Drum chippers

The series of OKRR drum chippers includes stationary chippers with electrical drive designed for chipping woodwaste from sawmills and carpenters' shops into high-quality technological, fuel and smoke chips, regardless of material humidity. Normally, those chippers are fitted with vibrating feeders providing automatic and safe feeding of woodwaste to a chipper inlet. Chip size depends on a number of knives in a drum and on perforation of a screen mounted under the cutting head. The chippers are also fitted with anti-overload system preventing machine to be stopped if too large portion of woodwaste is fed.

Basic unit, which is adapted to pneumatic collection of chips, consists of a chipper, a vibrating feeder, a control box (based on electrical components made by Siemens and Eaton) and a separate control panel. As an option, those chippers can be fitted with an inverter to adjust feeding speed of the material used. As a result, chip length can be adjusted. Chippers can also be optionally fitted with chip collection system based on drag chain conveyor made according to parameters given by a customer.
