PCT No. PCT/DK92/00298 Sec. 371 Date Mar. 23, 1994 Sec. 102(e) Date Mar. 23, 1994 PCT Filed Oct. 12, 1992 PCT Pub. No. WO93/08915 PCT Pub. Date May 13, 1993.For controlling the material feed to a roller press, a method is described, whereby the difference between the operating values of a roller press before and after a forced change in the material feed is used to establish whether the material feed should be increased, reduced or maintained unchanged in order to optimize the operation of the roller press. By this method it is obtained that the roller press, regardless of the homogeneity of the feed material, will constantly be operating within the transition range between starve and shaft feeding and that, consequently, the roller press can be utilized to optimum extent, while simultaneously avoiding the fluidization problems associated with shaft feeding. |
