Before the advent of the cone crusher the usual practice was to make a 2-in. product in two steps consisting of a primary breaker of the jaw or gyratory type followed by a secondary gyratory crusher. If anything smaller were desired, a third stage was added comprising coarse crushing rolls in closed circuit with a screen. The …

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.

Using screens may also decrease the capacity required of one or more crushers, allowing for smaller, less expensive crushers in one or more stages of the circuit. All of the above methods of operation have been proven to reduce or minimize fines generation in coal crushing circuits.
