In mining and aggregate operations, performance is everything. And when it comes to maintaining high performance, crusher backing compounds play a critical role.
Crusher backing is essential for maximizing liner life, ensuring machinery uptime, and optimizing your operations. But even the most advanced product can’t perform if it’s applied incorrectly. Proper application means full surface contact, reduced vibration, and extended life of wear parts—and your crusher overall.
Here, we’re taking a closer look at how crusher backing compounds work, covering the most common application mistakes, and providing step-by-step tips for optimal results.
The Role of Crusher Backing Compounds
Crusher backing compounds are designed to fill the gap between the liners and the crusher frame. This creates a solid, uniform backing that supports crusher liners and prolongs life as they wear.
Here’s how proper backing supports performance:
- Fills voids between liners and frame for maximum contact
- Non-shrinking formulation prevents gaps and misalignments
- Reduces vibration, enabling smoother, more efficient crushing
- Extends liner life and overall time between maintenance cycles
- Reduces unplanned downtime and repair costs

Common Application Mistakes (and How to Avoid Them)
Even the hardest-working backing compound won’t deliver results if it’s misapplied. Here are some of the most common application errors and how to prevent them:
Mistake: Improper surface preparation
Avoid it: Always clean and dry all surfaces thoroughly before pouring.
Mistake: Inadequate mixing or incorrect ratios
Avoid it: Mix the full kit thoroughly. Don’t attempt to eyeball or split proportions.
Mistake: Not conditioning the material
Avoid it: Pre-condition the material to remain within the recommended temperature range before and during use.
Mistake: Skipping curing it: Allow for the full recommended cure time before restarting the crusher, even if the surface feels hard.
Step-by-Step: Applying Crusher Backing the Right Way
Proper application is important, but there’s no need to overthink it. Here’s a simple checklist for applying crusher backing:
- Surface Prep: Clean and dry all bonding surfaces thoroughly to ensure adhesion.
- Mixing: Follow the instructions precisely and mix the entire kit.
- Pouring: Pour at recommended temperatures and fill the entire cavity to avoid voids.
- Curing: Let the compound fully cure before putting the equipment back into operation.
Pro Tips for Optimal Results
- Choose the right product: Large cone crushers often require high-performance backing for maximum support and durability. Copps manufactures a complete line of crusher backing products, including the premier High Performance Backing XP-2000.
- Train your team: Proper training in compound handling and application goes a long way toward preventing mistakes (and avoiding downtime).
- Plan for temperature: Remember that cold conditions will slow curing, while high heat can accelerate it. Be sure to adjust your process accordingly.
