Pipeline Series

Macerator - Pipeline Series Grinder

Macerator grinder designed to be maintained in place without disconnecting from pipework. For protection of downstream pumps and equipment, and promotion of improved digestion in raw sewage systems by the fine grinding of sludge.

Construction

Twin shaft, pipeline macerator. Slow speed, high torque, fitted with interleaving cutters and spacers, and designed for connection to inlet and outlet flanged pipework from 100 - 300 mm.

Applications

Typical applications for the macerator - pipeline series grinder include:

  • All applications where raw sewage, sewage screenings andsludge maceration is involved.
  • Protects pumps and sludge treatment process, filters, digesters and equipment.
  • Fine grading of sludge for digestion plant.
  • In-pipeline applications.

Features

  • Maintain-in-place design. Pull-back cutter stack allows removal for maintenance without disturbing the pipeline.
  • Angled cutter shafts. The slope of the cutters ensures any rejected material drops clear of the shafts and cutters and prevents damage.
  • Built-in trap and clean-out port catches rejected material.
  • Access cover plates on either side of the trash trap.
  • Low running speeds, hardened cutters and efficient low kW motors.
  • Full access inspection port (T01C).

Motor / drives

  • Drive to the machine is provided to one shaft by a helical/worm gearmotor, and divided between shafts using spur gears of case-hardened steel.
  • Low running speeds reduces wear, for a longer working life which extends the periods between routine maintenance. Important in heavy cake applications
