A hammer mill, hammer forge or hammer works was a workshop in the pre-industrial era that was typically used to manufacture semi-finished, wrought iron products or, sometimes, finished agricultural or mining tools, or military weapons. The feature that gave its name to these workshops was the water-driven trip hammer, or set of hammers, used in the process.

Hammer mill Buschhoff. We recommend to use an Autofilter (Aspiration) when a hammer mill without blower is installed. The fully-automatic Buschhoff autofilter performs the following tasks: It extracts the bruised grain out of the mill, resulting in a very low proportion of fine meal. It causes the bruised grain to cool down after the milling ...

Most grains can be ground in a hammer mill. Grain for human food is ground to a 1mm particle size while animal food is ground to a 3mm particle size. Hammer mills cannot be used for wet milling. Roller mills crush the grains rather than milling them into smaller particles. Roller mills are usually used for animal food. It is important to
