Particle shape is the quality parameter most affected by variations in the crushing process. The maximal product particle size is highly dependant on the setting of the crusher, so for comparison of particle shape for full gradations, the size range analysed should be related to crusher setting (CSS). –
Crushing is a basic but important process widely encountered in the mineral industry. To adapt to different working conditions, many types of crushers have been designed, such as impact crushers [[1], [2], [3]], cone crushers [4, 5], and jaw crushers [[6], [7], [8]].Among them, the impact crusher, in which the feed materials break due to the strong impact with mechanical …
The use of vertical shaft impact (VSI) crushers is one possible solution, since VSI crushers can create particles with a good aspect ratio and smooth surfaces for use in different applications ...
particle breakage, DEM has been used to obtain particle collision energies. Several different product size distribution models have also been used to better predict the behavior of different crushers and feed sizes. To facilitate this, a framework to improve sites has been developed.

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.
