Precision Particle Classification for Efficient Grinding

Our classifiers separate particles by size, helping mineral processing and powder handling plants run more efficiently. Whether used as a standalone unit or integrated into a closed-loop grinding and classification circuit with our ball mills, our classifiers are engineered to deliver a consistent, controllable cut point for your process.

Every classifier we manufacture is engineered around your material characteristics, required fineness, and throughput to deliver consistent and efficient separation performance.

Custom Engineered Configuration

Classifier configuration is finalized based on material characteristics, required fineness, throughput, and process requirements.
