EQUIPMENT INTRODUCE

Dy Vacuum Belt Press Filter is a new type press filter which is researched and developed by our company with the patent. It takes the filter cloth as the filtration medium, and removes the water of the filter cake to the utmost depending on vacuum suction and high pressure dehydration area through repeat extrusion and cutting of roller and filter cloth. It is widely applied for dehydration of every kind of sticky-tinny materials, such as industrial filtration and sludge.

CHARACTERISTICS

1.It's high efficient for dehydration because of double gravity predehydration.

2.It's reliable for operation because of "snake" -shape automic deviation-rectifying system.

3.It's convenient for installation and maintenance because of framed construction.
