该型破碎机历史悠久，属传统型破碎设备，电动机通过三角带轮带动偏心轴转动，动颚做周期性复杂摆动产生破碎力。分粗碎和细碎两种机型。该机结构简单，价格较低，工作可靠，排矿口调整方便，更适于破碎潮湿矿、含黏土较多的矿石，破碎粒度相对较粗。我公司对PE400×600，PE250×750，PE600×900等几种类型做了以下优化设计并经实际应用得到认可。

  1.1.1 深腔化设计，破碎比大，破碎效率高，破碎粒度细。

  1.1.2 提高偏心轴转速，生产能力高。

1.1 Product Features

This type of crusher has a long history and belongs to traditional crushing equipment. Its motor drives the eccentric shaft to rotate via V-belt pulley, and movable jaw to carry out periodical complex pendular movement to generate crush capacity. There are two types: coarse crusher and fine crusher. With the features like simple structure, low price, reliable operation, and convenient adjustment of discharging opening, it is very suitable for crushing the damp ore and the ore with a large content of clay, with relatively coarse crushing grain size. We have made the following optimized design for the models such as PE400x600, PE250x750, PE600x900, which has been recognized after practical application.

  1.1.1 Deep chamber design; high reduction ratio; high crushing efficiency; and fine crushing grain size.

  1.1.2 Improved rotary speed of eccentric shaft; high productive capacity.
