DRUM CHIPPER - DPF
DEMUTH DPF Drum Chippers are extremely simple machines with updated constructive characteristics, which to considerably increase efficiency and durability. The machines were projected after observing and using several equipament in operation. Considering that drum chippers are equipment initially used in countries of essentially tropical woods, they were properly projected and the experience proved to be machines of very long durability, high versatility and low maintenance.
Several items guarantee operational security to the equipment:
- Mechanical device, with hood bearings, rotor and counter-knifes locking;
- Electrical sensors to avoid involuntary motor starting;
- Hydraulic valves for immediately blocking in case of piping damage.
BASE FOR MOTOR
Starting base for motors with power over than 150 KW are provided with motor pulley between bearings and elastic coupling to get an efficient power transmission.
The rotor structure is extremely sturdy with a project that reduces the superficial wearing. The knives fixing is done through overdimensioned clamps and screws that avoid any knife return possibility, whichever material is processed.
Rotor is fixed at the shaft through pressure conical rings.
Built-in and strongly fixed to the main frame, assuring more stability during re-chipping process.
Useful and re-sharpened on four sides, the first counter-knife is easily removed and of quick change concept, eliminates any position check needing. Bi-parted comb with interchangeable counter-knife clamp.
Feeding rolls with interchangeable segments manufactured in structural quality steel that guarantee simplicity longer useful life changing agility.
