A hammer mill, which is a typical tool for manufacturing woodbased particleboard panels, was found in our previous trial to be effective at breaking down the rice straw. The opening size of perforated metal plates in the hammer mill to control the geometry of straw particles was closely related to the percentage of split rice straws.

During the processing of compound feed for broilers, several changes occur that affect the physical and probably the nutritional properties of pellets, influencing animal performance. The effects of mill type, particle size (PS) and expander conditioning prior to pelleting (E + P) were combined to generate pellets.

A roller mill acts more like a cutting knife. As a roller spins, it creates a shearing effect. Roller mill particle size generally sees lower variance than hammer mills, which results in a more consistent grind. Hammer mills also use different screen sizes to adjust the particle size for either a coarser or finer grain.
