Energy and environmental technology, paper industry

Rollstar planetary gearboxes and hydraulic gear motors are as diverse as the industries in which they are used.

As the drive of the rotor turning device for turbines in the energy sector, conveyor screw or screw press for sludge dewatering in paper mills, shredders for tires or PET recycling in the plastics and rubber industry – all applications have one thing in common: The compact roller star drive generates maximum torques in the smallest space and adapts optimally to the needs of the system.

Tailor-made drive solutions Made in Switzerland

The large selection of modular gear stages offers the right solution for every requirement. If required, our in-house engineering department can provide further options that can be tailored to the application: holding brakes, sensors for speed monitoring, level indicators or gear shifting, to name just a few.

A typical fermenter drive for an organic fermentation plant. In this application, a four-stage planetary gear in plug-on design, combined with an electric motor for processing the biomass, ensures a maximum required torque of 360,000 Nm.

Drives in wood and cellulose processing 

Rollstar's offer covers a wide range of industries and applications: conveyor belts, agitators and mixers, rollers, lifting devices, sugar mills, platforms and much more. In wood and cellulose processing, our drives are used, for example, for wood conveyor chains.
