The tester is which can evaluate resistance of abrasive and eroding of refractories, and reflect the ability of abrasive resistance an high temperature. The tester is not only used to test the abrasive resistance of refractory products at room or high temperature, but also suits to test castable refractory and plastic refractory.
The basal principle of the tester is equal with Chinese standard GB/T 18301-2001 Test method for abrasion resistance of refractory materials at room temperature, and international standard ISO16282:2007 Test method for abrasion resistance of refractory materials at room temperature.
