How to Select the Most Suitable Large Jaw Crusher Equipment

For aggregate plants, jaw crushers can accommodate varying operating conditions and output requirements, making them well-suited for production line configurations. Regarding the selection of jaw crushers, OCP Heavy Industry offers the following recommendations for reference:

A. Material Properties

The hardness, clay content, and moisture content of the material are crucial data points. Selection is primarily determined by the size of the raw material. Additionally, the primary crusher should be chosen based on the aggregate size of the stone. For instance, smaller feed sizes can proceed directly to secondary crushing equipment.

For exceptionally hard materials like granite, basalt, or river pebbles, jaw crushers or cone crushers are recommended. Softer rocks such as limestone may undergo secondary crushing with impact crushers. This approach minimises wear on vulnerable components like toggle plates, thereby reducing production costs and enhancing efficiency.

B. Product Quality Requirements

Customer specifications for finished aggregate size and particle shape also dictate the appropriate crushing equipment selection. Where finished aggregates require varying sizes, screening equipment must be integrated for classification.

C. Purpose of the Finished Product

Requirements for aggregate vary across road construction, hydraulic engineering, infrastructure development, and bridge projects. Crushing equipment must be rationally arranged according to the user's intended aggregate specifications. Projects with stringent aggregate requirements face increased collapse risks if cracked or sharp-edged stones are incorporated during construction.
