7.5.2 Circuit Operation. Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12 ).
Fixed Plants are of more heavy duty construction and purpose built for the specific application.

debottlenecking in a crushing plant is a challenging task because it requires information and experience of the plant. The bottleneck in an open circuit is often the last production unit, which ensures steady output from plant. In closed circuit, it may however be a bit more complex causing some problems. Fig. 2.
This is a step-up from other 200 hp (149 kW) closed circuit plants with the MVP280 cone and its adjust-on-the-go capability. Crusher settings can be changed fast and easily without shutting off feed to the plant. This closed circuit plant, teamed up with a jaw plant makes a very portable and productive two-stage crushing system.
A surge pile between crusher and milling circuit isolates the milling circuit from the generally lower availability achieved in crushing circuits. • Feed to the milling circuit needs to be steady and crusher discharge can often fluctuate somewhat, particularly with smaller crushing plants. • A stockpile can be used to blend ore from ...
