Communiting Mill

Latest improvements in design makes this unit a truly GMP model and versatile in Operation & Maintenance. Unit consists of S.S. 304 quality hopper, feed throat and processing chamber (can be provided in SS 316 quality at extra cost) with beaters assembly, heavy duty motor, starter with overload relay, three speed step pulley, suitable screen, SS cladded base having tabular legs with castors, optional jacket for the feed throat and processing chamber for cooling / heating.

 Operation :
  • Product kept in the hopper slides down to the enclosed chamber, where it is milled in between beaters and screen to the required mesh/micron size which can be collected at output container.
  • Quality and output depends upon the three main variables.
  • Beaters shape (knife / impact forward)
  • Speed
  • Screen size
 Application :
  • Mill has been specifically designed for wet and dry granulation, pulverization or dispersion of products or ingredients found in the Pharmaceutical, Chemical and Food Industries.
  • It is also find application in the Cosmetics, Confectionery, Fertilizer, Insecticides, Detergents and Electroflux Industries etc.
  • Knife edge for coarse or large particles and impact or flat edge for finer particles. High speed for grinding, low speed for coarser particles. A wide range of screens is available for various process needs.
 Salient Features :
  • GMP point of view machine is provided with SS cladding on base, SS belt guards, SS cover on motor & starter. No exposed painted surface of the machine. Motor rails, screw and guide rods are chrome plated.
  • Beaters assembly bearing are in a separate pillow blocks for ease in maintenance.
  • Very less down time as only beaters assembly will have to be reversed (and not the complete chamber) for making it knife to impact forward or vice-versa which can be done by single operator.
  • Fixed beaters assembly is provided as a standard supply which increases the output by 10 to 30 %, reduces noise level and is easy to clean as there are no cavities. (If product demands, swing beaters assembly can be provided.)
  • Beaters are stainless steel quality and fitted on a splinted shaft.
    Transmission of heat to the chamber from the bearings is minimum as there are away in separated pillow blocks. This facilitates to some extent in processing of heat sensitive product.
  • Beaters assembly is dynamically balanced which reduces vibration and noise level and increases bearing life.
  • Castors provided for mobility and brakes can be applied for fixing machine at one place.
    Machine is available in Plain & Water Jacketed model.
