The invention discloses a high-wear-resistance easy-to-process ceramic chopper and a preparation method thereof, and relates to the technical field of ceramic choppers. The ceramic chopper comprises a chopper body, a welding nozzle and a wire passing through hole, wherein the wire passing through hole extends to an inner chamfer of the welding nozzle in the longitudinal axis direction of the chopper body; the chopper body is composed of a first sintering body and a second sintering body, and the first sintering body surrounds the second sintering body. The preparation method of the ceramic chopper comprises the following steps: uniformly mixing a binder with first sintered body ceramic powder and second sintered body ceramic powder to obtain a first sintered body feed and a second sintered body feed; and then forming, sintering and grinding the first sintering body feed and the second sintering body feed to obtain the ceramic chopper. By the adoption of the method, the ceramic chopper with the first sintering body high in hardness and abrasion resistance and the second sintering body high in toughness and easy to machine can be obtained, the service life of the ceramic chopper is greatly prolonged, and the production cost is reduced.
本发明公开了一种高耐磨易加工的陶瓷劈刀及其制备方法，涉及陶瓷劈刀的技术领域。本发明所述陶瓷劈刀包括劈刀本体、焊嘴及过线通孔，过线通孔沿劈刀本体的纵轴方向延伸至焊嘴的内倒角处；劈刀本体由第一烧结体和第二烧结体组成，第一烧结体包围第二烧结体设置。本发明所述陶瓷劈刀的制备方法如下：将粘结剂分别与第一烧结体陶瓷粉、第二烧结体陶瓷粉混合均匀，得到第一烧结体喂料、第二烧结体喂料；然后将第一烧结体喂料和第二烧结体喂料进行成型、烧结、研磨加工，获得陶瓷劈刀。通过采用本发明的方法可得到第一烧结体具有高硬度及高耐磨性、第二烧结体具有高韧性易于加工的陶瓷劈刀，大大提高了陶瓷劈刀的使用寿命，且降低了生产成本。
