cost estimate of a crushing plant

Capital Cost Direct Costs. The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. It’s necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects:

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.

Installing a primary crushing plant on solid rock reduces the cost of concrete and structural steel. The life of the mine is a key element in the design of any crushing plant. Short-term mine lives (three to eight years) require a very careful approach to design, layout and construction.

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 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.

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.
