The design of the crushing cavity openings directly affects performance in hammer crushers and jaw crushers.
Jaw crushers feature a wedged, tapered cavity opening (wide at the top, narrow at the bottom). With a deep, large opening, it relies on extrusion between moving and fixed jaws, ideal for coarse crushing of hard ores and rocks. Discharge size is adjusted via the lower outlet.
Hammer crushers have an open/semi-open cylindrical cavity opening with greater horizontal space. It uses high-speed hammer impact instead of extrusion, offering better material flow. Suited for medium-fine crushing of softer materials, with particle size controlled by hammers and screens.
In short: jaw crusher cavity openings focus on large-block extrusion and coarse crushing, while hammer crusher cavity openings emphasize impact crushing and high throughput.
