Comminution Circuits for Gold Ore Processing
Currently, every AG/SAG flowsheet evaluation is likely to consider the inclusion of a pebble crusher circuit. Flowsheets that do not elect to include pebble crushing at construction and commissioning may include provisions for future retrofitting a pebble-crushing circuit. Important aspects of pebble crusher circuit design include: •

Roll Crusher
6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.

Crusher Circuit Capacity and Feed Quality
The fourth operating variable is the capacity of the crushing circuit. We have talked about the size of the ore, the hardness, and the condition of the equipment, the RPM, and the speed in which the crusher will crush the ore. The sum of these things add up to the crushing capacity of the crusher itself. If conditions are exactly right and not ...

iron ore crusher plant design step by step
Step 3:Design the crushing circuit. Once the crushing equipment has been selected, the crushing circuit can be designed. The crushing circuit is the layout of the crushing equipment and the flow of material through the plant. The crushing circuit should be designed to achieve the desired output and particle size of the crushed iron ore.

Gyratory and Cone Crusher
The feed size to a primary crusher from the mines could be 1–1.5 m; thus, the maximum product size possible is 10–15 cm which is normally too large for down stream processing for mineral liberation. Hence, secondary and possibly tertiary crusher stages form part of the crushing circuit design.

Scientific Methods to Design Crushing and Screening Plants
An important point often overlooked by plant design and application people is that the crusher must have an adequate amount of evenly distributed feed. Figure 8 shows the effect of poor and good feed distribution. If the feed is correct, the crusher will have maximum produc- tivity (highest average crushing force) for minimum mechanical stress.
