Civil Engineering Practice
Capacity of Roll Crusher • The capacity of a roll crusher will vary with: • The kind of stone • The size of feed • The size of the finished product • The width of rolls • The speed at which the rolls rotate • The extent to which the stone is fed uniformly into the crusher. 18.
DESIGN OF MECHANICAL CRUSHING MACHINE
the carrying capacity of the vehicle and as the cans being an indefinite shape needs to me made into uniform shape and size for easy disposal. This is where the mechanical crusher comes in to play. The crusher would crush the cans thus reducing the gap between them and make them
Rock Crushers 911Metallurgist
Rock Crushers. The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small ...

How to Calculate Load Torque amp Motor Power
Mar 04, 2006 The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and …

Crusher Efficiency Calculations
Sep 15, 2014 A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough.
Construction Working and Maintenance of Crushers for
When a closed circuit system (detailed in next section) is not desirable to control top size. Shear Shear consists of a trimming or cleaving action. Shear is usually combined with other methods. For example, a single-roll crusher, employ shear together with impact and compression.
