Working Principle and Mechanism Optimization Design of Jaw Crusher

Jaw crusher is mainly used as a primary and intermediate crusher in mining, construction, infrastructure and other industries. According to the width of the feeding mouth, jaw crusher appears as three types, namely, large one with more than 600mm width of feeding mouth,lime production from limestone equilibrium medium-sized one with 300-600 mm width and small one with less than 300 mm width. Jaw crusher has the features of simple structure, easy production, reliable work, convenient use and maintenance.
Working parts of jaw crusher are two pieces of jaw plates; one is fixed jaw plate (fixed jaw) which is vertically (or slightly extroversive on the upper end) fixed on the front wall of the machine, and the other is moveable jaw plate (movable jaw) which is tilted and forms the (big-end up) crushing chamber with the fixed jaw. The movable jaw crusher does periodic and reciprocating motion facing the fixed jaw and moves away from and toward it over and over again. When it moves away,limestone crusher 50 tph top brand materials go into the crushing cavity, and finished products get out from the bottom; when it moves toward the fixed jaw, materials between the two pieces of jaw plates will be crushed by the forces of impacting, bending and splitting.
According to the different swinging ways of its movable jaw plate, jaw crusher can be divided into three types,limestone crushing for cfb power plant namely, simple pendulum type jaw crusher, complex pendulum jaw crusher (compound pendulum jaw crusher) and integrated pendulum jaw crusher.
The technology levels of domestic jaw crusher manufacturers are greatly different. The products of only several manufacturers almost approach world advanced level, while most manufacturers are far from that level. The frame of jaw crusher takes a large proportion of the whole machine (casting frame 50%, welding frame 30%). The frame of foreign jaw crusher is welded and so is the moving jaw. Adopting the welded frame is the development...
