Cane sugar; a textbook on the agriculture of the sugar cane, the manufacture of cane sugar, and the analysis of sugar-house products . Fig. 106 Fig. 107 occurs, due to the pressure between the top cylinder and the trash turnerfollowing on the elasticity of the crushed cane. This is why c must alwaysbe greater than i. If c becomes too great, then the cylinder 3 cannot takethe feed and will cause a stoppage. The velocity c must be such that theangle A is somewhat less than 90°. The trash turner curve following this argument of Bergmans can be foundgraphically wHh close approximation as follows :

The trash turner curve following this argument of Bergmans can be foundgraphically wHh close approximation as follows :— Draw the positions of the rollers to scale. Fig. 106 ; join OB and OC ;draw KT parallel to OC ; draw KN perpendicular to KT, cutting OC Sit N ;with N as centre and NK as radius draw an arc KM ; then KM is very closeto the original logarithmic Fig. 108 The trash turner itself consists of two parts : the bar, which is a permanentfeature of the plant, and the knife or plate, which is renewable. The knife,a, is attached securely to the bar, b, as indicated in two forms in Fig. 107. The bar runs parallel to the rollers from housing to housing upon whichit is supported. As the bar may be treated as a beam supported at bothends and uniformly loaded, its longitudinal section should be a parabola,as shown in Fig. 108. Vertical stiffening ribs are also generally included. THE EXTRACTION OF THE JUICE BY MILLS 207 In the earlier designs the bar was supported on windows or aperturescast in the housings. The ends of the bar were made with a rectangularsection, and the vertical and horizontal adjustment necessary was effectedby inserting shims or packing strips. In order that the bar might be with-drawn laterally, the window was made deep enough to accommodate the barat its maximum depth, distance pieces being inserted in, and secured by
