A tree log is inserted into the hopper and started into the chipping mechanism. There are grooved rollers equipped in the throat of their feed funnels. Once a tree log has been gripped by the rollers, the rollers transport the tree log to the chipping blades at a steady rate. These rollers are a safety feature and are generally reversible for situations where they gets caught on clothing. Finally, the tree log is shredded into smaller chips.

1. CE approved by SGS.
2. Our machine base is welded by 25-30mm thickness of manganese steel plate. The intensity and stability is much better than machine base produced by 12-20mm thickness steel.
3. Our knife-roller assembly use special welding and processing technology, make balance check.
4. Our feeding-roller use integral nodular cast part or split nodular cast part. The stability is much better than welded feeding-roller.
5. Our feeding-roller use K-series spiral bevel gear reducer or FA-series parallel shaft gear reducer. The transmission torque ability is 40% higher than cycloidal pin wheel reducer. The price of our reducer is 3-4 times of cycloidal pin wheel reducer which other manufacturer use.
6. Our conveyor is made by 4mm steel plate and channel steel welding and our roller use casting parts or seamless steel tube.
7. About bearings, we mainly use NSK,SKF or joint venture brand.
8. Our hydraulic system use standard hydraulic pump station or electric oil pump. The structure and design is reasonable and orderly.

HC-BX216	55	650	8-10	180*500	120
HC-BX218	110	800	15-20	225*680	160
HC-BX2110	220	1000	70-75	330*1050	210
HC-BX2113	315	1300	100-108	400*1050	230

Remarks:
The above capacity comes from wood chipping production.
The final capacity of Drum Chipper depends on the features of raw materials, operation and maintenance,etc.
