FAQ

It meters product evenly into the hammer or roller mill and removes metal and stones, protecting the mill and stabilising performance.

By a frequency-controlled motor reducer driving the feed roller, allowing precise adjustment to the mill’s load.

A permanent magnet with automatic cleaning extracts iron; a stone catcher removes heavy contaminants. Debris is collected in a tray.

Yes. An optional multiple dosing screw feeder keeps poor-flow or high-fat materials moving evenly to the mill.

Typical capacity is up to 60 t/h with feed widths up to 1,250 mm; project-specific sizing is selected during engineering.
