GRINDING

Hammer mill

Milling is one of the most important processes in feed production. The objective is to find the optimum particle size by milling the raw material (wheat, corn, barley, etc.).

The new MMR hammer mill model has been a revolution in the sector due to the productivity guarantees it offers, in addition to the new side opening system that facilitates the change of grids.

Features

Performance

High efficiency industrial hammer mills

Our feed hammer mills are designed to provide efficient and high quality grinding. They are equipped with a rotor equipped with hammers that rotate at high speeds, impacting the product to be ground. This provides efficient grinding depending on the final product to be produced: livestock feed, pet food or fish feed.

The mill consists of a steel monobloc body of reinforced construction supported on a base with special anti-vibration dampers for floor mounting.

Design

Simplified maintenance for optimum performance

The Rosal hammer mills are equipped with two-section circular screens, easily interchangeable from the outside, even while the mill is in operation.

The rotor, with reversible clockwise or counterclockwise rotation, ensures maximum utilization of the hammers and sieves.

In addition, easy-access side doors allow simple and quick control for changing hammers, optimizing operational efficiency.

Models

Thinking of all possible grinding fields, Rosal has created different constructive lines. For each mill series, there is the option of installing larger motorizations.
