Heinrich Dreher GmbH & Co. KG products

Proven drive without gear. Production rationalization by in line granulation of scrap material. Easy cleaning and quick screen changing. No adjustment of rotor cutting blades. Regrindable cutting blades, high economy. Solid rotor with high rotation torque. Oversized double sided bearing. The electrical safety interlock ensures a rotor stop when opening the granulator

Inclined position of cutting chamber, especially designed for bulky parts. Low infeed height. Comfortable and efficient cleaning of cutting chamber due to swivel-type. Easy screen change because of swing-type design. Resistant to fracture and reliable on operation even in constant working, due to the use of high quality raw materials. Rotor with high rotative moment and oversized rotor bearings.

Rotor dynamically balanced for life time in turbine quality. Solid rotor with high torque moment. Easy and quick removing of screen without using any tool . Solid steel-flanges with external bearing. Complete soundproof-cabin made of no combustible material. Conveyor belt (option).

Resistant to fracture and reliable in operation even in constant working due to the use of high quality raw materials. Cutting rotor with high rotative moment and oversized bearings at  both sides of the rotor. Universal hopper for feeding by hand or by conveyor belt. Risk less easy opening of top part guaranties a quick and easy cleaning. Easy replacement of screen

Two steps – one feeding. Precutting and grinding in only one machine, without intermediary transportation and new feeding. Saving time, space and energy.

DREHER Granulators for profiles - effective profile-granulation without precrushing. The powerful self feeding realises high throughput rates by less energy consumption. Because of the small headroom and the compact construction our profile Granulators can easily be adapted in the production process. The stable design assures a failure-free operation.

These Heavy-Duty Granulators, have been specially designed for the economical granulation on thick walled sections such as tops and tails, chunks, extruder discharges, thick walled sheeds, pipelines, etc..

Absolute saftey for the operater and the machine. Our electric controlled, hydraulic operated horizontal-intake-systems for HZ-Granulators are safe-guarding man and machine, this further results in more effective and efficient machine operation, with reducted man-power attendance requirment and also in reduced electrical power consumption.

Wear resistant feeding zone and cutting chamber. Easy rotor replacement and cutting blade adjustment due to the pivotable infeed roll. Drive and infeed speed stepless adjustable by frequency regulation. A solid and high quality construction ensures an optimum quality of the granule. Easy maintenance and cleaning.

DREHER Band Pelletizers, for a rational granulation of thermoplastics. Reliable tape-infeed until hand over by coupled feeding system with adjustable roller-pressure. Feeding rate infinitely variable on customers demand. Highest reliability. Exactly diced granulate and highest performance due to slotted knives.
