Hey, What will happed if the kiln rotate in clockwise ? i know it is stupid question but i asked myself this question several times. What i want to say is there any kiln rotate in clockwise? Is it possible?
Saprina
Yeah! There are many kilns in the world which are rotating clockwise! (viewing from the kiln discharge end looking against the material flow direction). Kiln direction of rotation is decided during the design stage and the cooler centre line is offset with kiln centre line accordingly depending on the direction of rotation of kiln. Considering the drive part, the pinion will be placed on the lifting side (if the kiln rotation is clockwise viewing from discharge end, the pinion will be on the left hand side). Hence kiln direction is uni-directional.
OK, but if we have kiln system with pc and grate cooler (as an example) with counter-clockwise rotation and then we changed only the direction of the rotation to the clockwise direction what will happen? what i mean what will be the effect on the process and production?

Dear Saprina,
There may not be any effect on the kiln production. But, it will have impact on grate cooler cooling efficiency. The availability of kiln will also be affected. If the kiln girth gear is mounted on spring plates and if you have only one pinion driving the kiln then certainly you should not change the direction of kiln rotation. Other than this kiln axial balance of the kiln will also be effected by changing the direction of rotation. Hope I have answered your query.
