The series of jaw crusher has the characteristics of large breaking ratio, uniform product size, simple structure, reliable operation, easy maintenance, low operating costs and so on. Jaw crusher s are widely used in mining, melting, building materials, roads, railways, water conservancy, chemical industry and many other sections to crush all kinds of materials of which the compressive strength is less than 320 Mpa.
Uses and servicable range:
1. The series of jaw crusher s are mainly used for middle crushing and fine crushing of mid-hard ore and rocks in the sections of metallurgy, mining, chemical industry, cement, construction, ceramics together with refractories.
2.These crusher s are most suitable to crush all kinds of soft and hard ore whose compressive strength is not higher than 300 Mpa. The maximum lumpiness of materials to be crushed should follow the technical data chart.
Operating principle:
The motor drives the belt wheel, and makes movable jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw is down, the angle between the fixed jaw and movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the function of drawbar and spring. And then the crushed materials are discharged from the lower outlet of the crushing cavity.
