Hammermill Crushers | McLanahan
Hammermill Crushers often require a 1:1 ratio comparing horsepower to tph throughput. That ratio can grow to 3:1 for many applications, and even 5:1 when fine-grinding is required. Direct drive via a flexible coupling is often the choice, when and if a motor of the same rpm can be locally sourced and serviced.

is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills.
