It is a rotary machine in vertical construction; fixed flat horizontal die gives it stability in operation. Unique feature of pellet press as compared to other densification is, it is not size specific. Any Pellet mill can give pellet output of 8mm – 25 mm dia. Die of different thickness can be accommodated in same frame with no effect on stability.

Vertical construction of pellet press, houses speed reduction unit at bottom of press. Three support vertical shaft is used to transmit power to pelletising rollers. 2-4 rollers depending upon size of unit, run at very slow speed on surface of fixed die and forces the material in die holes. In built lubrication is incorporated in small press while pressurized lubrication with optional cooling facility is provided in large units.

Power from electrical drive motor is transmitted to pellet press by belting.
