In Blake Jaw crusher feed is admitted between the two jaws, set to form a V open at the top. One jaw, the fixed or anvil jaw is nearly vertical and does not move;

 — Jaw crushers are mainly used in operations where the volumes involved do not justify a gyratory crusher. The throughput of a jaw crusher ranges between 30 and 1200 tph (Wills and Napier-Munn, 2015). Jaw crushers have been modelled previously; in 1953, Gauldie conducted a performance study of the jaw crusher, including a capacity model …
