DJM 陶瓷復合圓錐破碎機備件(扎臼壁/破碎壁)技術介紹

DJM ceramic composite cone crusher spare parts (Cone Mantles/Liner) technology introduction

圓錐式破碎機工作時由電動機通過三角帶、大帶輪、傳動軸、小錐齒輪、大錐齒輪帶動偏心套旋轉,破碎圓錐軸心線在偏心軸套的迫動下做旋轉擺動,使得破碎壁表面時而靠近又時而離開軋臼壁的表面,從而使物料在定錐與動錐組成的環形破碎腔內不斷地受到沖擊、擠壓和彎曲而破碎。經過多次擠壓、沖擊和彎曲后,物料破碎至要求粒度,經下部排出。

圓錐式破碎機目前廣泛使用的扎臼壁/破碎壁多是采用高錳鋼制造。在物料強烈沖擊載荷作用下,及破碎過程中的擠壓,碾磨作用,他們易出現宏觀斷裂失效,同時由于物料與他們之間有相對摩擦切削作用,這些耐磨件的磨損相當嚴重,針對這一情況,DJM 選用高錳鋼為基材的陶瓷復合材料,即扎臼壁/破碎壁的基體采用高錳鋼,同時在基體上嵌鑄具有高耐磨性的陶瓷隨形加強筋,在保持高錳鋼原有的加工硬化耐沖擊性能的同時提高了高錳鋼的耐磨強度,陶瓷復合材料扎臼壁/破碎壁的壽命約為高錳鋼扎臼壁/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.

Product include:

High Mn Steel:  Mn18Cr2-Re+Ti  Mn18Cr2  Mn13  Mn13Cr2

High Mn Steel + inlay of ZTA Ceramic particles
