Double Screen Drum Sewage Grinders-2

Double Screen Drum Sewage Grinders

The double-screen drum sewage grinder adopts a double-drum structure, which is mainly used for decontamination equipment in municipal, water conservancies, pumping stations, and other systems. Running, the pulverizing grid decontamination machine can crush the suspended and floating garbage in the sewage into fine particles of 6-10mm, and the pulverized dirt does not need to be salvaged, and directly flows away with the sewage.

The double-screen drum sewage grinder is truly in a sense, the whole ground is buried unattended. The double-screen drum sewage grinder can be installed at the bottom of the pool, and the top of the pool can be closed, which greatly changes the defects of the traditional pumping station, such as poor working environment, loud noise, high construction cost, and high operating cost, etc.

  • The sewage grinder includes cutting blades, gaskets, shafts, vertical rotary water grids, bearings and seals, bases, casings, reducers, and motors.

  • The shredder blade of sewage grinders is a  two-axis design that operates continuously under dry/wet conditions. The cutting blades and shims are single piece separated.

  • Two independent cutting blades and shims are mounted on two parallel shafts that alternately overlap to achieve a helical cut. The driven shaft is rotated by the driveshaft to rotate at a speed of 2/3 of the drive shaft.

  • Can be used in sewage lifting pumping station
