The Model B-050 bench-scale laboratory model roller press can provide conclusive briquetting (compaction) tests on a variety of materials with samples as small as 200g. The design features complete separation of the process zone from the rest of the equipment. Assemblies in contact with the materials being tested are all stainless steel and are easily removable for quick setup changes, cleaning and sterilization. An integrated mixing system accommodates preparation of small batches with binders or other additives, then deposits the mixed material directly into a screw feeder that delivers a precise flow to the compacting rolls.
