INCORRECT FORMULA % calcination = (fkiln feed – dsample)/ fkiln feed x The formula is incorrect because we’re assuming the difference in weight between the two samples is due entirely to the calcination process. That’s much too simplistic. Some of the weight loss is indeed due to calcination but there’s also weight loss in the sample

The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends.
