Shaftless Trommel Screen VS Shafted Trommel Screen

Compared with shafted drum screens, shaftless drum screens have obvious advantages in the sorting process, especially when screening urban domestic waste, construction waste, stale waste, and large stones. However, due to the limitation of the intermediate shaft, shafted drum screens have restrictions on the screening materials.

The shaftless drum screen is driven by an external gear ring, with a large internal space, small obstructions, and easy maintenance. It is also equipped with a self-vibrating device and a high-pressure water pipe to enhance the self-cleaning function. The shaftless drum screen reduces the problem of screen hole clogging, improves screening output, and reliability. It has good sealing and is easy to disassemble and assemble. The machine body is equipped with a quick-opening maintenance door for easy maintenance.

The advantages of the shaftless drum screen

1. High screening efficiency

The shaftless drum screen can be equipped with a combing mechanism, which effectively improves the screening efficiency of the equipment.

2. Large screening volume

Under the same size, the circular area is larger than other shapes, and the effective screening area is large, so that the material can fully contact the screen, and the screening volume per unit time is large. Due to its simple structure, convenient layout, novel technology, and maturity, it is easy to scale up.

3. Low energy consumption

The motor power is small, which is half to one-third of other screening types. Processing the same amount of material, the running time is only half of other screening types, and the energy consumption is low.

4. Good working environment

The entire screen drum can be sealed with a sealed isolation cover to completely remove dust flying and block splashing during the screening cycle, avoiding pollution to the working environment. When the equipment is in operation, the noise generated by the material and the rotating screen is completely isolated by the sealed dust cover, so that the noise cannot be transmitted to the outside of the equipment, thereby reducing the equipment noise.

5. Long service life and low maintenance

The rotary screen is composed of multiple ring nets, and the total screen area is much larger than other screen areas. The screen efficiency is high, the equipment operation time is short, the service life is long, there are few wearing parts, and the maintenance is small. There are equipment observation windows on both sides of the equipment sealing dust cover. The staff can observe the operation of the equipment at any time during work. There are maintenance quick-opening doors at the end of the sealing cover and the side of the cleaning machine mechanism. It is very convenient for regular maintenance of the equipment and does not affect the normal operation of the equipment.

6. Wide range of applications

The shaftless drum screen is widely used in domestic waste sorting technology, and waste classification management is carried out according to particle size. The sorting accuracy is high and the equipment operation is reliable. In addition, it is also suitable for product classification in mining, building materials, transportation, energy, chemical and other industries.
