A screw dewatering machine is commonly used in the wood processing industry to separate liquids from solid materials. It’s called sawdust dewatering machine. This machine is especially valuable when dealing with wood chips, sawdust, or other wood processing byproducts that contain moisture.

Applications of Sawdust Dewatering Machine

Screw dewatering machines find extensive applications in the wood processing industry, including:

1. Wood Processing Plants: Wood processing plants often deal with significant volumes of sawdust and wood waste. Screw dewatering machines help dewater these waste materials, facilitating easier transportation and handling.

2. Wood Product Manufacturing Plants: These machines play a crucial role in the production of wood products like particleboard, fiberboard, and chipboard. Dewatering wood pulp enhances product quality and stability.

3. Biomass Energy Production: Wood waste is a vital resource in the biomass energy sector. Screw dewatering machines enable the dewatering of wood chips, lowering its moisture content, thereby reducing the cost of further processing, like drying. This process makes wood chips more suitable for biomass energy production, including biomass pellets and power generation.

4. Pulp and Paper Industry: Wood pulp is commonly used to manufacture pulp and paper products. Screw dewatering machines increase the concentration and quality of pulp by removing excess moisture, thereby improving the quality of paper products.

Working Principle

The sawdust dewatering machine is designed to remove moisture from sawdust and wood shavings efficiently. It consists of a rotating screw within a screen. The working principle of a screw dewatering machine relies on the power of screw compression.

When the wet material, such as wood chips or sawdust, is fed into the machine, the screw shaft begins to rotate. As the screw rotates, it compresses and conveys the material towards the discharge end. During this process, water is squeezed out through the screen, effectively separating it from the solid wood particles. The dewatered material is discharged at one end, while the separated liquid is collected for further processing or disposal. This dewatering process results in significantly drier and more manageable sawdust, making it ideal for various applications. Below is a video showing the dewatering process of spent grains.

Features and Benefits

1. Efficient Dewatering: Screw dewatering machines are renowned for their exceptional dewatering capacity. They rapidly extract the majority of moisture from sawdust, resulting in a drier product. This reduction in moisture content alleviates the weight of sawdust, lowers transportation costs, and enhances the efficiency of subsequent processing. Moreover, the dewatered sawdust enhances the quality of your final products, such as wood pellets or briquettes.

2. Energy Efficiency: Compared to traditional dewatering methods, screw dewatering machines typically consume less energy. Their operation principles lead to lower energy consumption, which is advantageous for reducing production costs and minimizing environmental impact.

3. Versatility: Screw dewatering machines are not limited to sawdust but can handle various wood waste materials, including wood chips, wood shavings, and particleboard scraps. It is also used to process other biomass waste, such as corn stalk, grass, waste food and vegetable, etc. This versatility makes them a valuable asset in various industry.

4. Environmentally Friendly: By reducing moisture content in sawdust, screw dewatering machines help reduce waste volume, thus lowering waste management costs. Moreover, their low energy consumption aids in reducing overall energy consumption, mitigating adverse environmental effects.

5.Durability: Typically constructed from high-quality stainless steel and carbon steel, these machines have a long service life. Their robust design can withstand high-intensity working conditions, reducing the frequency of maintenance and part replacements.

How to Choose the Right Sawdust Dewatering Machine?

When looking to invest in a sawdust dewatering machine, consider the following factors:

1. Capacity: Ensure the machine can handle the volume of sawdust your operation generates. Tianzhong Machinery offers various models with processing capacities ranging from 0.5 to 50 tons/h, allowing you to select one that matches your specific needs.

2. Energy Efficiency: Look for models that are designed to minimize energy consumption. Compared to other dewatering methods, such as centrifuge machine, screw press dewatering is much more energy-efficient.

3. Maintenance: Choose a machine with easy maintenance requirements and good customer support. Tianzhong Machinery’s designs include removable parts, like the casing, making cleaning and maintenance straightforward.

4. Versatility: Opt for a machine that can handle a variety of biomass materials and different moisture levels.
