Trommel Screen Separator

Introduction to Trommel Screen Separator

As a device that relies on mechanical rotation to achieve material classification, the Trommel Screen Separator has become an indispensable pretreatment equipment in the metal recycling process due to its efficient separation ability for materials of different particle sizes. It provides materials with uniform particle sizes for subsequent crushing, sorting and other links, helping the metal recycling industry to achieve refined and efficient production. ​

I. Principle

The core working principle of the Trommel Screen Separator is to use the rotation of the drum and the difference in the aperture of the screen to achieve material classification. The main body of the equipment is an inclined cylindrical drum, and the inside of the drum is equipped with screens of different apertures (single or multiple layers of screens can be set according to needs, and the aperture of each layer of screen gradually increases from the inside to the outside). When the scrap metal material to be processed enters the drum through the feed port, as the drum rotates slowly, the material is continuously lifted and dropped in the drum. ​
In this process, materials with a particle size smaller than the aperture of the screen will fall into the corresponding collection hopper through the pores of the screen to complete the initial screening; while materials with a particle size larger than the aperture of the screen will continue to move to the end of the drum under the rotation of the drum, and finally be discharged from the discharge port. For a Trommel Screen Separator with multiple layers of screens, materials of different particle sizes will pass through the corresponding mesh layers and fall into different aggregate areas, realizing one-time classification of materials of various particle sizes. By adjusting the rotation speed, inclination angle and mesh aperture of the drum, the screening efficiency and classification accuracy of the material can be flexibly controlled to meet the processing requirements of different materials. ​

II. Advantages​
1. Wear-resistant and impact-resistant to extend service life: Metal recycling materials often contain hard metal blocks, sharp metal edges, etc. The drum and screen of the Trommel Screen Separator are made of high-strength wear-resistant materials (such as high manganese steel and wear-resistant alloy steel), which have strong impact and wear resistance, can withstand long-term friction and collision of materials, effectively extend the service life of the equipment, and reduce the cost of frequent replacement of parts. ​
2. Convenient and flexible screen replacement: Different metal recycling scenarios have different requirements for material classification particle size. The screen of the Trommel Screen Separator adopts a modular design, and the replacement process is simple and convenient. Operators can quickly replace screens of different apertures according to material characteristics and processing requirements, and flexibly adapt to various screening tasks from coarse screening to fine screening to meet diverse production needs.​
3. Stable operation, low noise and reduced interference: The Trommel Screen Separator is driven by a reduction motor, and the operation process is stable and low noise. A shock absorber is usually installed at the bottom of the equipment, which can effectively reduce the vibration generated during the operation of the equipment and reduce the interference to the surrounding environment and other equipment. It is suitable for use in industrial places with certain restrictions on noise and vibration. ​
4. Seamless connection with the production line: The Trommel Screen Separator can be easily integrated into the metal recycling automation production line, and seamlessly connect with the front-end material conveying equipment and the back-end crushing and sorting equipment. Through the coordination of the control system, continuous feeding, automatic screening, and graded discharge of materials can be achieved, forming a coherent process of "feeding-screening-grading processing" to improve the automation of the production line. ​

III. Value ​
1. Protect subsequent equipment and reduce maintenance costs: Through the graded screening of materials, the Trommel Screen Separator can effectively prevent large and hard materials from directly entering crushers, sorters and other equipment, reduce the wear, failures and repair times of these equipment due to material incompatibility, reduce the maintenance cost and downtime of equipment, and extend the service life of equipment.​
2. Improve overall production efficiency: The material size after screening by the Trommel Screen Separator is uniform, which reduces the downtime of subsequent equipment due to material blockage, jamming and other problems, so that crushing, sorting and other equipment can continue to operate efficiently, thereby improving the processing capacity and production efficiency of the entire metal recycling production line. ​
3. Improve resource recycling rate: The Trommel Screen Separator can not only remove fine impurities, but also recycle and process metal materials of different particle sizes separately. Small metal debris can directly enter the sorting link, and large pieces of metal waste are processed after crushing, avoiding the omission or waste of some metal resources due to material mixing, and improving the overall recycling rate of metal resources. ​
4. Help refine production management: The grading function of the Trommel Screen Separator makes the material management in the metal recycling process more refined. By separately processing materials of different particle sizes, enterprises can formulate more reasonable production processes according to the characteristics of materials, optimize resource allocation, reduce production energy consumption, and realize refined and energy-saving production management mode.​

As the metal recycling industry develops towards automation and refinement, the Trommel Screen Separator has become a key equipment in the pre-treatment link of metal recycling with its reliable grading and screening capabilities, product advantages for the industry, and optimization of the production process, laying a solid foundation for the efficient, stable and sustainable development of the metal recycling industry. ​
