The driving force from the electric servo motor is transmitted to the pressing mold via the linking mechanism by a rotation to reciprocation conversion assembly. By virtue of the provision of these, the mold-pressing apparatus can very easily and effectively secure the applicable pressure and adjust the pressure-applying speed, stroke of the pressing mold, and the pressing time so that the mold operator can create a comfortable environment and improve overall efficiency of the pressing operation.

Abstract: A rotary pelletizing machine has a rotatable matrix disc, a plurality of vertically adjustable pressing rollers which control position of the upper and lower plungers, a drive for a height adjustment of the rollers, a housing accommodating the drive, and a bearing block supporting the pressing roller and releasably connected with the housing.
