Roller mill Arrakis

in-linehigh-capacityrobust

Overview
Arrakis (MRRK) is a four- and eight-roller mill designed for efficient, high-throughput grinding of a single commodity. The machine is engineered for stable product flow, simplified installation and straightforward operation.

Key benefits

• Fast, simple installation: built on the MDDK footprint for one-to-one replacement; connecting the feed roller to the main roll removes the need for an extra drive and frequency converter, reducing installation scope.
• Consistent high efficiency: load cell sensor provides stable product feed across the grinding surface; intuitive control interface supports operation from multiple devices; latest-generation scrapers improve product hygiene and reduce operator intervention.
• Durable design: robust cast frame with load-carrying structure for vibration absorption; patented grinding-gap adjustment maintains rigidity and stability over long operating periods.

Highlight features
Easy cleaning and maintenance
A quick-release feed module and wide-opening maintenance flap enable fast product evacuation. Automatic feed gate closure prevents trickling between rolls when idle, simplifying cleaning and reducing downtime.

Scraping redefined
Latest-generation synthetic scrapers eliminate dead spots and product build-up. Self-adjusting knife scrapers maintain optimal position for continuous, reliable scraping performance.

With simplicity in mind
Intuitive control interface with optional touchscreen unit provides machine-level operating parameters. Secure remote access enables monitoring and control from mobile devices.

Other features

• Perforated side panels for safe in-line inspection and improved airflow.
• Feeding unit safety grids provide operator protection while allowing sampling access.
• Foreign-object protection to prevent roller damage.

Related automation & software
