Master Magnets can supply trommel screens for size separation within the recycling industry. The waste is usually fed into the trommel at a high throughput rate. The trommel then rotates at a slow speed with small particles of waste escaping out of the trommel through the grid. The larger sized waste continues to pass through the trommel with fines removed. This then separates the waste into specified sizes. These are most commonly used in MRF plants where size separation is an important process to profit from waste. For example if demolition waste is passed through a trommel screen soil can be reclaimed making it available for re-use enabling customers to profit from waste.
