In heavy industrial applications such as waste-to-energy plants, metallurgical slag handling, and construction material processing, efficient pre-crushing screening of bottom slag is a critical step. Bottom slag—a coarse, irregular, and abrasive byproduct—requires rugged equipment that can withstand impact, separate oversized material, and ensure consistent feeding to downstream crushers. The Bar Screen, also known as a bar-type vibrating feeder or grizzly screen, is specifically engineered for such demanding conditions.
Application: Bottom Slag Screening and Feeding
Bottom slag is often composed of a mixture of hard, uneven particles with varying sizes and densities. Feeding such materials directly into a crusher without proper separation or sizing can lead to severe wear, reduced efficiency, and even equipment failure. The Bar Screen is designed to solve these issues by performing two key functions: screening and feeding.
Equipped with robust bar-type decks and powered by a vibration motor, the Bar Screen uniformly feeds large chunks of material into crushers while simultaneously screening out fine material, dust, and debris. This dual-action approach not only improves crusher efficiency but also protects it from excessive wear and tear.
