Description: |
| Abstract:
This invention relates to sugarcane mills having three crushing rollers mounted in triangular arrangement, and particularly to the method of applying hydraulic pressure to the top roller of such mills. In mills of the above type, the separating force between the rear or discharge roller and the top roller is always in excess of that between the front or feed roller and the top roller, so that the line representing the resultant of these spreading strains is always inclined to the vertical. For this reason, mills have been designed having the hydraulic jacks so placed as to operate at a fixed angle to the vertical, which is supposed to correspond to the angle of the resultant line just mentioned, in order that the pressure may be imposed on the brasses of the top roller journals in a line coincident with said resultant line. It has been found, however, that the angle which this resultant line makes with the vertical is not fixed but varies with the different conditions under which the mill operates, such as the setting of the rollers, the percentage of the fiber in the cane, etc. It is, therefore, advantageous to have the mill so arranged that the angle at which the hydraulic pressure is applied to the top roller may be easily altered to suit these conditions, the proper angle being determined experimentally.
Claim:
In a sugarcane mill, three rollers in triangular arrangement, a. hydraulic jack for imposing a pressure on the upper of said rollers at an angle to the vertical, and means for altering said angle of applied hydraulic pressure. |
