Single Screen Drum Sewage Grinders


The single-screen drum sewage grinder adopts a single-drum structure, which has superior performance and is easy to install. It is composed of a drum grid and an alloy cutter pulverizer, which can crush difficult-to-handle solid impurities into small particles.


The unique design of the single screen drum type sewage grinder improves the capture rate of solids, increases the flow rate, prevents objects from being entangled, better protects subsequent equipment, and greatly reduces use and maintenance costs.



  • 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.
