VOSTOSUN MJ series jaw crushers are mainly applied to coarse crushing in mining and engineering areas and in individual cases they can also be applied to medium crushing, such as production of coarse aggregate. In general, if the single machine capacity is less than 1000t/h, using jaw crusher has more advantages in comprehensive investment, maintain, operation and management than other types of coarse crushing equipment.

MJ series jaw crusher is single toggle jaw crusher. With hollow structure of the moving jaw and stationary jaw, the whole steel castings have high structural strength and rigidity. Welds of frame are positioned in low-stress areas, which ensures excellent performance and durability against shock-loads. Square and bigger effective feed opening, deep symmetrical crushing chamber and optimized nip angle, all the advantages maximize the feed size, reduction and capacity.

Performance Features

- Grease lubrication hoses with a central distribution block makes it easier to grease the bearings. Automatic lubrication system can be connected to the control system for remote alarm indication, which ensures the bearings being protected.
- Bearings are grease-lubricated and the grease filled labyrinth seals protect bearing from dust.
- CSS can be adjusted by traditional shim plates, wedge block and hydraulic auxiliary.
- Jaw plates can be installed to the crushers quickly and easily by using clamping and support bars.
- Sacrificial parts are used to protect the main components of the crusher, so as to reduce the total costs in the life-cycle and increase the uptime of equipment.
- The replaceable support bars and plates are installed to protect jaws from wearing down .
- Large jaw crushers can adopt flexible support, which means they can be installed without anchor bolts.
