Insmart Roll Crusher

For fast and effective reduction of feed material by crushing between the rolls.

Principal of operation:

The hard and brittle geological materials are trapped between the two rotating grooved rolls. One of the roll is given power through a “V” belt pulley system and is fixed on a stationary bearing block. The gap between the roll can be adjusted by a spring loaded screw rod. After the desired gap is adjusted the position is locked by a lock nut.
High pressure Roll Crushers having constant preset load with high pressure hydraulic accumulator are also manufactured.
Provision is made to change the speed of roll electronically.

  • Ideal for secondary crushing of the ores/minerals like: Magnetite, Hematite, Laterite, Limestone, Bauxite, Manganese Ore, Quartz, Chromite, etc.
  • The crushing is due to entrapment of particles between the rolls thereby the particle gets ruptured this also facilitates low energy consumption during grinding.
  • Unique design that operates two rolls with single drive.
  • Insmart Roll Crushers have got a unique facility of gap adjustment by two screw mechanism that can easily change the nip angle for getting the desired reduction ratio.
  • Firm design does not require any foundations and gives customer a freedom to shift the equipment as per the requirement.
  • A range of roll crushers are available to crush with a feed size range of -20 to -3 mm size.
