Roll Compactor Machine


Why Compaction Is Necessary
  • To improve bulk density.
  • To achieve better granulation of sieve analysis.
  • To reduce process cost and improve end product quality.
  • To produce uniform blends or mixture.
  • To produce a uniform particle size range.
  • To control particle hardness.
  • To control dust.
  • To adjust flow properties.
  • To improve solution or dispersion rates.
Principle Of Compaction
This is a dry granulation method. The basic concept is to force fine powder into solid compact or sheet. Some of the factors controlling the compaction process are roll surface, diameter, peripheral speed, separating force or pressure capabilities, feed screw and being processed. The addition of binders to the material being processed. The addition of binders to the material being processed greatly reduces the production of fines.

An Outstading Feature
Totally G.M.P., compact design-plain as well as water jacketed for products which are extremely heat sensitive. Various types of rolls can be offered to suit your specific application so as to achieve maximum bulk density of output eg. (A) Plain (b) corrugated (c) Briquetted & (d) knurled.

Specially designed feeding system consisting of hopper pre-densifier and a variable speed drive unit. Safety clutch is provided to prevent any accident.

Feeding unit can be hydraulically lifted by hand operated hydraulic pump for easy cleaning and built-in panel and indicators are provided, on-off, feed screw, main switch, forward/reverse switches. RPM indicators for roll and feed screw, emergency stop, digital RPM indicator etc.

Specially designed scraper is provided to prevent powder sticking on the rolls.

Design of the equipment is such that minimum lubrication is required in daily maintenance.

Main roll drive is designed with twin shaft gear box coupled with safety clutch to protect roll drive unit thereby perfectly synchronizing the roll with a steady torque.

The side seal is forced against the roll side, so that the percentage of uncompacted powder that leaks by is kept extremely low.

To prevent a possible accident the compacting roll is designed to rotate backward when cleaning.
