The fundamental goal for the design of a crushing plant is an

installation that meets the required production requirements, operates

at competitive cost, complies with today’s tough environmental

regulations, and can be built at a reasonable price despite the rising

costs of equipment, energy and construction labor. The following

industry trends must be taken into account:

Equipment suppliers are offering ever-larger primary crushers, with

1,800 mm (72 in) gyratories expected soon, as well as secondary and

tertiary machines of up to 3,000 mm (120 in).

Rising energy costs are causing owners to increase the integration of

mine and mill design, so that they can identify ways of reducing

overall electrical power consumption.

Electronic control of crusher discharge opening and feed rate. With

adjustment of a crusher’s discharge opening, as the production

continues through an on-line coarse size analysis of the crushed

product (digital image analyses). Dance, A. 2001)

More attention is being paid to the impact on crushing circuit design

caused by variations in ore characteristics, size distribution,

moisture content, ore grade and climatic conditions.

Operators have always dreamed of reducing the need for crushing

machine. In other words, crushing plants, from primary to quaternary

circuits, are here to stay.

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

36201185708ber 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.
