Vomat System Recycles During Grinding Oil Filtration

When filtering grinding oil, for example, when grinding carbide tools, the material to be filtered has long ceased to be hazardous waste in Vomat’s filtration system. In this system, the valuable carbide can be reprocessed. Not only is the oil filtered, but a specially designed sludge collection system (Sedimentator) also enables sustainable recycling, which saves costs and makes an important contribution to the environment, the company says.

Vomat uses durable, high-performance, pre-coat filters for the filtration of grinding oils. If required, the offerings include HSS pre-filter for mixed carbide and HSS production. The system separates 100% of the clean and dirty oil in its full-flow process. Flushing and filtering takes place as required on an automatic cycle, depending on the amount of sludge accumulated in the filters and is also energy optimized. The temperature control keeps the oil temperature constant within the set range at all times. 

The company’s filters are designed so no additional filter aids are required to keep the oil for an extended period of time in the system at fresh oil quality with a particle size of 3 to 5 microns. Because of the way Vomat designed its cooling systems, there is no critical heat input into the cooling medium. All this combined are basic principles for efficient recycling of carbide."

In the Sedimentator, the grinding sludge has a residual moisture content of only 5 to 10 percent after settling. The filter system can continue to run during the disposal of carbide sludge. The sludge is directly deposited into a suitable transport container ready to be picked up by a recycling company. 

Vomat systems are distributed by Oelheld in the U.S.
