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.
Claims6
A method of forming a compressible and cohesive material into discrete solid briquettes, said method comprising, in the following sequence, the steps of:
- (a) providing a generally confined compression chamber;
- (b) feeding said material into said chamber at a predetermined volumetric flow;
- (c) moving a first ram into said chamber to initially compress and densify said material therein;
- (d) generating a first signal that is a function of the density of said material in said chamber;
- (e) comparing said first signal to a signal corresponding to a predetermined density;
- (f) decreasing said flow of material fed to said chamber in response to said first signal indicating that said density of said material in said chamber is above a predetermined level;
- (g) moving a second ram into said chamber to compress and densify said material therein into a briquette having a predetermined volume;
- (h) generating a second signal that is a function of the density of said material in said chamber;
- (i) comparing said second signal to said signal corresponding to a predetermined density;
- (j) increasing said flow of material fed to said chamber is response to said second signal indicating that said density of said material in said chamber is below a predetermined level, and decreasing said flow of material fed to said chamber in response to said second signal indicating that said density of said material in said chamber is above a predetermined level.
