Pre-breaking or crushing is a commonly used method within the pharmaceutical, nutraceutical and allied industries. The Hanningfield Pharmaceutical Crusher (Pre-Breaker) offers fast and effective breaking of materials for initial sizing, prior to size reduction milling. Hanningfield's Crusher can also be used as a stand-alone machine if the fine particle size is not an essential requirement.
Maximum particle size should not exceed 80% of the gape. For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm. In actual operations, the crusher will occasionally accept particles up to the gape size, as long as bridging does not occur. The overhead eccentric is an integral part of the moving plate, which
