What Is the Deval Attrition Test Used For?
Highway engineering and materials laboratories use it to measure how well coarse aggregate resists wear when particles rub against each other and against the abrasive charge. A weighed sample is loaded into the cylinders with the charge, the covers are fastened, and the machine runs for a set number of revolutions; the fine material produced is then sieved out and weighed to give the percentage wear. Check the covers are tight before each run.
Frequently Asked Questions
Why are the cylinders set at an angle?
Mounting them at 30° to the shaft axis makes the sample and abrasive charge tumble from end to end as the shaft turns, so the particles grind against one another.
What power supply does it need?
It is designed for a 440 V, 3 phase, 50 Hz AC supply, and the connection should be made by a qualified electrician.
What is supplied with the machine?
An abrasive charge of 12 pieces; both cylinders also have tight-fitting covers to hold the sample in.
