Grain mill Dolomit series

wheatcornroller

Overview
The Dolomit roller mill series (MDDP and MDDQ) provides a stable, controllable milling stage for grain processing. Available as a four-roller (MDDP) or eight-roller (MDDQ) configuration, it is designed to deliver even feed distribution and accurate gap control for consistent particle size and high throughput.

Key benefits

• Robust and reliable milling: rigid frame and self-contained roller pack ensure mechanical stability; low-wear belt transmission reduces downtime.
• Operator-friendly operation: ergonomic clamping device for precise roller adjustment; clear machine controls and a swing-out feed module for easy access and cleaning.
• Consistent performance: wide inlet and adjustable roller speed distribute product evenly across rollers, supporting uniform grinding and repeatable output.

Highlight features

• Hygienic design: machine geometry and airflow control reduce dust accumulation; partitioned paneling and a 180° swing-out feed module improve access for cleaning and residue removal.
• Safe roller change option: optional roller removal device allows rollers to be supported on metal stands and slid out safely for maintenance.
• Central lubrication: one-point lubrication for bearings to streamline maintenance routines.
• Configurable roll pack: four-roller (MDDP) and eight-roller (MDDQ) layouts to match throughput and grinding fineness requirements.

Applications

• Wheat (including durum)
• Corn / maize
• Rye, barley, spelt
• Oats, buckwheat, millet, sorghum
• Starch raw materials and other grains
