Circular Swing Screen

1. Product Overview

The Industrial Circular Swing Screen (commonly known as a Tumbler Screener or Tumbler Screening Machine) is a premier, high-precision fine material separation and grading solution designed for processing high-volume bulk powders and granular products. Widely deployed across food processing (such as milk powder, starch, and sugar refining), pharmaceuticals, chemical compounding, plastics, and metallurgy industries, this machine serves as a critical quality guard. By replacing harsh vertical high-frequency shocks with a gentle horizontal rolling displacement, it maximizes material retention time across the wire cloth, enabling high-purity sorting efficiencies that standard round vibratory separators cannot match.

2. Detailed Description

As illustrated in the operational diagram , raw material enters continuously through the centrally positioned top feed inlet . Driven by a high-torque mechanical eccentric drive shaft, the screen frame generates a three-dimensional tumbling motion characterized by radial inclination and tangential velocity. This combination forces bulk material to move in a controlled spiral path from the inner center outward toward the periphery. Smaller fine-sized particles (, represented by the green dots) rapidly filter through the mesh projections, cascading cleanly out via the secondary bottom discharge chute . Concurrently, oversized contaminants and larger grains , represented by the orange dots) slide across the screen cloth surface to be ejected through the primary rim discharge chute . Built entirely from premium polished stainless steel (SUS304 or SUS316L) with high-grade airtight silicone seals, it completely controls atmospheric dust leakage and satisfies the most stringent sanitary regulations.
