The material must possess heat resistance properties since it will …
Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.
