Advantages

Enhanced Plant Integrability

Thanks to its compact design, the requirements for floor space and height are minimal, providing greater flexibility in layout planning.
Enhanced Energy Efficiency

The energy-optimized, single-drive design ensures high efficiency to meet modern production requirements.
Enhanced Overall Equipment Effectiveness

The maintenance-friendly belt drive, water cooled rolls and active gap adjustment increase particle stability and performance.

Built to solve. Designed to deliver.

PROBAT GT roll grinders are built to deliver reliable, high-precision performance for industrial coffee grinding. As the cornerstone of an efficient grinding line, they ensure consistent quality and output for standard applications — achieving throughputs of up to 1,800 kg/h in the filter range.

Equipped with two or three pairs of precision-engineered rolls featuring specialized corrugation, the GT progressively grinds coffee from filter to fine grades with exceptional uniformity. Its compact, energy-optimized single-drive design minimizes floor space requirements while maximizing efficiency.

The GT is designed for efficiency, and long-term reliability, featuring a belt drive that simplifies maintenance, water-cooled rolls that ensure optimal temperature control, and an adjustable gap system that maintains consistent particle quality and precise process management. Its newly developed dosing mechanism, which eliminates the need for a slide gate, enables complete regulation of product flow, improving accuracy and lowering operational costs.
