露天开采中,爆破后均常有大块岩(矿)石需经二次破碎才能装车外运。到目前为止,这种二次破碎,一直是一件费时、费力而又危险的工作。现在,瑞典的阿特拉斯铜矿公司,已经在生产中采用了一种全新的破碎法,这就是最近在西德慕尼黑召开的一次会议上宣布的“水炮劈裂”法。用这种方法处理大块岩矿石,破碎效果好,生产安全,可望用于各种条件下的矿山和采石场。这种名叫CRAC200型的设备是一种完全机械化的破碎装置,它已在20个国家获得专利。自1979年下半年起,就在瑞典的许多
Open-pit mining, blasting are often large rock (ore) stone to be crushed to load the second Sinotrans. So far, this secondary crushing has been a time-consuming, laborious and dangerous job. Now Sweden’s Atlas Copper Company has adopted a new crushing method in its production, the “Water Cannon Cleavage” law recently announced at a conference in West Germany. Using this method to deal with large rock ore, crushing effect is good, production safety, is expected to be used in various conditions, mines and quarries. The device, type CRAC200, is a fully mechanized crushing plant that has been patented in 20 countries. Since the second half of 1979, there have been many in Sweden
