The width of the crusher must also be considered when taking into account the feed size. Selecting a crusher that is too narrow compared to the size of the incoming feed can result in the bridging of the feed material across the crusher opening. When this occurs, once again, throughput capacity is diminished and plugging of the chutes can occur.
