mobile crushing plant

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 ¨C much depending on the rock type ¨C 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 ¨C but the crushing process does not assist to cubicity.

crushing plant design factors

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. These can include the owner¡¯s engineering staff, safety personnel, operations and maintenance personnel, equipment manufacturers, and the engineering consultant. Ideally, the consultant combines his knowledge and experience with an understanding of all parties¡¯ needs, to provide a balanced, workable, safe and economic plant design.

what you should take into consideration

A project¡¯s geographical location, topography, geotechnical conditions, remoteness and climate can all affect crusher plant design. Construction costs are generally much greater at high altitudes, in cold climates and at remote sites. To improve the economics of such locations, modular and pre-assembled structures and plant facilities are used prior to transportation to site. Local labor costs often dictate what material can be best used economically in a particular region; for example, cement structures are much cheaper to erect in Mexico than in Alaska.

Remote projects can suffer from difficulties in obtaining spare parts on short notice. Crushing plant design should accordingly provide for laydown and workspace for onsite equipment refurbishment and repair. Where possible, equipment manufacturers should be encouraged to stock and provide spare parts close to the mining operation. Good geotechnical information is essential to crushing plant siting and design. Installing a primary crushing plant on solid rock reduces the cost of concrete and structural steel.
