During briquetting, granular material is compacted between two counter rotating rollers. Depending upon the material, it may be gravity fed into the rollers or may require precompaction via screw feeders to insure complete filling of the pockets. Some materials may require the addition of a binder to achieve optimum briquette strength.
Sizing and design parameters for each roller press are based on our know-how and experience or as a result of testing the specific material in our pilot plant.
