Shaftless trommel screen is a new type of screening equipment, the main feature is that there is no central shaft, and it is composed of motor, reducer, frame, supporting roller, drum device, etc. Because of its advantages of high efficiency, energy saving, environmental protection, etc., this kind of screening equipment is widely used in various material screening and screening operations, especially in decoration waste treatment projects.
There are three main transmission modes of shaftless trommel screens: chain drive, gear drive and idler drive. In the renovation garbage disposal project, the working principle of the shaftless trommel screen is as follows:
First of all, the decoration waste is first conveyed to the feed port of the trommel screen. The motor drives the drum unit to rotate through the reducer. Due to the inclination angle and rotation of the drum device, the material is discharged through the screen of the outer ring of the drum, and the unqualified material is discharged through the end of the drum.Shaftless trommel screens have significant advantages in renovation waste treatment projects. First of all, its design without a central shaft makes the screening process smoother and reduces the possibility of material clogging. Secondly, the shaftless trommel screen has almost no restrictions on the materials screened, especially suitable for processing materials that are difficult to screen such as ribbon and strong winding. In addition, the shaftless trommel screen has a variety of transmission modes, and the appropriate transmission mode can be selected according to specific needs.In the screening process, the screen of the shaftless trommel screen can be replaced as needed to adapt to the screening of materials of different specifications.
The screened material can be further processed as required, e.g. **, reused or transported to a designated location.
However, there are also a few things to keep in mind when running a shaftless trommel screen. First of all, it should be ensured that there is no loud abnormal noise during the full load test operation, and the temperature of the rolling bearing does not exceed 70°C. Secondly, during the load test run, the material should be loaded evenly to avoid excessive knocking sound. In addition, the maintenance and maintenance of the equipment is also very important, and the operation status of the equipment should be checked regularly, such as whether the solid parts are reliable, whether the rotating parts are flexible, etc., and the debris in the equipment should be removed in time.
In general, shaftless trommel screens play a key role in decoration waste treatment projects, and its characteristics of high efficiency, energy saving and environmental protection make decoration waste can be effectively treated and recycled.
