What is the effect of the strength of the abrasive on the service life

The strength of the abrasive material in the experiment sand mill is the firm degree of the abrasive particles. When the abrasive blade is very sharp, can withstand the pressure without stripping broken ability. Practice shows that the strength difference of the abrasive, its abrasive grain grinding faster, cutting ability is low, the service life is short. This requires abrasive grains in addition to a higher hardness, but also should have sufficient strength, in order to better grinding processing. The strength of the abrasive will directly affect the amount of abrasive grains and the working hours, so the strength of the abrasive is one of the basic properties of the abrasive.

The strength of the sand mill grinding is used in static load pressure grinding particle method for inspection, namely 5 grams of grinding sample particle onto the surface of a cylindrical disk, put on another cylindrical disc, and then pressurized to 30 kg / cm2, the grinding particle crushing of the portion of the screen to, see the remaining not crushed part weight and total weight ratio to determine the idle ratio is larger, the greater intensity of the abrasive. On the contrary, it means that the strength of the abrasive.
