Multi-Deck Grading Sieve for EPDM Granule Classification
.
The Challenge: Precision Sizing for Recycled EPDM Flooring
An EPDM floor construction material manufacturer required a high-efficiency solution for grading ground rubber. The process required the precise removal of “oversize” contaminants (>5mm) and fine “dust” (<1mm) to ensure a consistent 0.5–5mm grain size for the final product.

The Solution: 2-Deck Linear Vibrating Screener
We supplied a heavy-duty 2-deck vibrating sieve specifically engineered for high-accuracy classification. Unlike standard vibratory units, this system utilizes an out-of-balance motor to drive the separation process.

- Horizontal Reciprocating Motion: The motor creates a specific linear movement that keeps material in contact with the mesh longer, resulting in more effective de-dusting and scalping.
- Triple Fraction Separation: The two-deck configuration allows the plant to separate the EPDM into three distinct streams—overs, unders, and the primary product—in a single pass.

The Result: Improved Product Quality and Throughput
By switching to a motor-driven linear screen, the client achieved superior separation compared to traditional vibrating sifters. The more aggressive horizontal action prevents “blinding” (mesh clogging), ensuring continuous production and a cleaner final granule for flooring applications.
