The feed material from the storage hopper is fed into the mouth of the impactor through a vibrating pan feeder whose motors are tuned for a desired output frequency through a variable frequency drive. Belt feeders as in VSI cannot be used for feeding due to the steep feed angle design. The material fed into the crusher first reaches the core of the crushing chamber where it comes in contact with the blow bars. It is very important that the incoming feed material is evenly distributed across the width of the rotor.

The most promising fact about CE Series Impactors is that it will break the material across the naturally occurring fractured zones within the material. Naturally occurring fractured zones are nothing but the fault lines found across the material and it is where the material will break if it is subjected to any naturally occurring forces. So the nature’s process of crushing and shaping has been exploited in impactors.

Once the material has reached the tip of the rotor, it gains momentum by travelling along with the rotor and in that way it’s velocity tends to pick up. The blow bar then smashes the feed material against the apron plates placed exactly opposite to the rotor. The apron plates can be adjusted back and forth in order to adjust the setting of the crusher. When the material hit the hard face of the apron plates, it breaks.
