The wheel is now rotated and enters in contact with solid rubber tyre, spring loaded.
Abrasive charges are continuously introduced by two automatic mechanical feeders (hoppers).
The feeders are held by a suitable support disjoined from the machine body; this solution saveguards feeding calibration and realiability/life of the hoppers from the influence of test execution vibrations.
The water is supplied at a controlled rate through a water container equipped with flow regulator.
During the test execution the display shows the remaining time and the speed rotation of the wheel holding the specimens.
Supplied complete with 2 rubber wheels (one for corn and one for flour emery), set of 4 specimen moulds and 2 mould covers, while control stone, corn and flour emery.
