Roller Screen

1. Product Overview

The Industrial Roller Screen (also known as a Roller Grizzly or Disc Screen) is a highly efficient, non-vibrating classification solution engineered for the heavy-duty sizing and scalping of moist, cohesive, or oversized bulk solids. Widely deployed in coal preparation plants, power generation facilities, mining operations, and cement processing lines, this equipment regulates raw material flows before primary or secondary crushing stages. By utilizing a series of continuously rotating shafts, it effortlessly handles materials like wet coal, clay-laden iron ore, and limestone that would quickly blind or fail on traditional vibratory screening equipment.

2. Detailed Description

This equipment consists of a robust, sloped rectangular housing containing multiple parallel roller shafts arranged in a stepped configuration. Each shaft is outfitted with precisely spaced discs or polygonal profiles and driven by an individual side-mounted motor and reducer assembly. As the raw material enters from the high-end inlet, the forward-rotating rollers fluidize the material bed, cascading the bulk load downhill. Smaller fine particles fall cleanly through the constant geometric gaps between adjacent rollers, while oversized rocks, frozen coal lumps, or debris are driven forward and smoothly discharged out of the end. This design provides an inherently self-cleaning mechanism, as the rotational shearing motion breaks material bonds and prevents packing.
