design of a plant stems crusher

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.

The biggest change, which is now being introduced into the design of crushing plants is the design of the mining process as one complete system, from mine quarry and pit to the final product. Digital image analysis is now allowing electronic monitoring of the size distribution of the material being handled at any point in the product stream.

Safety and the working environment remain the two areas of plant design, which require more attention. Noise abatement and the reduction of dust emissions remain the goals of most operators and crushing plant designers.

The type and size of the primary crusher is influenced by the following factors: 1. Methods employed in drilling and blasting, 2. Type and size of equipment to be used. 3.

Primary crushing will see the introduction of bigger, 1,800 mm (72 in) gyratory crushers, and low-speed, high-tonnage roll sizers will become more generally accepted. These larger crushers are required to handle the higher throughputs, and 400- to 500-tonne capacity trucks, expected on some future projects.

Some plants are designed with no surge bin under the crusher, with a wide, high-speed take-away conveyor to take the surge (flush rate) to a nearby stockpile or to a external surge bin. Install floodlights in the surge pocket to facilitate inspection and maintenance.
