Working principle:

1.  Solid wastes contained in wastewater enter the YFL non screen drum channel sewage grinder through open channel.

2.  Double shaft blades shred the solid wastes by rotating in opposite direction.

3.   Solid wastes are reduced to 6 mm-12 mm tiny particles without threat to downstream equipments and pass through the grinder.
