    Hammer Mill components operating principles types uses

    Disadvantages of Hammer Mill. Not recommended for the fine grinding of very hard and abrasive material due to excessive wear. Not suitable for low-melting sticky or plastic-like material due to heat generation in the mill head as a result of mill fouling. The mill may be choked if the feed rate is not controlled leading to damage.
