M-Ovas® Grinding System

Your dependable friend in grinding things down.

General

Use NETZSCH grinding systems wherever it is essential that solid matter in fluids be broken down for reliable prevention of pipe clogging and damage to downstream equipment.

The special design of the M-Ovas® housing carries any solids in the wastewater flow to the cutting plate, where they are chopped by rotating blades. This low-maintenance assembly is designed for sludges with a maximum flow of 1300 gpm and a dry matter content of up to 7%.

Advantages of the NETZSCH M-Ovas®:

  • high operating safety due to robust construction
  • ease of operation and simple maintenance
  • low operating costs through high operating efficiency
  • optimal price/performance ratio

The NETZSCH M-Ovas® is primarily used in the following areas:

  • Wastewater treatment
  • Agriculture
  • Slaughterhouses
  • Recycling plants
  • Canning/tinning factories
  • Sugar factories
  • Industrial kitchens

Technique

NETZSCH M-Ovas® - Design

1 Housing
The housing has a hydrodynamic design with integrated stone trap for solids and a clean-out port. The sediment can easliy be removed by opening the cover plate. The housing can be galvanized in stainless steel for corrosion resistance.

2 Housing cover
The cutting unit is integrated into the housing cover. A gas strut is fitted to the cover to assist opening. This allows for easy cleaning of solids in the stone trap.

3 Cutting unit
The cutting plate is made of wear resistant, hardened steel to provide optimum cutting performance by means of a cutting unit with a self-adjusting blade mechanism. The blades are made from wear resistant hardened steel. A flywheel supports the cutting action and reduces the driving power. It is easy to exchange the cutting plate and cutting blades without disassembling the piping.

4 Shaft seal
Hard metal faced mechanical seal with grease quench prevents product leakage.

5 Drive
The standard drive unit is a heavy-duty gear motor with reinforced bearings.

6 In-line version
The product inlet and outlet are positioned on the same level to make piping connections simple and easy. The NETZSCH M-Ovas® can be directly connected to a horizontal pipeline or to a NEMO® Pump inlet.


Applications

The NETZSCH M-Ovas® grinding system is appropriate in any industry where solid matter in the substance can interfere with processing. The design of the housing carries the solids directly to the cutting plate where they are chopped and ground by rotating blades. The M-Ovas®: use it to dependably prevent the clogging of pipes and downstream equipment.

Broad Application Spectrum
The NETZSCH M-Ovas® is used primarily in the following areas:

  • Sewage and wastewater treatment
  • Biogas plants
  • Rendering plants
  • Organic biological waste recycling plants
  • Slaughterhouses
  • Paper and pulp production
  • Agriculture
  • Sugar factories
  • Leather production
