Macerator Channel Series Grinder Main applications The macerator channel series grinder is a high torque, low speed grinder with the ability to effectively macerate raw sewage, sludge, sewage screenings and industrial process flows. The macerator channel series grinder is used in the following applications: Protection of pumps and systems in transport and treatment wastewater applications Imported sludge transfer applications Inlet works in-flow Industrial wet waste grinding and maceration Features and benefits Prevents clogging and blockages downstream of the macerator, reducing unplanned maintenance Supplied with a PLC to protect against damage from unexpected materials and overloads Industrial bulk waste reduction and savings realized through waste recycling Shafts operate at different speeds, typically 50 to 80 rpm, with the cutters to provide a tearing action on the solids Option for the in-channel design to be adapted with inlet and outlet flanges can be supplied Materials Casing Cutter and spacers Shafts Mechanical seals Cast iron Chromium molybdenum steel, hardened to 45-50 HRC, spacers hardened to 41-46 HRC Alloy steel hardened to 55-59 HRC Tungsten carbide face, stainless steel cartridge Ferralium (optional) Gun metal (optional)
Macerator - Pipeline Series Grinder Main applications The macerator pipeline series grinder is the latest generation of twin shaft grinders and specifically designed for efficient treatment of abrasive sludge. The macerator grinder is designed to be maintained in place without disconnecting from pipework. The macerator pipeline series grinder is used in the following applications: All applications where raw sewage, sewage screenings and sludge maceration is involved Protects pumps and sludge treatment process, filters, digesters and equipment Fine grading of sludge for digestion plant In-pipeline applications Features and benefits With twin shafts, slow speed and high torque, the grinders provide positive displacement solids grinding Protects pumps and sludge treatment process, filters, digesters and equipment Maintain in place with quick removal of rotating wear items With angled cutter shafts, the slope of the cutters ensures any rejected material drops clear of shafts and cutters, preventing damage Designed with a built-in trap to catch rejected material and clean out port, for easy maintenance within sewage collection, inlet works and sludge treatment processes Low running speeds, hardened cutters and efficient low kw motors Materials Casing Cutter and spacers Shafts Mechanical seals Cast iron Chromium molybdenum steel, hardened to 45-50 HRC, Spacers hardened to 41-46 HRC Alloy steel hardened to 55-59 HRC Tungsten carbide face, stainless steel cartridge 4140 plate Ferralium or Stainless steel (optional)
Maintain in Place To minimize the time and cost involved when maintaining a conventional grinder/macerator, the macerator pipeline series grinder can easily be maintained in place, without disconnecting or removing any pipework. Currently, the removal of the cutting elements from a typical grinder/macerator requires removal from site and can take up to two days to complete. With the macerator pipeline series grinder, the complete cutter stack can be inspected and replaced within two and a half hours. 1. Clear access to cover screw 2. Remove retaining screws 3. Remove large access cover for visual inspection of cutters 4. Loosen and remove shaft lock nuts 5. Remove cutters and spacers 6. Inspect/replace cutters, spacers and shafts
