Does better nodulisation mean more consistent size of nodules with less dust or with less large nodules ? What might be wrong if always getting a large portion of large nodules (4-6 inches in diameter), even at 25 per cent liquid phase, which isn't high, and ALm of kiln feed ranging from 1.55-1.75. Kiln is typically run at 3.5rpm. The large nodules are only visible on kiln stops when there is a chance to look into the cooler, before the clinker goes through the crusher.

There are two potential causes that I would investigate:
1. a change or variability in the MgO content of your kiln feed, and
2. a change or rise in the Mn2O3 content of your kiln feed.
2. a change or rise in the Mn2O3 content of your kiln feed.

We frequently face with ball formation problem in the kiln for two months. We are studying the case and investigating the parameter changes. What are the possible reasons and the explanation of this phenomenon?

There are certainly precalciner kilns of 1000 to 1400tpd capacity in operation today. Arguably this is well below the optimum economic scale for a kiln and factory but that depends on the local market conditions. It is also feasible to convert an existing long dry kiln. However, many items of equipment would require upgrading: the raw grinding, the kiln feeding equipment, kiln drive, cooler and clinker transport. Unfortunately this usually means that it is just as economic to scrap the old kiln and start afresh. The likely investment for the conversion would depend on many site specific factors. My best estimate would be US$23.5m.
