We develop and produce a wide range of Granulators and solutions according to special requirements of our customers. Serial production as well as specific customer requirements in connection to a favourable price-performance ratio are the decisive factors for our planning and manufacturing.

DREHER distinguishing points:
Smooth running and a low noise level are the result of a solid and compact constructed cutting chamber. The solid rotors, lathed and milled out of a full bar of steel have a high torque and avoid a deposit of the cut material on its surface. The cutting blades out of high-tensile steel are integrated in the rotor on their whole length and do not need to be adjusted, even after several regrind operations. Due to this the rotor will be lifetime dynamically balanced. The real helical cut with a constant gap between rotary and stationary blades over the whole length of the rotor causes low dust development and reduces the electrical power consumption. The oversized flanges increase the smooth running conditions and keep the noise level low. Optionally full soundproofing is available. The soundproof cabin keeps the noise down to a level of 85 dB(A). All Dreher granulator chambers can be opened at the middle of the axis of the rotor. This always guarantees an easy access to the cutting chamber in case of a change of the material. The screen can also be swung of which assures a quick cleaning of the rotor. During the whole operation period of our granulators Dreher guarantees a quick and efficient service.
