1.Shred solids in wastewater,no need to collect waste and deliver 2.Protect pumps,no pump house,no flies,no odors,low noise
Construction
The wastewater grinders are assembled by motor, reducer, gear box, cutting chamber, drums,mechanical seal, shell, PLC etc.
Principle
The power from the motor buffered by the reducer actuates the driving shaft. Then the driving shaft actuates the driven shaft so that two groups of cutters equipped in the driving shaft and the driven shaft rotate in opposite directions. When the captured solids enter the cutting chamber the solids are grinding and crushing into tiny particles.And the fluid flows through the space between cutters, side rails and drums.
Materials
l Cutter and spacer: heat-treated alloy steel 4130 with surface harden evenly
l Shaft: heat-treated alloy steel 4140 with surface harden evenly
l Mechanicals Seals: Tungsten Carbide faces
l Side rail: Ductile cast iron ASTMA 536
l Shell and Housings: Ductile cast iron ASTMA 536
l Screening Drums:
• Standard: coil made of stainless steel: 304
• Optional: perforated, stainless steel drum with diameter 6mm openings
Control System Function
