Pulverizer Hammers

Hammer pulverizers have fixed or swinging steel hammers used for coarse crushing. They are capable of considerable fine milling as well. The hammers may be in vertical or horizontal rotor configuration.

The material here is forced against a rotating hammer and then against a break plate. The material is then passed over discharge sieve where the finer material is passed out and the larger particles go back to the hammering cycle. The particles are impacted throughout the process by the hammer or the sides till the time it can pass through the sieve.

The drawbacks of a hammer pulverizer is that it cannot handle very large particles and the output is uneven. The hammers tend to wear out due to material abrasiveness.
