Contract Crushing

Providing Access to Rock, Crushed on Your Site

Traditionally most rock crushing has been done with fixed crushing and screening plants based at large quarries.

While this approach has its benefits there are many instances where this approach is uneconomic. Where volumes are smaller, where the job is a “one-off” for a certain project or where physical limitations such as access and availability of electricity are insurmountable hurdles, mobile crushing just might be your answer.  

You may be wondering: is contract servicing the right choice for my job? Will it be efficient? To answer your question, contract crushing is often the best choice for cost efficiency, capability, and long-term site potential. 


Your capability to execute the job is a very important factor to consider. Key things to think about include:

  • What type of material is being crushed?
  • How much material will you be processing?
  • How much product will need to be output?

Contract crushing provides access to superior capability. Crushing large amounts of tough material is no problem. Producing product is also a lot easier with the right capability. Specialist equipment is used to get the right cut, size, and volume. Without this equipment, your output can be compromised. If you need to produce a specific product that requires specialist equipment, contract crushing can help. 

Cost Efficiency

Significant time, labour, and cost go into a crushing operation. Several considerations are required to enable the best value for your job. Resource costs can be significant when it comes to a crushing job. The major question we hear is, “should I invest in my own equipment?”

Our answer to that is, executing a crushing site requires sizeable capital expenditure. But with contract crushing, that expenditure can be made more cost-effective, providing you with more value for money. This is because we have the right tools and equipment to get the job done. You eliminate the guesswork and extra labour involved with planning and purchasing new tools for the job.

We have already made the capital investment, so paying for our service would tend to be a more cost-efficient choice. Simply put, you forgo having to purchase expensive crushing equipment. If you have not yet purchased crushing equipment, or if you do not have the resources available to dedicate crushing equipment to a new site, we can help you.
