Complete Quarry Plant Setup


Crushing plants must be designed for ease of access and maintainability if they are to meet their production goals. Keeping maintenance requirements to a minimum helps achieve higher overall operating availability. A modern, well designed and operated three-step, traditional plant can, however – much depending on the rock type – deliver quite satisfactory, clean and cubical products in the sizes above approximately 8 mm. The most critical size range for such a plant is between approximately 2 and 8 mm, where it is extremely difficult to obtain a good, cubical shape. As for the finest fractions, their particle shape will for most rock types be a function first of all of the mineral texture – but the crushing process does not assist to cubicity.

There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.

hard rock quarry plant design

The design of hard rock quarry plants is often a more complicated task than that for sand and gravel operations. All of the basic principles remain generally the same however. Added difficulties arise in consideration of more complex geotechnical domains, typically higher capital and operating costs, extra environmental impacts and more complicated restoration requirements. The granite quarry plant designer should attempt to reconcile each problem area before progressing designs too far. There should be regular reviews and discussions with other experts, particularly related to geotechnical issues and possible operational issues (including types of plant to be used). Restoration measures will be an area that needs much attention. Agreements will need to be reached with licensing authorities regarding the general principles to be adopted, but mechanisms need to be included to allow for changes as circumstances arise on site.
