Sawdust making machine

Types of sawdust making machines

Sawdust refers to the tiny wood pieces and shavings produced during the cutting, drilling, and sanding of timber and wood products. It is a diverse raw material with multiple applications. Hence, the sawdust making machine has gained significant prominence in the wood processing industry.

Various types of sawdust-making machines are available to produce sawdust from different feedstock:

• Wood Crusher Machine:

  A wood crusher machine is designed to reduce whole logs, branches, trees, and leftover boards to wood chips or smaller wood pieces. This heavy-duty machine utilizes high-speed rotary blades or hammers to crush the wood material into finer particles. The produced sawdust serves as fuel in biomass power generation or is further processed to manufacture wood boards.

• Hammer Mill:

  A hammer mill is a widely used wood processing machine that can crush various types of wood into uniform sawdust. Hammers, which are the main components, strike the wood material at high speed. The impact and shear forces reduce the wood into smaller particles. The size of the sieves and screens used will determine the final sawdust particle size.

  A wood hammer mill functions well with wood leftover from furniture making, such as wood strips, as well as softwood like pine, fir, and birch. Buyers can choose the proper screens or sieves to get different sawdust diameters.

• Wood Shaving Machine:

  By using a wood shaving machine, buyers can create both sawdust and wood shavings. This machine processes wood material into long shavings or curly pieces through a planing-cutting method. A wood shaving machine is preferable for use with hardwood, such as rubber wood and oak, and is usually adopted in an animal bedding manufacturing plant.

• Wood Pellet Machine:

  A wood pellet machine offers another solution for producing sawdust. This machine compresses the sawdust and wood fibers into wood pellets, small cylindrical pieces.

  The advantage of a wood pellet machine is that it can produce sawdust on demand. Moreover, the sawdust particles will be smaller and easier to transport.

Specifications and maintenance of sawdust making machines

Wood sawdust-making machines' specifications vary depending on their types, models, applications, and manufacturers. Here are some typical specifications to consider for wood sawdust-making machines.

• Sawdust making capacity

  The machine's size and capacity vary depending on the machine type. For example, a wood crusherТип 1模型 may process wood waste of between 3000 and 13000 kg per hour to produce sawdust. A sawdust machine with a bigger capacity will most likely have a larger intake space and a more powerful motor.

• Sawdust sizes

  Different wood sawdust machines produce sawdust of different sizes. Some sawdust may range from 2 to 5 mm in diameter, while others may range from 0.5 to 3 mm. A sawdust machine that produces sawdust of smaller sizes will have finer screens and blades.

• Power requirement

  The power requirement of a sawdust machine will depend on the motor's power. It will range from 3–15 kW. A sawdust machine that produces a higher capacity will have a higher power requirement.

• Feeding

  A wood sawdust maker machine can have different feeding mechanisms. For instance, it can be a hopper or a conveyor. Also, the feed sizes may vary from machine to another. Some may have an entry diameter of 40 mm or more.

• Dust collection

  Most sawdust machines have dust collections to collect dust as byproduct during wood processing. The dust collection allows a cleaner work environment. Depending on the size and type of the machine, it can have either single or multiple dust collection systems.

• Powder source

  Generally, the power source of sawdust-making machines falls into two categories - electric motors and gasoline engines. The electric motor type is ideal for use in indoor settings due to its quiet operation. On the other hand, the gasoline type is suitable for use in outdoor applications, where electricity is not available.

With proper care and maintenance, a sawdust-making machine can serve a person for many years. Regular maintenance can help prolong the life span of the machine while preventing untimely breakdowns. When not in use, store the machine in a dry place and keep it out of dust and sunlight. Avoid overloading the machine. Overloading may result in motor burning and damage to the blades. Always clean the machine after use to prevent residue and sawdust buildup.

Schedule for professional maintenance, inspection, and repairs periodically. Regular blade sharpening helps maintain the machine’s cutting efficiency. Additionally, lubricating moving parts of the machine reduces friction and helps prevent wear and tear. Replace the dust bag or filters in the dust collector to prevent clogs or restricts air flow.

Applications of sawdust making machines

Impelled by the ever-growing need for renewable, green energy and a decrease in waste, the wood-pellet sector has flourished. Consequently, this has caused a surge in the demand for sawdust-making machines, powerful enough to create significant quantities of sawdust, which can then be transformed into wood pellets using a wood pellet machine for fuel.

The demand for sawdust machines goes beyond the production of wood pellets. Other industries are dependent on the consistent production of sawdust as an essential raw material. The MDF industry has a constant need for sawdust, as their primary raw material for production is essentially sawdust. This also extends to other industries such as the particle board production industry, the paper and pulp industry, and even the animal bedding industry, to name a few.

With the rapid urbanization sweeping through many regions, one can see the increase in the construction industry. The construction industry makes use of a variety of wood, which often produces a large amount of wood shavings. Wood shaving machines are pivotal in ensuring that precious resources, such as wood, are fully utilized by transforming the waste into useful products such as wood shavings. In addition to the construction sector, other industries, such as carpentry and furniture-making businesses, are constant producers of wood shavings and sawdust. These industries also rely on wood-shaving-producing machines to reduce waste and increase their profit margin.

As society strives toward a more sustainable and eco-friendly future, machines that produce sawdust and wood shavings have become essential in many industries.
