Abstract
A piston press system and a test method using the same are used for predicting the roll service life of high-pressure grinding rolls. The method is based on the same comminution mechanism of inter-particle layers compression as the heavy equipment high-pressure grinding rolls to simulate the grinding process of the studded high-pressure grinding roll, realizing that the coverage area of studs accounts for 16% to 20% of the compression surface by disposing tungsten carbide upper studs and lower studs, better restoring the simulation process and effectively realizing the roll service life prediction of the heavy equipment high-pressure roller mill with a small quantity of materials.
