DJM 選用高鉻鑄鐵基陶瓷復合鑄造工藝生產襯板，即在高鉻鑄鐵材料表面熔鑄陶瓷顆粒形成陶瓷金屬復合材料層，這層復合層的耐磨性能可達本體材料的3 – 4倍，同時這一復合層的厚度可制成達到原備件厚度的1/3，并可根據原磨損曲線有針對性的制作，利用陶瓷顆粒阻斷了亞表層裂紋向縱深擴展，減小新礦石下滑對表面的沖刷切應力， 減小鑿及碾過程中表面產生鑿削變形的面積。高鉻陶瓷復合鑄造襯板（MMC-Cr-襯板）具有高硬度，高耐磨性。

Ceramic insert Chute liner of SAG Mill

SAG-Feed Chute liner by Ceramic insert casting，that is, the ceramic particles are melted in the high chromium cast iron part of the Chute liner to form the ceramic metal composite material layer. The wear resistance of the composite layer is 2-3 times that of the high chromium material.the High chromium ceramic composite casting Chute liner (MMC- liner) with high hardness and wear resistance
