Vacuum Evaporator Treats Wastewater
IMTS 2018: PRAB Inc.’s Evaled vacuum evaporation and distillation system treats wastewater in a range of industrial applications.
Prab Inc.’s Evaled vacuum evaporation and distillation system treats wastewater in a range of industrial applications. These include exhausted oil emulsions, tumbling baths, part-rinsing waters, ion-exchange regeneration, pretreatment baths, pickling baths, rinsing baths (cyanide, copper, zinc, nickel, cobalt, cadmium, chromium) and more. The evaporator operates as a closed-loop system under vacuum. It has one inlet, one concentrate discharge stream and one distillate discharge stream. According to the company, it does not produce air emissions. A water analysis is performed to determine equipment requirements. The company provides energy-efficient and zero-liquid-discharge models for treating process and wastewaters.
Minimum quantity lubricant can save money, improve tool life and improve the part finish. But it may involve changes to both the equipment and the processing strategy.
An add-on system for minimum quantity lubrication (MQL) combines an external pump with repeatable control over nozzle position.
An expensive lesson that many shops learn too late is that the automatic oil system on their CNC machine tool may not be completely automatic. Since the automatic oil system is designed to give a warning when the oil tank is empty, many machinists simply assume all is well if the alarm doesn't go off.
