Lime production

Lime production

Fine lime silo – dusty and corrosive

After it has cooled down, the burned lime is sorted into different particle sizes and stored for further processing. The largest portion is processed to fine lime, which is used in widely different applications in the construction and chemical industries or in farming. A reliable level mea-surement is necessary here for optimal production planning. When combined with moisture, the fine dust forms very aggressive alkaline compounds which over time cause heavy wear on mechanical measuring systems and result in high maintenance costs.

Level measurement in lime silos

VEGAPULS 68 is especially ideal for measuring the coarse limestone rocks and the fine lime stored in the high silos. It measures the levels contactlessly without any wear and without additional maintenance.

For smaller fine lime silos, VEGAFLEX 61 is an interesting alternative to non-contact measurement. The guided microwave instrument delivers reliable level data from the silo, totally unaffected by deposits on the cable and dirt and dust on the process fitting.

Overfill protection with VEGAWAVE 62

The vibrating level switch VEGAWAVE 62 lends itself well for protection against overfilling. It needs no adjustment and switches reliably regardless of the quality of the products stored in the silos. Since VEGAWAVE 62 doesn’t have any mechanical moving parts, it is not subject to wear and tear and is thus completely maintenance-free throughout its entire life cycle.
