Abstract
A method and apparatus for forming compressible material into discrete solid blocks or briquettes in which the material is compressed in a compression chamber by a pre-press ram and a main ram. A control system is provided which includes sensors for generating signals that are a function of the density of the compressed and densified material within the compression chamber, and an arrangement which is responsive to the sensors is provided for varying the operation of the material feeding device to change the volumetric flow of material fed to the compression chamber in response to predetermined changes in the density of the material in the chamber.
