For some PULSES PROCESSING EQUIPMENT which mainly grinds bean kernels, the grinding roll has great importance. Excellent pulses processing equipment grinding roll can make pulses processing more effective and the end products have higher quality. Therefore, when we choose the spare parts for the pulses processing equipment, we should choose the high quality grinding roll first.

However, in grinding roll choosing, many people always like to choose the one with high hardness. In fact, what we should choose is the grinding roll with good abrasive resistance. The hard-wearing grinding roll has longer service life. But the grinding roll with high hardness may not have good abrasive resistance. Oppositely, some grinding rolls with high hardness are always easily abraded. And because of the high hardness, the grinding roll abrasion may be more serious caused by the rolls crashing. But in the guarantee of the roller wear resistance, the pulses processing equipment will have higher working efficiency for its higher hardness of the grinding roll.

Therefore, the high hardness of the pulses processing equipment grinding roll doesn’t mean the higher quality of the grinding roll. With respect to the hardness, the wear-resisting property is more important.
