wide range of applications

Tumbler screens are widely used in several industrial fields, and different industries and applications require different specifications and types of tumbler screens. The main ones include:

  1. Plastic recycling: trommel screens are used to separate and screen waste plastics to produce recycled plastic pellets.
  2. Metallurgical industry: used to screen metal ores and mineral sands to extract useful ores and minerals.
  3. Building materials: for separating sand, stone, and gravel to prepare building materials.
  4. Agriculture: In agriculture, trommel screens can be used to screen agricultural products such as pellets, grains, and seeds.
  5. Food processing: In the food industry, tumbler screens are used to screen flour, sugar, cereals, and other food ingredients.

how the Trommel screen works

The waste plastic is loaded into the feed end of the tumbler screen. Once activated, the drum begins to rotate, pushing the material through the screen.

With the continuous rotation of the drum, the material keeps tumbling and the particles smaller than the screen holes pass through the screen holes while the larger ones are retained inside the drum.

In the PET bottle recycling production line, the trommel screen is an important industrial equipment, which is mainly used in the following aspects:

  1. Pre-treatment and sorting: Tumbler screen can sort and screen bottles initially according to their type, color, and size for subsequent processing.
  2. Removal of impurities: Labels, caps, residual liquids, etc. can be effectively removed from PET bottles. This helps to improve the quality and purity of recycled PET pellets.
  3. Screening pellets: After PET bottles are crushed and washed, the tumbler screen is used to screen the pellets to ensure the consistency and quality of the recycled PET pellets.
  4. Material Conveying: Tumbler screens are also commonly used to convey the treated PET bottle pellets to the next process or equipment.
