DESIGN CONSIDERATIONS FOR SUPPORTING STRUC TURES Location Crushers are usually located at a height of say - 15m above ground to facilitate easy feeding of coal from the overhead conveyors. The supporting structure is generally of an elevated steel or reinforced concrete framed construction.
In several actual cases the supporting structure cracked after experiencing high vibration levels, which ultimately leads to interruption of crusher operation. Coal crushers in power plants are nor-mally elevated in the structure. A proper conventional foundation design demands a thorough dynamic analysis of the foun-

In Mineral Processing Design and Operations (Second Edition), 2016. 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.
Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at
The crusher is one component of the circuit. As such, its performance is in part dependent on the proper selection and operation of feeders, conveyors, screens, supporting structure, electric motors, drive component and surge bins. Where used, attention to the following factors will enhance crusher capacity and performance.
