of crusher backing materials, leading to even better performance, extended equipment lifetimes, and safer working environments. So, the next time you witness a crusher in action, remember that behind its robust performance lies the unsung hero of the crusher backing material.
