Drum wood chipper is the ideal equipment for pellet mill production lines with high strength steel,double feeding system,it can be used to process logs,square blocks, branches,forestry waste,and fiber agro waste (such as sugar cane,hemp pole, reed stalks, bamboo, etc.)Wood chipping is the first step if you want to make wood pellets from logs. According to the structure of working parts, wood chipper is divided into disc wood chipper and drum wood chipper.

Remarkable Features of Drum Wood Chipper
* Wide application for wood materials chipping and biomass materials processing.
* Adopting the double roller feeding system, higher efficiency.
* With advanced structure and special blades layout, the drum wood chipper is suitable for undersized logs processing.
* Reasonable design, long service life and high work efficiency, logs and small wood are cut into high quality chips with even length and uniform chip thickness.
Drum Wood Chipper Structure
1.Drum chipper is made up of body, knife roller, feed roller, conveyor belts, hydraulic system and other parts. Its frame is made of welding high strength steel plate, which is the support basis of the whole machine.
2.The feeding roller can float up in a certain range with the help of hydraulic system according to the different chips thickness.
3.The hydraulic system: supply oil to cylinder by hand oil pump, you can start the cover shell for replacing the blades conveniently.
4.The top feeding roller can be uplifted when you maintain and repair this machine, which is convenient for adjusting the gap between fly blades and bottom blades, and dismantling the comb plate.

How to Make Wood Chips?
When transmitted to the chipping chamber by the transmission device through the feeding inlet, the material will be cut and sliced into wood chips by the blades, high speed flow and collision. In the process of blade cutting and grinding, the rotor produces high speed airflow and shocks repeatedly to accelerate material crushing rate. The qualified chips will drop out though screen mesh and discharge from holes on the screen, the larger material will be cut inside again.
Things You Should Pay Attention to
Drum wood chipper is named after the large, motor-powered drum located at the center of the machine. When the machine works, the process is very fast and loud, and carries significant safety risks. Any drum jam will affect the engine subsequently because the drum and engine are connected directly, meanwhile cause the engine to stall and pieces of wood to become lodged in the drum. So, the machine must be operated with care so as not to get clothing or appendages caught in drum, which can cause extreme injury or death.
