Fine grinding of recycling glass

spangler-editor — Tue, 10 Jan 2023 09:04:06 +0000

In 2022, Schirmbeck GmbH has extended its glass recycling to include a finest grinding process. For this, we coupled the controls of the mills, the conveyor systems and the silos with our master control and added a uniform visualisation.
Due to the very fine grinding of the glass and the dust produced, we have designed a strong aeration system which avoids deposit of fine glass particles in the control cabinets.
Process data and messages of all plant parts are displayed on our control unit and reflected on the PC in the central office.

Mining Peru

We configured the controls for the wastewater treatment plant and the ore-washing plant and designed them according to US regulations UL 508 A and UL 698 A. The scope of delivery included three switch and control systems.

One of which was built double-walled in stainless steel to reduce heat input under subtropical climate conditions.
Two Allen-Bradley ControlLogics control systems which are connected redundantly were used.

The system controls five filter step screens, two conveyor screws and two wash presses for the wastewater treatment.

The tight safety measures in mining have shaped the whole nine-month project. Just for on-site commissioning activities, a three-day safety check had to be completed in advance by our employees.

Glass sand processing Azerbaijan

Absolutely pure quartz sand and a constant grain structure are the requirements for “crystal clear glass”. Even the smallest impurities can cause large variations in colour. In a complex process, the treatment plant processes the degraded good to quartz sand of the highest purity which is ready for production.

The plant was planned and manufactured according to customer needs without a PLC system. We installed a total of 1,600 relays, i.e. the logic was constructed by us step-by-step using hardware, and visualisation was achieved using a mimic diagram.

Sifting and classifying systems lead to enormous mechanical stress on the system. For this reason, the entire control technology was pooled in a separate electric container and installed away from the production flow.
