Types of China Shredder Woods

A china shredder wood is a huge and powerful machine that breaks down logs into smaller wood pieces or chips. Various types of wood shredders exist on the market, each with a unique mechanism to reduce logs' size. Other types of wood shredders have specific characteristics, functions, and applications.

• Roller Wood Shredders: A roller wood shredder, also known as a drum chipper, shreds wood by using drums mounted on roller shafts to rip the wood apart. Roller shredders are built compactly to occupy a little more space than the standard size of the shredding drum. Because they have fewer moving parts, roller shredders are easier to maintain compared to traditional shredders. Also, roller shredders use less energy to operate. They are better options for shredding clean wood, such as pallets, boards, and battens, without metal contaminants.
• Single Shaft Shredders: This type of shredder has a rotor with one shaft fitted with knives. The knives on the shaft slice the wood against the stationary blades or anvil, thereby shredding the wood into smaller pieces. Single shaft shredders are versatile, and they offer a controlled shredding solution for numerous materials. They are great for shredding big volumes of waste materials, like pallets and wood boards, as well as other clean wood.
• Multi-Shaft Shredders: Unlike single shaft shredders with only one shaft, multi-shaft shredders have two or more shafts. The rotating shafts fitted with knives work together to slice and shred the wood. The power and efficiency of multi-shaft shredders increases with an increase in the number of shafts. They easily shred various types of wood, including contaminated wood with metals, such as MDF or particle board with metal fittings.
• Hammer Wood Shredders: A hammer shredder or hammer mills chops and breaks wood by using hammers. The hammers strike the wood more violently and repeatedly until it falls down into small pieces. Hammer shredders are most suitable for processing softer wood species. They produce finer end products. Many of them are blow-through designs that use air flow to separate the shredded materials.

Specification and maintenance

Annual specifications generally apply to typical types of shredders and may vary for specialized models and custom configurations.

• Wood Log Diameter/Length Range

Shredder manufacture specifies the diameter/length logs it can process. They may range from less than 100mm to over 1000mm. For example, a NESTO shredder has a tree length capacity of up to 800mm, and another one from Zhengzhou Yufeng has a log length capacity of 4000mm.

• Shredder Blade Type/Number

The blade types are generally one of the following: star-shaped, flat-lined, rolling, hammer, round disc, or customized. For example, an XRF shredder has a hammer-type blade with 72 hammers that can turn wooden waste into even finer particles. Another one has rolling-type blades.

• Power/Wattage

Power/Wattage indicates the motor's power output to shred wood. Power ranges from around 7,500 watts to over 150,000 watts, depending on the capacity.

• Output Rate/Wood Particle Size

The output rate at which wood waste is processed fluctuates based on the log diameter and type of blade. A wood shredder may produce wood particles ranging anywhere between sawdust and chip sizes. For instance, a Zhengzhou Gomine shredder could process 6 to 8 tons of logs per hour, producing particles the size of sawdust.

• Shredder Dimensions/Weight

An average dimension is about 2000*(L)*2000*(W)*4000*(H)mm. Overall dimensions and weights are considerably larger for industrial-scale machines and would typically require a heavy-load truck to transport.

Maintenance

The following are some routine wood shredder maintenance tips to prevent the equipment from breaking down, wearing out, and damaging faster than expected.

• Routine Checks:

Operators should examine the wood shredder regularly. They should check for minor things like loose parts, signs of wear, noise, or other alerts indicating the machine is not working correctly. They should always look at the output and see if there have been any changes that could suggest something is off with the shredder.

• Lubrication:

The wood shredder has several moving parts, and lubricating them reduces friction and keeps wear and tear low. Regular lubrication should keep the machine operating smoothly, and it should help extend its lifespan.

• Blade Maintenance:

Shredder blades cut wood into the desired size. Customers expect the output to be consistent. Hence, the blades must be in good shape. Check them for any signs of wearing out. Sharpen them as required, and clean them regularly to avoid buildups of residue that could affect performance.

• Follow Manufacturer Guidelines:

Every machine has specific requirements, and the wood shredder is no different. The operator manual should be followed so that maintenance and repairs are carried out according to the manufacturer's guidelines. The manual should also include suggested maintenance schedules and the number of repairs to be done.

Scenarios

• Furniture manufacturing:

  Furniture makers can use an industrial wood shredder to create waste seats and other trash. They put the shredder in their shop to reduce the space waste takes by changing it to a smaller size. All the chairs and other furniture items made from this recycled waste still look good and serve their purposes.

• Pallet recycling:

  Sidle Disassembly Pallet Shredder designs and builds recycling plants that can shred pallets used for shipping goods. The shredder breaks down old pallets into smaller wood pieces. After that, these pieces become raw material for making new wood products instead of sitting in landfills.

• Garden waste disposal:

  Homeowners with a backyard or a nursery can use a garden wood shredder to dispose of branches and trimmings efficiently and easily. Instead of sending everything to a landfill, they can turn it into mulch or compost. Smaller branches become wood chips.

• Bioenergy production:

  Wood shredders are used in the bioenergy sector to reduce wood waste, branches, trunks, and trees into small pieces used as biomass fuel. This fuel generates heat and power through combustion in power plants. The basic principle is to transform some natural trees into energy to feed other trees' growth.

• Plastic wood repurposing:

  Some plastic recyclers use a plastic wood shredder to dismantle used plastic products combined with wood fibers. An example is a composite made from fibers of recycled paper and wood. After shredding, the mixed materials go through the sorting process, where the different types of plastics get separated.
