我厂的反击式破碎机打击板大多是采用铸铁件,价格便宜,但是耐磨损性能较差,破碎时遇到较硬物料容易断裂。据统计,每付打击板平均仅用5天。现经改进采用低碳钢加工打击板,然后在其打击板面上堆焊硬质合金,取得了较好的经济效果,使用寿命延长到40天。采用的是四川省自贡硬 The impact crusher of our factory’s counterattack crusher is mostly made of cast iron. It is cheap, but its wear resistance is poor. When it is broken, it encounters hard materials and is easily broken. According to statistics, the average cost for each combat board is only 5 days. The use of low-carbon steel processing plates has been improved, and then hard alloys have been surfacing on the surface of the striking plate, which has achieved a good economic effect and the service life has been extended to 40 days. The use of Zigong in Sichuan Province is hard
