Lime production

Lime kiln – optimal filling saves costs

Whereas in cement production the raw flour is burned to clinker in long, rotating furnaces, lime burning is carried out mainly in vertical, stationary shaft furnaces. The furnace is filled from above and the burned limestone discharged at the bottom of the furnace. Optimal filling is an important prerequisite for efficient operation of the furnace. Due to the sometimes very high temperatures and rough operating conditions, the demands on the level measuring system are very high.

Non-contact level measurement with VEGAPULS 68

The robust radar sensor VEGAPULS 68 delivers reliable measuring results even under the extreme conditions in the lime kiln. The sensor detects the surface of the limestone reliably and provides the data that are so important for effective operation of the furnace.

Level measurement with SOLITRAC 31

If measuring from above is not possible, the level measurement is realized with a radiation based device. In this procedure, radiation from a radioactive source passes through the medium, which attenuates it. The degree of attenuation, and thus the level, is determined by a detector – from the outside, without any contact to the medium.

The source holder VEGASOURCE 31 houses the radioactive source, which is optimized for the specific application. Its robust construction ensures 100% reliable protection of the surroundings.
