Product Description

Double plate two working station hydraulic screen changer

Specification
1)Leak-free mold
2)Continuous production without activity machine halt
3)Easy operation and labor-saving
4) Short material residence time
5)Flow channel without dead spots


Features Included
1)There is one screen pack on each slide plate, and the the two screen pack work simultaneously, when screen change needed , they are replaced one after the other.
2)The unique sealing system make a perfect sealing effect, guarantee leak-free operation under high pressure.A remarkable reduction in maintenance costs have been possible thanks to the perfect sealing system.
3) In comparison with the double pillar screen changer, the GT-DSP series of double plate hydraulic screen changer allows a quicker screen change. This advantage is based on the optimized volume of filtering chamber, which minimized the duration of the venting procedure.
4)Air venting procedure defuse the gas mixed in the raw materials and improve the quality of the product.
