摘　　要：本文介绍一种新研制成功的新型高效破碎机的机械构造、工作原理、性能特点及其在除杂提纯工艺中的使用效果。为了避免物料在破碎腔内出现打滑并保护金刚石单晶在破碎过程中不受到损害,采取了如下措施:其一是将固定破碎板和可动破碎板组成的破碎腔体的形状设计成适合的较小角度,以便减少物料沿破碎板向上滑动的分力,保证物料以近似挤压的方式破碎;其二是在两破碎板上采用特别防滑表面结构,增加工作时的摩擦力,避免出现打滑。结果表明,破碎过程对金刚石单晶保护好,即使将全部合成块物料直接破碎到3毫米以下,金刚石受损部分仅有0.3％。该机特别适用于人造金刚石工业生产中对粉末合成块提纯前的高效预先碎解。The paper introduced the mechanic structure, characteristics, working principle and application result of the newly developed crushing machine. In order to avoid materiel sliding in the breaker and protect the synthetic diamond crystals in the crushed process from being damaged,the following steps are proposed:first,the crush chamber composed of fixed crush plate and movable crush plate be designed into a small angle that is fit for extrusion force break;Adding antisliping structure on the surface of both the two crush plates. The research results show that;during the crushing process diamond crystal are protected well,even if the synthetic cake is crushed to 3 mm and lower. The diamond lose is limited to less than 0.3%. The new high efficiency crushing machine is specially suitable for precrushing the diamond powder cake before purification.
