Manual screen changer

Manual screen changer, as the name suggests, is to switch the screen changer directly by manual. The manual screen changer has the advantages of small size and low cost, but its shortcomings are also obvious: the screen changing speed is slow, and it generally needs to stop the machine to change the screen. Due to the consideration of friction resistance and sealing performance, the diameter of its screen is generally less than 100mm.

Hydraulic automatic screen changer

The hydraulic automatic screen changer relies on the hydraulic station with complex structure to switch the screen plate or screen column back and forth. Hydraulic automatic screen changer has the advantages of compact volume, good back pressure sealing, rapid screen changing speed and so on. Its shortcomings are relatively more acceptable: high cost, complex hydraulic structure.
