EQUIPMENT DESIGNED TO COLLECT A PREDEFINED QUANTITY OF CLINKER AT KILN DISCHARGE

Several particle size ranges available (Standard: 2-12 mm)

This PHT100 sampler, to be positioned at the fall of the kiln before the cooler, is designed to take clinker samples with a temperature as high as 1500°C. The advantage of taking a sample directly at the kiln discharge is that it considerably reduces the lag time between the clinkerization process and the moment the information regarding the free lime value is known.

This sampler is composed of a refractory steel beam continuously cooled by a blower. This beam is introduced, thanks to two pneumatic jacks, into the flow of clinker and clinker is collected through sampling slots located on top of the beam. The beam is then withdrawn from the clinker flow and collected sample is cooled by blown air and evacuated to a discharge spout with the help of a metallic brush fixed at the end of a jack installed perpendicularly to the beam.

On the top of the beam, sampling slots allow the selection of the maximum particle size of the sample (12 mm as a standard); under the discharge spout a selection grid allows the elimination of the undesired portion of the sample (particle size < 2 mm as a standard) which is then transferred to the drag chain of the cooler.
