4. The hydraulic adjustment device. Use of hydraulic cylinder and piston unit, adjust the discharge port, this law applies to hydraulic jaw crusher.
In recent years, China's production of cement guessed for crushing and fine crushing of materials Wide crushing jaw crusher, it is compared with the same specifications pe-type jaw crusher with crushing ratio amounted to less dust, high yield, small abrasion and other characteristics, has been widely used, and has formed a new series -pex type crushing jaw crusher.
