Tinius Olsen manufactures state-of-the-art Aggregate Polishing Machines. Specimens are manufactured in accurately machined and matched molds. They are then removed from the molds and located on the ‘Road Wheel’.
The wheel is then rotated and enters into contact with a spring-loaded solid rubber tire. Abrasive charges are continuously fed by mechanical feeders at a fixed speed. Feed rates for corn emery and flour emery are as per British and American standards. The water is supplied at a controlled rate through a water container. Used water and abrasives are collected in a large removable tray.
