随着露天矿的迅速发展,开矿的规模及原矿粒度越来越大;又因复摆型破碎机较简摆型具有结构简单、生产率高等优点,所以复摆颚式破碎机向大型发展的趋向日俱明显。国外已生产了进料口为1700×2100的大型复摆颚式破碎机。我国自五一年仿制复摆颚式(以下简称PE)破碎机以来已能自行设计制造并定型了150×250、250×400、400×600、600×900等中、小型PE型破碎机。近年大型PE——900×1200破碎机也经过了工业性试验。但测试结果
With the rapid development of open-pit mines, the size of ore mines and ore particle size are getting larger and larger. Due to its simple structure and high productivity, complex pendulum crushers have the advantage of large-scale development Day by day obvious. Abroad has produced a feed for the 1700 × 2100 large swing jaw crusher. China since May imitation pendulum jaw (hereinafter referred to as PE) crusher has been able to design and manufacture of their own design and 150 × 250,250 × 400,400 × 600,600 × 900 medium and small PE-type crusher. In recent years, large PE - 900 × 1200 crusher has also been industrialized. But the test results
