Ideally, material to be crushed would be fed in a controlled fashion over the entire width of the Hammermill rotor by some type of Feeder (e.g. a belt conveyor). This method allows for the most consistent operation, crushed product, and wear life of components. In situations where a client may not wish to incorporate a feed conveyor, Sample Hammermills can be slug fed, but this has limitations with respect to the amount of material that can be presented to the crusher in one slug and usually requires additional motor power to prevent the crusher rotor from slowing. The best way to determine the right feed operation is to check with the equipment supplier to determine the best configuration and plan for operating a Sampling Hammermill in your application.
