Roll Crusher - an overview | ScienceDirect Topics

Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions. Normally, one roll is fixed while the other roll is movable against spring pressure.

Crushing Principles of Mechanical Crushing

Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material.

DESIGN OF MECHANICAL CRUSHING MACHINE

3. OPERATING MECHANISM This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive. This pulley gives rotary motion to the transmission
