Cane sugar; a textbook on the agriculture of the sugar cane, the manufacture of cane sugar, and the analysis of sugar-house products . setting of the trash turner, the caretaken in feeding the cane to the mill, and the means adopted in preparingit for milling. Minor factors are details such as the angle of the crusher,of the carriers, and of the feeding shoots. As regards the actual recordedcapacities of milling trains, as dis-tinct from a mill, a study of a verylarge number of results on recordof nine, twelve, fifteen andeighteen-roller plants, precededby efficient crushers, has led thewTiter to the formula :—Capacity= 0-005 ^ ^^ ^ tons fibre perhour, where n is the number ofmills in the train, I is the length,and d the diameter of a roller ex-pressed in feet. Values of thisexpression, which has no rationalbasis, and is entirely empirical,are given belo\v. If besides capacity the eco-nomics of high efficiency areconsidered, it will be reasonableto obtain this end with longer trains, rather than with larger units, because of the opportunity affordedfor compound maceration.

Let the cane pass from left to right. Let thepressure exerted on the layer of bagasse in its passage between the top andfront roUer be p, and let that between the top and back roUer be n p. Letthese pressures act through the lines joining the centres of the rollers. AlongB A produced lay ofi A D = p. Resolve A D into vertical and horizontal 220 CHAPTER XI components, namely A F and A G.
