DJM 陶瓷复合圆锥破碎机备件(扎臼壁/破碎壁)技术介绍
DJM ceramic composite cone crusher spare parts (Cone Mantles/Liner) technology introduction
圆锥式破碎机工作时由电动机通过三角带、大带轮、传动轴、小锥齿轮、大锥齿轮带动偏心套旋转,破碎圆锥轴心线在偏心轴套的迫动下做旋转摆动,使得破碎壁表面时而靠近又时而离开轧臼壁的表面,从而使物料在定锥与动锥组成的环形破碎腔内不断地受到冲击、挤压和弯曲而破碎。经过多次挤压、冲击和弯曲后,物料破碎至要求粒度,经下部排出。
圆锥式破碎机目前广泛使用的扎臼壁/破碎壁多是采用高锰钢制造。在物料强烈冲击载荷作用下,及破碎过程中的挤压,碾磨作用,他们易出现宏观断裂失效,同时由于物料与他们之间有相对摩擦切削作用,这些耐磨件的磨损相当严重,针对这一情况,DJM 选用高锰钢为基材的陶瓷复合材料,即扎臼壁/破碎壁的基体采用高锰钢,同时在基体上嵌铸具有高耐磨性的陶瓷随形加强筋,在保持高锰钢原有的加工硬化耐冲击性能的同时提高了高锰钢的耐磨强度,陶瓷复合材料扎臼壁/破碎壁的寿命约为高锰钢扎臼壁/破碎壁的2倍以上。
When Cone crusher works, eccentric sleeve rotates by motor through V-belt, big pulley, drive shaft, a small bevel gear, big bevel gear. crushing cone axis rotates and swing under the pressure of eccentric sleeve, make the cone sometime close to the mantle and sometimes far from it, so that the material in the ring fixed cone and fixed cone crushing cavity composed constantly under attack, squeezing and bending and breaking. After several extrusion, impact and bending, the material is crushed to the required size, and discharged from the lower part.
At present, cone and mantel are mostly made of high Mn steel. They will crack easily under strong impact loads, and the crushing process of extrusion, grinding effect of material. At the same time, the material has a relatively friction between them and the cutting action, so the parts wear out seriously. DJM adopts composites of high-manganese steel substrate and ceramic , namely, the base material of the cone and mantle is high Mn steel, while the cast ceramic matrix embedded with high wear resistance shaped ribs, increase the wear resistance ability while maintaining the original impact resistance of high manganese steel. The life span of ceramic composite cone and mantle is more than 2 times of the ones made of high Mn steel.
