Mini Roll Compactor Machine

Nemarit Engineering Pvt. Ltd. is a leading manufacturer, supplier, and exporter of Mini Roll Compactor Machines engineered for laboratory-scale dry granulation, product development, and research applications in the pharmaceutical, chemical, nutraceutical, cosmetic, and food industries. Our compact and GMP-compliant machines are designed to produce uniform granules with minimal material loss, making them ideal for formulation trials, pilot batches, and R&D environments.

Manufactured using high-quality SS 304 and SS 316 stainless steel, our Mini Roll Compactor Machines deliver precise compaction, consistent granule quality, and reliable performance. With over 40 years of inherited engineering expertise, Nemarit Engineering provides innovative processing solutions trusted by customers across India and global markets.

Features

Roll Compactor KSD-RC 200/50, 200/75 & 200/100 are GMP Models & 200/150, 200/200 are Standard Models (can be supplied as GMP at extra cost).
Very compact design available in Plain, Water Jacketed or Flameproof Model.
Screw is driven through VFD. Safety slipping clutch between gearbox and feed screw.
Rolls drive through twins shaft gearbox with speed drive unit coupled to it using coupling, which ensures synchronization of the rolls with a steady torque loading.
Pre-densifier screw comprises of cylindrical or conical shape, which is well polished and made of AISI SS-304 quality material – SS 316 optional.
Compacting rolls sleeves are made out of tool steel, hardened to 55 HRC approximately, and are keyed in to shafts and thus protected against axial slipping by thrust plates and bolts.
The feed screw assembly can be lifted by hand-operated hydraulic pump. This facilitates ease in cleaning.
Scrapper assembly also designed to dismantle for ease of cleaning.
Pre-compression chamber guides the powder without any slippage or leakage.
A separate panel board which consist all controls and indicators of the compactor are permanently built in namely, on/off rolls, on/off feed screw, main switch, forward/reverse switch, ammeters for rolls and feed screw and emergency stop to avoid short circuit or fire hazard at the time of cleaning with water.

Water Jacketing System to be used considering the below points:

Water should enter in the water-jacketing system with gravitational force and the inlet of water must be parallel to it.
The force of inlet water should not be high, it must be normal.
The volume of inlet and outlet should be equal it means if outlet volume is one liter in 10 min. then inlet volume should not increase than 1 liter in 10 minutes.
Force of inlet water should be controlled through appropriate valve between inlet of water- jacketing system and your source of water supply.
Outlet water from water-jacketing system must not be re-circulated to avoid backpressure to the seals and it should go to drain only.
Always supply raw water to the water-jacketing system as it is require maintaining the temperature between two rolls while compaction.
Don’t supply chilled water as it will condensed to rolls and shafts because the area, where the machine will be installed, will be air conditioned and also Rh must be maintained.
If above points are considered and implemented during the installation of the machine, the problem of leakage from the water-jacketing system should not occur.
