固定式液压破碎机的开发研制及其应用

在露天采矿中，大多采用爆破法将矿石从岩体上爆落后，由运输车辆运至破碎厂，经过固定格筛后进行初碎。由于爆破等原因，产生的大块矿石有时卡在格筛处不能落下使破碎流程中断。在地下开采中，矿石爆破后同样会产生大块，大块有时卡在溜井口不能落下，有时卡在溜筛处及各种格筛处，严重影响正常生产。固定式液压破碎机，就是为了解决大块卡格筛、卡溜井口而研制的用在露天矿，也可用在地下矿的新型高效二次破碎设备。

Development of Fixed Type Hydraulic Crusher and Its Application in Mines

In open-pit mining, it is a common practice to use a blasting method to blast off the ore from the rockmass, which is then transported to a crusher plant for a primary, crushing after the classification by a grate grizzly. Due to the blast-related causes, the large fragments of ore sometimes can not pass the grizzly, leading to the interruption of the crushing process. In underground mining, large fragments of ore can also he produced, which may block the ore-pass opening, sluice screens or various grate grizzlies, thus seriously affecting the normal production. It is right for solving such problems that the fixed type hydraulic crusher is developed, which can also he used in underground mines as an new efficient secondary crushing machine.
