商品介绍
The working principle of the Deval abrasion testing machine is to put a stone sample of a certain specification and steel balls into the abrasion cylinder together. The abrasion cylinder rotates at a certain speed. During the rotation process, the stone sample and the steel balls collide and rub against each other. After a specified number of rotations, the mass loss of the stone sample is determined to measure the abrasion degree of the stone.
