Roll Compactor cGMP

Roll Compactor Machine also called as powder compactor/granulator 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 continue 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.
