Glass Grinding

At an Optical lens customer mineral mold’s will be processed (grinded) for before they can be used in the manufacturing process, here the request been to manufacturer a “emulsion supply system (located in the 1st floor)” for the production (2nd floor).

This Emulsion supply include a pre-sedimentation tank with more then 1000 liters of volume, the emulsion in the pre-sedimentation-tank is kept on a fixed temperature by circulating the emulsion with a pump over a Pipe-heat-exchanger back into the tank, in addition, 2 supply pumps are installed that work redundancy. These pumps are monitored by 2 pressure switches. As soon as the pressure of one pump drops and / or the pump fails, the second pump starts immediately to secure the supply of the grinding emulsion directly to production in the second floor, this provides certain safety and minimize the downtimes.

The emulsion from the production machine will return back into the pre-sedimentation-tank by gravity, at the bottom of the tank outlet pipe & automatic drain valve supply contaminated emulsion and glass solids into a STA -S15 Centrifuge separator, the production regularly need to check the solid content of the emulsion, to keep the solid content of the emulsion within a proper range, a too low / too high solid content is bad for the grinding process, therefore the separator only be operated frequently on time basis by the operator.

Once the cleaning cycle time of the centrifuge separator end, the operator will be informed by a flashing light indication, the operator now opens the separator replace the dirty sludge insert by a new sludge insert which approximate take 3-5 minutes and the equipment would be ready for the next separation cycle. The separated sludge (glass dust) can easily be disposed and the insert can be cleaned.

The separated glass sludge in the basket, various weights from 1-12Kg can be separated
with our Centrifuge Separator S15 per cycle.
