Wastewater Grinder

Operation Principle

1. Solids enter grinders through open channel;

2.Solids pass through cutters for size reduction.;

3.Solids are cut into smaller particles and no threat to downstream equipment.

Materials of Construction

Motor: Customized, multiple power options

Reducer: Planet gear reducer, good ability to against the load impact

Cutter and spacer: heat-treated alloy steel 4130 with surface harden evenly.

The hardness is not less than 45~50HRC

Shaft: heat-treated alloy steel 4140

Mechanicals Seals: Tungsten Carbide faces

Housings: Ductile cast iron ASTMA 536

Frame: Stainless steel(304,316)

Mechanical Characteristic

Ease and Flexibility of Installation

     Adapts to most existing pipelines with little or no modification

Mechanical Seals

     Pressure capability up to 6.3kg/cm2;

     No seal flush required and no packing gland to adjust;

Manhole

    Manhole diameter: 1.2m

    Wall thickness: 12mm

Dual Shaft Design

    Low-speed, high torque grinders handle rags, rocks, wood,clothing, plastics and other debris

   Capable of handling a wider variety of solids than single shafted machine

Cutter Options

    Customized cutters with various tooth configurations to meet special application
