The VSI plays a critical part in obtaining high specification road stone, or as a pre-milling crusher to increase mill throughput in mining applications.

By tonnage, crushing is by far the largest process operation in aggregate processing

compressive strength to the strong and brittle natural rock types that serve as aggregate, crushing forms a vital and cost-effective part of the aggregate production process. “It allows us to reduce the particles to a required size under applied stress through one or more crushing stages in conjunction with screening to achieve the required specification of the final product,” he says. Van Rensburg adds that key aspects of designing and implementing a crushing circuit include, firstly, understanding as much as possible about the source material – such as the size of the rock entering the process, the hardness of the material and its abrasiveness. “Most importantly, the design must focus on exactly what output the customer requires – both in terms of particle size and

To execute the crushing process cost-effectively, it’s always important to deploy the correct crusher for the ideal application

Jaw crushers are typically used in a primary crushing station – to take the run of mine and produce a feed to the secondary cone crushers
