Polygonmachine PSS Series Scalper Screens are engineered for heavy-duty, high-capacity pre-screening and coarse material separation in fixed installations. Designed for mining, quarrying, and recycling operations, these stationary scalper units efficiently handle abrasive materials, ensuring consistent feed quality for downstream crushers and screens.
With their rugged structure, adjustable vibration dynamics, and modular design, the PSS Series guarantees reliability, extended service life, and easy maintenance — even in the harshest working conditions.
