MJ Series Chancador de Mandíbula

La serie MJ Series Chancador de Mandíbulaes un chancador grueso con una capacidad de producción superior y aplicable para mineral duro y roca chancado, que se adopta con una cámara de chancador simétrica y profunda, una gran apertura de alimentación y un diseño de ángulo de malla optimizado que permite una mayor tasa de operación, una gran relación de chancado y mayor productividad. Con un rendimiento confiable, un menor costo operativo y un mantenimiento conveniente, se puede lograr la mayor capacidad de producción con el menor costo operativo.

Optimized structure:high strength,light weight,simple structrure and strong

MJ series of jaw crushers make full use of CAD and analysis methods of finite element to optimize the crusher.

structure based on long-term experience accumulation. The machine's design emphasizes reducing the equip-

ment weight while ensuring and increasing the strength, increasing reliability, safety and economy. Both fixed and moving jaw plates are box-shaped castings with rippled plate, with the light weight and high strength and stiffness, equipped with a double-sealed sealing lubrication system, which can be safe and reliable;

All welds are avoided from the stress concentration zone, changing the curvature of the component in the stress concentration zone is adopted to increase the strength

Square large feeding,symmetrical deep cavity without dead zone crushing chamber

To improve feeding capacity

MJ series of jaw crushers are equipped with a nearly square large feed opening, deep cavity and with design

of non-dead zone crushing chamber, which can improve the feeding capacity and output.

The top of the moving jaw is equipped with a replaceable thick protection shield for the moving jaw to under- take the feeding impact.

There is no need to install a block plate above the moving jaw of feed opening, and the bulk minerals entering the crusher can fall directly into the movement area of the crushing chamber.

The traditional jaw crushers are adopted with asymmetric crushing chamber design with an effective feeding size smaller than the rated opening. The series of crushers are adopted with symmetrical crushing chamber design, so that the actual opening is equal to the rated opening, which improves the feeding capacity.

The capacity shown in the table only indicates an approximation of the capacity of the crusher. The corresponding condi- tions are open-circuit crushing, dry blasting granite with a bulk density of 1600 kg/m3, the maximum size of which can meet the maximum feed size allowed by the crusher. The lower values in the table apply to the circumstance where the fines of the feeding less than the size of the discharge are rejected, and the higher values apply to the circumstance with contents of fines. The CSS that the crusher can operate normally depends on the feeding granularity distribution, the friability of the material (Wi), the amount of feeding contaminants, the type of jaw plates installed, and the type of its material used.

The Characteristic Curve of Discharge Granularity This curve is a typical granularity characteristic curve of medium crushable rock (Crush- ing Work Index Wi=16). About 75% of the products are less than the CSS. The shape and product of the Granularity Curve is less than the ratio of the CSS, depending on the characteristics of the minerals. For rocks with different friability (Wi between 20-12), normally about 65%-85% of the crushed product is less than the crusher CSS.
