· If the angle of nip is insufficient, it can lead to the feed material riding on top of the rolls while the crusher is attempting to grab and process the material. When this happens, you inhibit material flow and diminish the throughput capacity of the crusher, which may result in material backing up and plugging the feed chutes.
