Recently, Qingdao Sure Plastic Machinery has made a major breakthrough in the field of resource recycling equipment manufacturing. The test of its independently developed wood shredder has been successfully completed, opening up a new development path for related industries such as wood processing and wood-plastic product production. From the design dimension, this wood shredder adopts a standardized modular architecture design, and its parts have extremely high interchangeability, which is in line with the flexible production concept of Industry 4.0. According to actual operation and maintenance data statistics, compared with traditional equipment, its maintenance cycle can be shortened by about 30% due to modular design, effectively reducing the MTBF (mean time between failures) of the equipment, greatly reducing the production interruption losses caused by equipment downtime, and effectively reducing the company's TCO (total cost of ownership). The main cutting tool is made of high-chromium molybdenum-vanadium special alloy steel. After special processes such as isothermal quenching and deep cryogenic treatment, the Rockwell hardness reaches HRC60-62, with excellent wear resistance and impact toughness, and can stably cope with high-intensity and long-term operations. The auxiliary knife is made of high-quality die forgings and its structure is optimized based on finite element analysis to ensure the dynamic balance and stability of the equipment under complex working conditions. The drive system uses intermediate gear differential transmission technology to accurately match the gear modulus and gear ratio to build a unique differential relationship, so as to achieve efficient and accurate shredding of wood, significantly improving production capacity and processing accuracy.
In terms of performance, the equipment has its advantages. Its feed port is designed based on ergonomics and material flow analysis, and is suitable for a variety of specifications of wood raw materials. Whether it is a log with a diameter of 0.5-2 meters, a board with a thickness of 0.05-0.3 meters, or various types of recycled waste wood, fast feeding and continuous operation can be achieved. The equipment has strong processing capacity, with an hourly production capacity of 10-15 tons, which is 30%-50% higher than the average level of similar equipment. The internal cutter is precisely CNC machined and dynamically balanced, and the layout follows the principle of cutting mechanics, achieving efficient shredding of wood through precise coordination. After laser measurement and screening, the particle size uniformity of the shredded material is more than 95%, and the size deviation is precisely controlled at ±5 mm, which meets the stringent requirements of wood-plastic product production on the particle size distribution of raw materials. In terms of operating stability, the rubber vibration isolators and damping noise reduction devices equipped with the equipment are designed based on vibration theory and acoustic principles, which can stably control the operating noise of the equipment below 70 decibels (A-weighted), fully in line with the strict Class 3 and Class 4 standards in GB 12348-2008 "Environmental Noise Emission Standards for Industrial Enterprises". The pulse bag dust removal system is based on the principles of filtration and adsorption, and has a dust collection efficiency of more than 99.9%, and the emission concentration is less than 10 mg/m3, which is much lower than the national GB 16297-1996 "Comprehensive Emission Standards for Air Pollutants". In terms of energy consumption, through energy-saving technologies such as motor frequency conversion speed regulation and transmission system optimization, the unit energy consumption of the equipment is reduced by about 20% compared with traditional wood shredders. Taking the processing of 1 ton of wood as an example, the energy consumption of traditional equipment is about 50 kWh, while this equipment only requires 40 kWh, which is in line with the current trend of energy conservation and emission reduction in the manufacturing industry, and further reduces the operating costs for enterprises.
For the production of wood-plastic products, the output material of this equipment has significant advantages. From the perspective of material compatibility, wood chips with precise and uniform size can be evenly blended with various thermoplastics (such as PP, PE, PVC, etc.) in a twin-screw extruder, and the material mixing uniformity is improved according to the rheological principle, which effectively enhances the structural strength and dimensional stability of wood-plastic products, and ensures that the mechanical performance indicators of wood-plastic boards, profiles and other products reach or even exceed industry standards in terms of static bending strength, elastic modulus and other mechanical performance indicators, while ensuring that the product appearance is flat and the color is uniform. From the perspective of production process optimization, the output materials of this equipment can directly enter the wood-plastic extrusion molding process after surface treatment, omitting the multiple crushing and screening steps in traditional pretreatment, shortening the production cycle by about 40% based on the lean production concept, and greatly reducing production costs. Looking at the market prospects, as the world's attention to green buildings and sustainable development continues to increase, the market demand for wood-plastic products as new environmentally friendly building materials is increasing year by year. According to the MarketsandMarkets market research report, the global wood-plastic composite material market is expected to grow at a compound annual growth rate of 8.5% from 2025 to 2030. With its excellent performance and cost advantages, this wood shredder from Qingdao Sure Plastic Machinery will effectively seize the market share of front-end equipment for wood-plastic product production, create considerable economic benefits for enterprises, and promote the upgrading of the wood resource recycling industry, helping the industry to develop in a green, intelligent and efficient direction.
As an industry leader, Qingdao Sure Plastic Machinery successfully tested its wood shredder, demonstrating its deep technical accumulation in multidisciplinary fields such as mechanical design, material science, and automatic control, as well as its accurate insight into market demand and innovative response capabilities. The company's head said that in the future, it will rely on the industry-university-research cooperation platform to continue to invest in research and development resources to improve the performance and functions of wood shredders from the perspectives of intelligent control, tool material optimization, and large-scale equipment, and provide one-stop, customized solutions for customers in related industries such as wood-plastic product production, fully promote the efficient recycling of wood resources, and lead the new trend of green development in the industry.
