The particle size produced by a hammer mill can vary depending on several factors such as the design of the mill, the speed, the screen size, and the nature of the material being processed.

Typically, hammer mills are used to produce a wide range of particle sizes, from coarse to fine. They are often used in industries such as agriculture, food processing, and pharmaceuticals for grinding materials into smaller particles.

The particle size produced by a hammer mill can range from hundreds of microns to a few millimeters. Some hammer mills are capable of producing very fine particles, while others are better suited for coarse grinding.

To determine the exact particle size produced by a specific hammer mill, it would be necessary to refer to the manufacturer’s specifications or conduct experiments under controlled conditions.
