Riva - Miniroll Roller Compactor

Roll Compactor Laminating and Granulating Equipment

Laminator and granulator for Research and Development and small production batches.

Minimum processing capacity of 0.5kg to 20kg.

Manufactured under GMP regulations, this laminator and granulator has a tubular steel structure coated in hard chrome. The Riva Miniroll R&D roller compactor contists of a loading hopper, an extrusion press to force out the air trapped within the material, a grip area and roller cylinders to laminate, with a cutter and chopper and sieve to granulate the material.  The Miniroll R & D roller compactor features a compact design in the isolated compressing zone. Due to the simplicity of the front assembly construction design, the compressing rolls are quickly and easily changed. The particle size of the granules can be modified by interchangeable rollers, varying the cutting and granulating roll speeds, or  the size of the seive mesh which are interchangeable.

The PLC controls the start and stop algorithm in sequential mode for the three motors powered by the independent frequency adjusters. Parameters controlling both the motor speeds and the compression force of the rolls can be stored as files, with a maximum capacity for 99 products.

The machine works on a single-phase power line, which is supplied with a hydraulic electro-pump to adjust the compression force.
