Ringmill American Pulverizer Ringmills utilize an exclusive rolling ring design that is the most efficient crushing element ever developed to reduce material to uniform size. Each ring freely rotates on the shaft and is held in its outward position by centrifugal force.
The ball ring mill has a mill housing, a grinding track (6) and grinding balls (7) which are activated by an outside force and run on the grinding track. For each grinding ball a separate pressure mechanism (8) is provided for transmission of the outside force on the grinding balls. Each pressure mechanism has a ball dome surface as pressure surface acting on the grinding balls.
The Rocklabs Benchtop Ring Mill is a quiet and efficient pulveriser, small and compact enough to fit on a work bench. With a noise level of less than 80dBA and very low contamination of samples the ring mill can be used for pulverising a variety of material.
