Comprehensive Wood Crusher For Shredding Waste Pallets

The comprehensive wood crusher, namely the scrap wood shredder, or waste wood pallet grinder,  is a large and medium-sized continuous crushing equipment, mainly used to crush and recycle various waste packaging wooden boxes, waste wooden furniture, waste building templates, nailed wood scraps, waste wood pallets, branches, logs, hardwoods, etc. This continuous pallet crusher machine can quickly crush all kinds of scrap wood wastes into scraps.

The wood chips and sawdust processed by the comprehensive pallet crusher can be used for papermaking, power generation, and processing into biomass pellets. This kind of continuous wood crushing equipment is often used in various large construction factories, farms, forest farms, etc. to recycle all kinds of wood.

1. The conveyor helps to feed the raw materials into the machine more easily. The raw materials can be loaded onto the conveyor manually or placed on this conveyor using a wood grab/loader.

2. The feed roller is installed at the feed port and is controlled by the hydraulic system to move up and down to adjust the feeding capacity. When the raw material comes from the feed conveyor, the teeth on the feed roller swallow the raw material into the feed chute and send it to the knife roller.

3. The knife roller is installed in the center of the machine and rotates with the main motor. There is a cutting blade on the knife roller. There is a fixed lower blade on the frame of the biomass crusher. When the raw material comes to the knife roller, both the rotating blade and the lower blade cut it.

4. Equipped with a hydraulic oil station to control the feed roller so that it can lift the feed chute slightly to make it easier to enter larger-sized raw materials, and then the upper plate of the chute slowly falls to protect the feed roller.

5. The wood chips/EFB fibers will fall onto the screen and be discharged from the holes on the screen to the discharge conveyor.

6. The machine is equipped with a 12-meter-long discharge conveyor.

7. The biomass crusher is equipped with an electrical panel through which the start and stop of the main motor, feed roller motor, feed conveyor motor, discharge conveyor motor, and hydraulic system motor can be controlled.

Comprehensive crushers have a variety of crushing methods, mainly including extrusion, splitting, breaking, shearing, impact, or striking. These crushing methods are often mixed with multiple action modes to achieve the best crushing effect.

Extrusion crushing: The working surface of the crushing machine applies pressure to the material sandwiched between it. When the compressive stress on the material reaches its compressive strength limit, the material will be crushed.

Splitting and shearing crushing: The edge of the crushing working surface wedges into the material to generate tensile stress inside. When its value exceeds the tensile strength limit of the material, the material will split and produce powder locally at the contact point between the sharp edge and the material.

Impact crushing: This is a commonly used crushing method in comprehensive crushers. The impact of the high-speed moving crushing body on the crushed material, or the impact of the high-speed moving material on the fixed wall, as well as the mutual impact between the moving materials, will cause the material to be crushed.

Feeding: The material first enters the crushing chamber through the feeding device. The design of the feeding device needs to ensure that the material can enter the crushing chamber smoothly and evenly to avoid blockage or overload.

Crushing: In the crushing chamber, the material is subjected to multiple forces such as extrusion, splitting, breaking, shearing, and impact, and gradually crushed into smaller particles. The crushing chamber is usually equipped with crushing teeth, crushing hammers, and other crushing elements, which crush the material through high-speed rotation or reciprocating motion.

Screening and discharging: The crushed material needs to be screened by the screening system to meet the needs of different users. The screening system is usually located below or on the side of the crushing chamber, and the material is separated into particles of different sizes by vibration or rotation. The screened material is discharged from the crusher through the discharging device to complete the entire crushing process.

1. Straws and agricultural residues: crop straws, rice straws, crop shells, and waste residues from the processing of agricultural and sideline products.
2. Trees and cutting and processing residues: piles, branches, roots, leaves, etc. of various trees, as well as wood shavings, wood chips, broken wood, and other forestry processing wastes.
3. Dismantling of used formwork and wooden pallets: various specifications of used formwork, formwork fragments, building formwork with nails, waste wooden furniture, wooden pallet dismantling brackets, etc.
