Application: Persisetent EK Series Impactor is a horizontal shaft, slow speed, non-reversible, fixed blade impact crusher. Because of its unique design configuration it is ideally suitable for fluidized Bed Boiler requiring coal size below 6mm with limited quantity of fines which is not possible to achieve from conventional Impactor or Ring Granulator. These impact crushers are also employed for sponge iron and washery application. Operating Principle: Feed material entering into feed end at the top gets shattered by the impact blows from rotating blow bars against the grinding wall. At the lower portion of the crushing chamber it is subjected to shearing and attrition to some extent producing finer product size with limited quantity of fines, thus, overcoming the limitation of a swing hammer mill and conventional impactor. Uniform feeding across the entire width at controlled rate by suitable feeding system is essential to ensure uniform wearing pattern and consistency of product granulometry.
