Typical Specifications

Typical throughput

For this class of industrial roller mill, throughput can typically range from 500 kg/h to 1500 kg/h, depending on the desired grind size and product density. Buyers should confirm exact capacity with the seller.

Roller configuration

Petroncini MCR series mills commonly feature multiple sets of chilled cast iron rollers, typically two or three pairs, for progressive grinding. The unit includes two spare rollers.

Power supply

Industrial roller mills of this size commonly require a three-phase electrical supply, typically 400V, 50Hz, with a motor power ranging from 15 kW to 30 kW. Specific requirements should be confirmed with the seller.

Cooling system

Units like the MCR 1000 often incorporate a cooling system to manage heat generated during grinding, which is crucial for preserving product quality, especially for coffee and cocoa. This unit is stated to include a cooling system.

Footprint

For a machine of this capacity, a typical footprint might be around 1.5m x 1.5m x 2.0m (LWH), though exact dimensions will vary. Buyers should request precise measurements from the seller.
