The Waste water Grinder from United Tech Machinery is a high torque, low rotating speed and double shaft grinder under water. It is designed to pulverizing all kinds of solid waste ( clothing, plastic, trash, wood, aluminum can, glass bottle and other debris) to 8-12mm in the modern waste water and sludge to protect pumps, prevents binding and clogging problems. Accommodates high speed water flow while pulverizing various solid waste into particles that let the water flow harmlessly through pumps, pipes and so on.
A
stainless steel wastewater grinder is an essential solution for industries dealing with
solid waste in liquid systems. It ensures
efficient waste reduction,
prevents blockages, and
extends the lifespan of wastewater treatment equipment. With
customizable options, these grinders provide
high performance and reliability for various industries
The Waste water grinder is suitable for Waste Water Treatment Plant, Water works, Rain Pump station and the water inlet channel (well), intercepts floating materials in water, guarantees normal operation of subsequent pump, it's an advance intercepting waste water device.
