Roll Compactor



“shiv” Roll Compactor is designed for the densification and granulation of powder for the pharmaceutical industries in particulars and food and chemical industries in general. It is also ideal for batch or continuous processing variety of materials.


  • “SHIV” Roll Compactor SPERC 200/50 & 200/75 is GMP models. Totally enclosed with SS304 cladding and frame work – ease of cleaning.
  • Very Compact Design available in plain, water jacketed or flame proof model.
  • Screw is driven through variable drive safety sleeping clutch between gear box and feed screw.
  • Rolls drive through twin shaft gear box with speed drive unit coupled to it using a flexible coupling which ensures synchronisation of the roll with a steady torque loading.
  • Feeding device and sealing of roll by means of check plates and all parts which are exposed to wear are made of hardened steel. The compacting head is two piece assemblies for easy dismantling.
  • Pre- densities screw comprises of cylinder or conical shape which is well polished and made of AISI SS-304 quality material.
  • Compacting rolls sleeves are made out of tool steel, hardened to 55 HRC approx., & are keyed into shaft & thus protected against axial slipping by thrust plates & bolts.
  • The feed screw assembly can be hydraulically lifted by hand – operated hydraulic pump. This facilitates ease in cleaning.
  • Scrapper Assembly so designed to dismantle for ease of cleaning.
  • Pre-Compression chamber guides the powder without any slippage or leakage.
  • The main roll drive & feed screw are electrically interconnected.
  • All controls and indicators of the compactor are permanently built-in namely, on/off rolls, on/off feeds screw, main switch forward / reverse switch, ammeters for rolls & feed screw & emergency stop


By virtue of its construction and design, it ensures easy and quick clean-up and is most ideal for quick product change-over and also prevents contamination from one product to the other.

Jacketing is provided in all process sensitive area like rolls, bowls hopper. Quick release coupling are provided with non-return valve to avoid spillage of water/liquid while taking hopper & bowl for cleaning & sterilization.

The mini roll compactor is totally based on dry method of granulation. Powder charged in the Hooper is pre compacted and fed in to the gap between two compacting rolls. The rolls process the powder in to the compacted sheet which can be granulated in to desired mesh size with the use of granulator.


  • To improve bulk density
  • To achieve better granulation of sieve analysis
  • To reduce process cost and improve end product quality
  • Compacted granules required smaller size of capsiles.
  • Dust or fine powder is less in compacted granules.
  • Compacted granules are free flowing and reduce the packing size.
  • It can be used as dry method of granulation.


  • The compacting roll is designed to provide a uniform force distribution by means of hydraulic compacting force thus granules of equal quality are produce.
  • Electric control panel is totally separate from the machine.
  • The feed screw assembly can be hydraulically lifted by hand operated hydraulic pump. This facilitates ease in cleaning.
  • The compacting roll is cooled by a water circulation system.
  • Versatile quick test for dry granulation characteristics.
  • The test can be run with only a few hundred grams of material.
  • The results obtained can be extrapolated to a production size machine.
  • Compact & Portable design allows mobility for testing at a convenient place.
  • Speed of D.C. motors can be varied to control compaction force and out-put
