Jaw crusher of eccentric shaft bearing usually adopts concentration circulation lubrication. Heart axis and the thrust of the support of face plate general use by manual oil gun grease to oil. Move the angular jaw is very small, the heart of jaw crusher between shaft and bush lubrication, often in difficulties between the bottom bearing some axial oil groove open, open a ring to the oil among the connected with oil pump, and then forced into dry butter lubrication.

          Jaw crusher product, has broken than big, products of granularity, simple structure, reliable operation, easy maintenance, low operating cost, etc. Jaw crusher is widely used in mining, metallurgical industry, building material, highway, railway, water conservancy and chemical industries in many industries, the broken compressive strength of less than 320 million mpa of various materials. PE, PEX series jaw crusher is complex swing type used in crushing equipment, metallurgy, mining, construction, transportation, cement, and other departments, as a crushing, crushed in the compressive strength in 300 Mpa the following all kinds of ores or rock with. With simple reasonable structure, high output, broken than big, long service life, finished product gear plate of granularity, low power consumption, maintenance convenience etc, is the present domestic most advanced model.

          This series crusher way as the working principle is: motor drive belt and pulley, through the eccentric shaft to move up and down movement, when moving the jaws jaw rise cubits board with move between the jaw Angle change, so as to promote dynamic jaw plate to fixed jaw plate close, at the same time the material being crushed or broken, to split the purpose of broken; When moving downward jaw, cubits plate and move between the jaw Angle, move in smaller jaw plate lever and spring, the function of fixed jaw plate, this time the left has broken material crushing cavity from your mouth eduction. With the motor turns continuously and broken motor jaw broken and excretion for periodic pressure material, realize batch production.
