wood waste
Wood waste is a common type of solid waste in urban construction and industrial production, mainly including discarded furniture, construction templates, wooden pallets, and branches. This waste is bulky, lightweight, and presents high collection and transportation costs and significant processing challenges.
I. Working Principle of Wood Waste Sorting Machines
The entire sorting process typically includes Shredding, screening, magnetic separation, air separation, and intelligent identification.
The entire system is designed based on the principles of crushing, volume reduction, sorting, and transfer. It employs a dual-shaft crushing and volume reduction machine, a magnetic separator for iron removal, eddy current separation for non-ferrous metals, and an air separator for sorting lightweight materials such as sponge, fabric, and wood.
II. Application Areas Of Wood Waste Sorting
Wood waste sorting machines are widely used in large-item waste treatment centers, construction waste recycling projects, and wood processing parks.
Taking the Quzhou Renewable Resources Recycling Project in Zhejiang Province as an example, this project uses intelligent sorting robots to sort wood from waste, achieving waste reduction, harmlessness, and resource recovery.
III. Main Sorting Technologies and Equipment
1. Shredding Equipment
Shredding is the first step in wood waste processing. Twin-shaft Shredders use two opposing rotating cutter shafts to shear, tear, and compress materials, reducing large pieces of wood waste to a manageable size. They can process wood waste with a diameter of less than 300 mm, with a processing capacity of 3-10 tons/hour.
2. Screening Equipment
Common screening equipment includes:
Trommel Screen: A rotating cylindrical screen separates materials into multiple grades based on particle size. For example, the design in the wood chip sorting component patent uses multi-segment screens with different mesh sizes for efficient wood chip grading.
Vibrating Screen: Driven by an unbalanced motor or electromagnetic drive, it adapts to screening needs across different particle size ranges.
3. Air Separation Equipment
Air separation utilizes the density differences of different materials in an airflow to effectively remove lightweight materials such as sponges and fabrics from wood waste.
4. Intelligent Sorting Equipment
With the development of artificial intelligence technology, intelligent sorting robots are playing an increasingly important role in wood waste sorting. The AI sorting robot employs a self-developed Cartesian coordinate mechanical structure, combined with multiple algorithm models and motion control models, and leverages a rich sample library to achieve a sorting rate of over 96%, effectively sorting materials such as wood blocks and planks.
5. Hydraulic Sorting Equipment
For wood waste mixed in complex construction waste, hydraulic sorting is an effective method.
