Powerful, Industrial Grinding for High-flow, In-line Applications

4-HYDRO in-line, dual-shafted grinders reduce industrial wastewater solids into small particles using slow-speed and high-torque grinding action. These in-line grinders are engineered to handle high-flow applications with challenging solids that impede pump, valve, centrifuge and heat exchanger performance.

The 4-HYDRO protects pipeline equipment from damaging solids in sludge, slurries and waste materials to keep industrial processes running smoothly. Its efficient solids reduction also improves solids recovery and dewatering.

Typical applications include:

  • Drill cuttings
  • Oil sands processing
  • Petroleum processing
  • Pulp and paper mills
  • Chemical plants
  • Fish/beef/poultry processing
  • Manure
  • Recycling plants

Benefits

  • Prevents unplanned equipment maintenance and process downtime
  • Protects pumps, valves, centrifuges and other downstream equipment from damage and clogs requiring costly repairs
  • Preconditions sludges, slurries and waste materials for improved solids recovery and dewatering

Features

  • Dual-shafted, slow-speed, high-torque grinder easily shreds the toughest solids, including rocks, wood, plastic, animal waste, plant waste and other debris
  • Compact footprint allows installation within most process pipeline systems
  • Smart controller with load-sensing control system optimizes performance and protects against jams
  • Available Wipes Ready® Technology shreds fibrous, sinewy and stringy solids bi-directionally into small pieces preventing materials from reweaving in the waste stream to form long strips
  • Customizable cutter stack configurations maximize grinder performance
  • Global motor and controller options meet local energy efficiency and regulatory requirements
