Preface: The shaftless Trommel Screen is a screening device widely used in industrial production lines. It can perform fine screening and separate different materials in many different materials. As an efficient and highly automated screening device, the shaftless Trommel Screen plays an important role in modern industrial production. In this article, we will explore in depth the working principle, advantages, precautions, usage scenarios and other aspects of the shaftless Trommel Screen.

A. Working principle of the shaftless Trommel Screen

The shaftless Trommel Screen consists of a screen drum, a flap, a motor and other parts. Its working principle is to evenly add the screened material from the material inlet into the screen drum, and then continuously rotate the screen drum through the screen to finally classify and separate the material. During the entire screening process, materials of different particle sizes will be separated into different tanks or pipes according to their size and shape.

B. Advantages of the shaftless Trommel Screen

The shaftless Trommel Screen is a commonly used screening equipment and is widely used in many industries. Its advantages are mainly reflected in the following aspects:

1. Higher reliability: The shaftless Trommel Screen has no central axis, so there is no risk of central axis breakage, which greatly improves the stability and reliability of the equipment.

2. High screening efficiency: The screen design of the shaftless Trommel Screen is flexible, and the size and shape of the screen holes can be adjusted according to different screening requirements, thereby improving the screening efficiency. The use of special screens also further improves the screening effect. The shaftless Trommel Screen uses a high-speed rotating screen drum, which can quickly screen the material and improve work efficiency. At the same time, the screen aperture of the shaftless Trommel Screen is small, which can efficiently screen tiny particles.

3. High degree of automation: The shaftless Trommel Screen has a high degree of automation, and can be automatically controlled through the control system, effectively improving the production efficiency and quality management of the production line.

4. Easy maintenance: Since there is no central axis, the replacement and maintenance of the screen become more convenient and quick, reducing maintenance time and cost. At the same time, its internal Trommel Screen accessories are designed separately, saving raw materials, larger screening space, and more convenient maintenance. Since the shaftless Trommel Screen is a modular structure, maintenance and replacement of parts are very convenient and quick.

5. Low noise and vibration: Due to the stable rotation speed of the shaftless Trommel Screen and its scientific structural design, it has low noise and vibration during operation, and will not cause any impact on the health of production operators.

6. Reduced energy consumption: How much lower the energy consumption of a shaftless Trommel Screen is compared to a shafted Trommel Screen depends on many factors, including the model of the equipment, the type and amount of material being processed, and the operating conditions. According to relevant information, the motor power of a shaftless Trommel Screen is usually smaller, which is one-half to one-third of that of other screen types. This means that when processing the same amount of material, the operation time of a shaftless Trommel Screen is only one-half of that of other screen types, so the energy consumption is low. Specifically, if the energy consumption of a shafted Trommel Screen is set to 100%, the energy consumption of a shaftless Trommel Screen may be between 33% and 50%. This shows that the shaftless Trommel Screen has a significant advantage in energy consumption and can save users a lot of energy consumption. 7. Better adaptability: The shaftless Trommel Screen can adapt to a wider range of material types and more complex screening environments. It is particularly suitable for screening materials with high viscosity and easy clogging, such as construction waste, domestic waste, wet ore, etc. 8. Stronger anti-clogging ability: The screen tensioning method and structural design of the shaftless Trommel Screen make it have stronger anti-clogging ability when processing materials with high water content and easy to agglomerate. The material rolls in the Trommel Screen, and the material stuck on the screen is easily discharged without clogging the screen holes.

9. Longer service life: The structural characteristics of the shaftless Trommel Screen make the wear of the screen and the drum more uniform, thereby extending the service life of the screen and the drum.

10. Better energy-saving effect: The structure of the shaftless Trommel Screen is simplified, which reduces mechanical friction and energy loss, so it usually has better energy-saving effect during operation.

11. More flexible installation method: The shaftless Trommel Screen can be designed into a variety of installation methods, such as horizontal installation, inclined installation, etc., to adapt to different space and process requirements.

12. Superior environmental protection performance: The drum of the shaftless Trommel Screen adopts a fully sealed structure, with low dust, less pollution and low noise, which meets the environmental protection requirements of modern industry.

The shaftless Trommel Screen has been widely used in mining, building materials, chemical industry, metallurgy and other industries with its many advantages, and has been widely praised by users.
