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

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.

 

 

上表中給出的產量只是說明破碎機能力的一個近似值。所對應的條件是開路破碎，物料容重為1600 kg/m3 干燥的爆 破花崗巖，其最大尺寸滿足破碎機允許的最大給料粒度。表中較低的值適用于給料中小于排礦口尺寸的細料被剔除的 情況，較高的值則適用于含有細料的情況。破碎機可以正常運行的最小緊邊排礦口取決于給料的粒度分布、材料的可 碎性(Wi)、給料中污染物的含量、所安裝的顎板類型及其材料種類等。

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.

排料粒度特性曲線 本曲線為中等可碎巖石(破碎功指數Wi=16)的典型粒度特性曲線， 在破碎產品中，約有75%的產品小于緊邊排礦口(CSS)。 粒度曲線的形狀和產品小于破碎機緊邊排礦口(CSS)的比例，取決于 原料的特性。對于可碎性不同的巖石(Wi在20-12之間)，通常其破碎 產品中大約有65%-85%小于破碎機的緊邊排礦口。

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.
