ABRASIMETER

PEI series

 It is a laboratory instrument suitable for carrying out tests according to the P.E.I method, UNI EN ISO 10545-7 and M.C.C. on several samples at the same time (3 or 4 samples depending on the model). 

 The standard provides for the execution of the test by subjecting the glazed ceramic material to wear obtained through an abrasive charge consisting of corundum, steel balls of various diameters and distilled water.  The sample is blocked by a rubber surface wedged in a special support, containing the aforementioned abrasive charge. These supports (in variable quantities depending on the model of the instrument) are placed on a plate in an offset position with respect to the central rotor.  This type of tangential rotation allows the charges to carry out the abrasion on the sample.
