for mining operations worldwide. AlpineGrind AG engineers mineral processing equipment that stays productive where the conditions are at their hardest.

A note from the CEO
“Working at many different mine sites made me aware, that there is no stirred mill technology available living up to today’s requirements of safe and profitable mining. The Migmill technology fills this gap being the most efficient, best maintainable and operatable regrind mill at lowest cost on the market.”

02What we do

PERFORMANCE BY DESIGN.

From first concept to lifecycle support, we focus on the details that keep a plant moving.

As the owner and developer of MIGmill technology, we design and manufacture high-performance vertical stirred mills and original wear and spare parts for ultra-fine to coarse grinding applications in mineral processing. MIGmill represents our latest generation of advanced stirred mill technology, combining a highly efficient grinding principle with excellent operability and maintainability, and process performance. This enables reliable particle size distribution, optimized recovery rates, and consistently high performance across a wide range of operating conditions.

The MIGmill design incorporates optimized wear components that significantly reduce wear on both grinding media and mill components. This contributes to lower energy consumption, reduced wear-related costs, and minimized maintenance requirements, providing clear advantages in both CAPEX and OPEX. High grinding efficiency, improved availability, and extended service intervals translate directly into a lower total cost of ownership for operators.

Our scope of supply covers complete MIGmill equipment for new installations, as well as original wear and spare parts for existing MIGmill operations. As the technology owner and manufacturer, we provide direct technical expertise throughout the entire lifecycle of the equipment. From engineering and equipment supply to spare parts and lifecycle support, our objective is to minimize downtime, simplify procurement, and ensure long-term operational reliability and sustained performance of your grinding assets.
