Roll Compactor Machine

Roller Compactor & Roll Compactor Machine is used for dry granulation method. It forces the fine powders between two counter rotating rollers and presses the fine powders in a solid compact or sheets, so called chips or flakes. Finally these chips or flakes are then reduced in size to the desired granules/grain size further with the help of Oscillating Granulator Machine or Multi Mill Machine or Comminuting Mill or Sizing Machine. The sieve size should be selected very carefully in order to prevent the generation of fines. The selected sieve defines the final granules/grains size. Also further to achieve excellent granules/grains can be made dust free by Screening (Sifter) Machine. The separated fines also can be Re-compacted/ Recycle with Roll Compactor Machine.

In the process of compaction the fine powder or crystalline powder are fed to the charging hopper of the Roll Compactor. Here the vertical feed screw feeds the powder into the compacting zone of the compacting rollers through the pre-compacting chamber. The adjustable speed (through AC Variable Frequency Drive - AC VFD) of feed screw pressures the powder to pass strictly between the compacting rollers gap and therefore strong/hard chips/flakes forms from the fine or crystalline powder. After proper synchronization of Roller Speed & Feed Screw Speed with proper flakes quality, the same speed

Ratio can be continued to achieve the more output (if the speed limit permits the machine rated roller & feed screw speed) from the same machine model.

The Roller surface can be selected depending upon the characteristics of the powder/product. If the products are well familiar with the Roll Compactor Machine, our Technical Team can suggest the perfect roller surface for the particular product base on an experience & expertise for it. For product development or evaluation of product or changing the concept of granulation method, or achieving the dust free granules in order to get the Export quality granules, we are always happy to carry out the trails with your material in our plant.

Silent Features

CPM Roll Compactor CPM -RC 200/50, 200/75 & 200/100 are GMP Models & 200/150, 200/200.
Very compact design available in Plain, Water Jacketed or Flameproof Model.
Screw is driven through ACVF Drive. Safety slipping clutch between gearbox and feed screw.
Rolls drive through twin's shaft gearbox with speed drive unit coupled to it using coupling, which ensures synchronization of the rolls with a steady torque loading.
Pre - den sifter 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, and 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.
Electrical interlocking between main roll drive and fixed screw drive.Water jacketing arrangement. (optional)
Hydraulic power pack system for Rear Roller. (optional)
AC Variable frequency drive for Rollers. (optional)
