Rotary Trommel

How Rotary Trommels Work

Rotary trommels are incredibly useful for the sorting of materials. The tumbling action, which takes place within the rotary trommel, allows for the sizing and separation of municipal solid waste and resource recovery. As the drum within the Rotary Trommel turns, the material begins to tumble onto other material at the bottom of the drum. This action helps to break down the materials into smaller portions, as well as separate different types of materials. As the material continues to tumble within the rotary trommel, smaller size pieces filter through holes in the screen, while larger material continues to be further sorted and processed.

General Kinematics Rotary Trommels

GK Rotary Trommels are designed to efficiently separate and size recyclable material that is prone to sticking or jamming in other secondary separation technology. Heavy-duty drive systems and trommel bodies are easy to clean and easy to maintain. Super-duty trommel designs impart greater impact force to the product and are optimized for materials such as glass recovery and shingle processing. For more information on rotary trommels, contact a GK Recycling Technology expert.

Features:

• Material infeed can be through either a bag opener for municipal waste or to a bypass feeder for C&D and other non-bagged materials.
• Separation is achieved using GK’s FINGER-SCREEN™ for initial separation, a vibratory fines screen, and through the use of GK’s DE-STONER® Air Classifier.
• Ferrous separation is also available on the A line, B line, or both.
