A certain amount of impact breaking does take place between hammers and grates, but this is secondary to the work done against the involute plates. On friable material this machine will deliver a medium fine (0.25″ to 3/8″) product with some, or even all, of the grates removed. Capacity of Hammer Mill Crushers

Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.

size a mill. You must know the required annual capacity, whether batch or continuous operation will be required, which upstream and downstream processes will be needed for the mill, and the properties (such as size and shape) of the finished product. Fully characterizing the feed material is essential to identifying the right mill for the job.

Capacity Calculation: The capacity of an impact crusher is determined by the size of the feed material, the rotor speed, the gap between the impact plates, and the material properties. The general formula for calculating the capacity of an impact crusher is as follows: Capacity = (Rotor Diameter x Rotor Width x Rotor Speed) / 600. The …
