Solid Waste Trommel Consistency and Reliability

Solid Waste Trommel Consistency and Reliability

Construction of Trommel Screen Machine:

Drum:

The main component of the trommel screen is a cylindrical drum, usually made of steel or stainless steel. 

The drum is mounted horizontally or inclined at an angle. It rotates on its axis driven by a motor or gearbox.

Perforated Screen with a Welded Helical Screw to its inner diameter:

The drum is perforated with holes or slots of customised sizes. The hole diameter and pattern choice depend on 

the desired classification and separation efficiency. The size of the perforations determines the maximum particle 

size that can pass through the screen. The helical Screw of same length as Perforated Screen is welded to an inner 

diameter of the perforated Screen drum.  As the drum rotates in a circular motion, the material inside the drum 

moves forward with Crests of helical screws.

Frame and Support Structure:

The drum is supported by a sturdy frame or chassis, typically made of steel. It provides structural integrity and stability

 to the Trommel Screen.

Support Rollers:

The drum is supported by a series of support rollers or trunnions, which facilitate the smooth rotation of the trommel 

screen. These rollers are often adjustable to maintain proper tension and alignment of the drum.

Drive System:

A motor or gearbox is used to provide rotational motion to the drum. The drive system should be capable of controlling 

the rotation speed and direction of the Trommel Screen machine as needed.

Advantages of Trommel Screen Machine:

Efficiency: The rotating action of the drum helps to agitate and separate particles, ensuring thorough screening and separation.

Versatility: Trommel screens can be used for various materials and applications, making them a versatile screening solution.

Customization: The size of the perforations or mesh, drum dimensions, and inclination angle can be adjusted according

 to the specific requirements of the material being screened.

Low maintenance: Trommel screens have a relatively simple design with few moving parts, making them easy to maintain

 and operate.

Scalping and cleaning: Trommel screens can effectively remove contaminants and perform scalping (removal of oversized 

particles) and cleaning of the material simultaneously.
