GRINDING

Hammer mill

Grinding 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 Rosal hammer mill model has revolutionized the industry due to the productivity guarantees it offers, as well as its innovative side opening system that makes grid changes easier.

Features

Rosal hammer mills for grinding cereals and flours for the production of compound animal feeds.

Performance

High-efficiency industrial hammer mills

Our 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 hammer 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.

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.
