经我厂技术人员的努力，对国家定型产品PEX250x1000细鄂进行改造，利用曲轴的原理，把力分为两次做，减少电机的功率，提高了转速，增加了破碎的细度，提高了产量，真正实现了降耗增产。新机型机架同原PEX250x1000机架尺寸相同，原基础不变，可以互换使用。
   该机经近百家厂方使用证明，安全可靠、高效节能，是水泥厂、矿山采石等行业优选的设备。

  With the hard work of our technician,improving the product PE*250*1000 jaw,using the theory of axe to devide the force to two parts,reducing the power of the motor and enhancing the rotate speed,we rise the output and realise the reduction of the comsuption and adding the output. The new machine?size is same as the old PE*250*1000 machine,the former thing isnot changed and they can be used mutually.
  The Machine is used by nearly 100 factories to verify that is safe,relible,hight effciency and saving energe,so it is the best choice equipment of the concrete and mine.
