Introduction of Drum Wood Chipper
Drum wood chipper is a special equipment for producing wood chips, which is widely used in the wood processing field such as in paper mills, particleboard factories and fiberboard factories.
The machine mainly crushes the peeled round wood, diameter wood, branches, boards, bamboo and other large pieces of raw materials into wood chips or wood chunks of size 20-30mm, so it is also widely used in the initial part of some biomass pellets (wood chips pellets, bamboo chips pellets, etc.) pelletizing sets of equipment.
- Application Materials: The drum chipper for wood chips can cut logs, branches, board veneer, waste veneer, bamboo, cotton sticks and other non-wood fiber stems into chips of certain specifications, which can be used as the basic raw material for at least particle board, fiber board, non-wood artificial board and pulp and paper making.

Mobile Drum Wood Chipper For Sale
Mobile drum wood chipper is a new type of mobile equipment manufactured on the basis of drum wood chipper, today we share with you the structural composition of mobile drum wood chipper, hope it will be helpful to you.
The mobile drum wood chipper is mainly driven by a diesel engine, which solves the difficulties of the original power shortage or the lack of electricity in the mountains. The machine is equipped with four tires at the bottom, and the tires are interconnected with the traction frame, which is convenient for mobile operation and flexible transfer.
The mobile drum wood chipper is mainly composed of feeding conveyor, hydraulic feeding device, knife roller, blade, bottom discharge, etc. The machine can be installed in the discharge part of the discharge conveyor, which is convenient for transporting the processed wood chips out to the truck.
Start the diesel engine, the machine starts to work, we will put the wood or bamboo into the feeding conveyor by claw machine or manual work, the wood or bamboo through the belt or chain plate intelligent transport to the feeding pressure roller extrusion crushing, after crushing the wood through the knife roller on the blade repeated cutting operation, be cutting processing into wood chips, wood chips then out of the discharge port.
Working Principle of Wood Chipper Machine
The machine is composed of machine base, knife roller, upper and lower feeding roller, conveyor belt, hydraulic system and other parts.
The machine base is made of welded steel plate with high cavity degree, which is the supporting foundation of the whole machine; two flying knives are installed on the knife roller, and the flying knives are fixed on the knife roller with specially manufactured flying knife bolts through the pressure block; according to the different thickness of the raw materials to be cut, the upper feeding roller assembly can float up and down within a certain range with the help of the hydraulic system; the qualified chips cut down fall through the mesh sieve holes and have the bottom row, and the large chips will be cut in the The large chips will be cut again in the machine.
The wood enters the chipper through the conveying system and feeding port in the high-speed rotating flying knife and the bottom knife mounted on the machine base to form shearing side effects, and is chipped into wood chips, and the chipped qualified wood chips leak down through the screen holes below the knife roller and are output by the discharge system. A few larger chips, which cannot pass through the screen holes, continue to be driven by the rotating knife rollers and are crushed again by hitting the crushing rod.
Advantages of Drum Chipper Shredder
- relatively large feed opening, wide range of applications, in addition to cutting small diameter wood, wood harvesting residues (branches, twigs, etc.) and wood processing residues (bark, slats, log cores, waste veneer, etc.), can also be used to cut non-wood materials (such as sisal, reeds, bamboo, etc.).
- advanced equipment structure, automatic feeding, continuous operation, can be used in conjunction with shredders, etc., to produce high-quality wood chips and sawdust.
- large production capacity, high quality of cutting chips, easy operation and maintenance.
The Difference Between Drum Chipper and Disk Chipper
First of all, from the price point of view, the price of drum chipper is much more expensive than disk chipper. A disk chipper can be bought for a few thousand dollars, while a drum chipper often costs tens of thousands of dollars. But price is not the main basis for judgment when buying and selling, it is fundamentally necessary to start from the actual needs. Drum chipper can cut small wood, board skin, slats, etc. with a diameter of 45 cm or less, so if the diameter of raw materials is small or the size is different, you should buy a drum chipper.
Drum chipper has the characteristics of small investment (minimum thousand dollars can be bought) and high return. It is widely used in paper, pulp and wood-based industries. The size of wood chips can be adjusted by screen, but for too thick and too fine wood, the wood chips cut by disk chipper will have uneven size, and its slicing effect and efficiency are far inferior to drum chipper.
For example, in the production of fiberboard and particle board, there are often fixed requirements for the length of the wood chips, while the disk chipper can easily adjust the length of the wood chips, so the disk chipper has a wider cutting range than the drum chipper. The quality of wood chips cut by the disk chipper is also better than that of the drum chipper because the drum chipper will squeeze the raw material before cutting, thus making the wood split, which is done to improve efficiency and reduce power consumption.
Tips for Using Drum Chipper
- Before installing the drum wood chipper, the place of use should be leveled and, if possible, hardened. In order to place the equipment smoothly, the installation direction should be determined according to the actual conditions of the site and raw materials.
- Check the circuits and oil lines to confirm that they are safely connected. In future use, the tension of each chain, v-belt and drive mechanism should be checked frequently.
- The blade of the wire stripper is an alloy steel product. After long time use, if wear or change the angle, you can loosen the fastening screw of the blade, and you can remove the blade for grinding and adjustment.
- When connecting power to the drum wood chipper, connect 380V three-phase power from the distribution box or distribution cabinet. First, check if there are any debris and branches around the equipment to affect the operation. After turning on the power, first determine the rotation direction of the feed rollers and make the equipment run left and right for 5 minutes, listen and observe if the equipment is abnormal.
- At the beginning of the trial run of the drum wood chipper, several straight woods of about 2-4 meters in length within the processing range should be selected according to different models of small, medium and large sizes. Try to avoid using special hardwoods and large diameter and excessively bent raw materials to test the machine.
- Hold the material with both hands when feeding, first lift the end of the material so that the front end presses the feed roller into the feed roller, then you can release your hand when the end of the feed roller clamps the wood and starts to discharge. The material receiver should support the wood with both hands and move in the direction of the discharge, especially if the wood is about to be stripped and completely separated from the discharge rollers.
- When using the drum wood chipper, first check the operation direction of the main machine and the inlet and outlet system, check whether the control handle of the hydraulic system is flexible, whether the lift of the oil cylinder is synchronized and free, and whether the pressure is normal. Displacement of the manual oil pump and electric hydraulic oil pump is within the specified range. Open or close the valves in the oil circuit of the equipment as needed.
