Double Toggle Jaw Crushers are preferred for crushing ususually hard, abrasive rocks and other materials like ferroalloys and glass. They differ substantially from other types of crushers. There is no rotary motion in the crushing cycle and all crushing is done by compression of the feed material between two massive jaws plates. The moving jaw compresses the material against the stationary jaw. Jaw plates can be either smooth or corrugated.
