Channel Monster™ Open channel grinders

Powerful grinders for pump stations and headworks

Channel Monster™ sewage grinders represent the best-in-class technology for wastewater solids reduction. The patented Channel Monster uses rotating screening drums to capture solids and direct them into our proven dual-shafted grinder. The result is a high-flow capacity system that can handle typical solids loading as well as tougher solids like wood and occasional rocks.

Main benefits
Dual-shafted grinder
  • Proven low-speed, high-torque dual shafted grinding which can shred the toughest solids
  • Grinds debris smaller than single-shafted machines
  • Grinding separates organic from inorganic materials in the waste stream
High-flow screening drums
  • High flow screening drums to prevent bypass of unshredded solids without compromising flow
  • Standard stainless steel 12 mm perforated drums
Automated monitoring and controls
  • Protect pumps and other critical equipment from costly clogs and damage from tough solids
  • Auto load sensing reduce interrupts and protects the system from damage
  • Adaptive to custom requirements and plant SCADA systems
  • Stores operational data
Wipes Ready™ technology
  • Wipes Ready technology available which prevents materials from forming long strips and reweaving in the waste stream
Lower operating cost
  • Clear pipes and pumps means shorter pump run cycles and lower electrical costs
Main applications

The Channel Monster™ sewage grinders are designed to capture and grind down the toughest wastewater solids in high-flow systems such as:

  • Pump stations where tough solids need to be ground up
  • High flows at the plant’s headworks
Wipes Ready™ Technology

Channel Monster sewage grinders are available with the unique Wipes Ready™ suite of technologies. It was designed to capture all wipes in the waste stream and shred them into small pieces that will not reweave into a ragball in sewage systems.

The Wipes Ready technologies applied in Channel Monster sewage grinders are:

  • Wipes Ready cutters* – A combination of serrated cutters and knurled spacers cuts wipes in two directions. The result is smaller particles that cannot reweave downstream.
  • Delta P Side Rails* – Direct solids into the cutters without sacrificing flow rate and prevent debris build-up in the grinder
  • Optimized cut control (OCC)* – The OCC gear ratio optimizes shaft speeds to enhance the cutting action and cleaning of the cutters, which in turn improves the performance and life of the grinder.
