The hammer head of the sand making machine in the sand making equipment used in artificial sand making is high consumable. The hardness, toughness and corrosion of the crushed material all affect the service life of the hammer head of the sand making machine. The hardness of the hammer head is not high, and serious wear will occur after a few days of use. If the toughness is not enough, it will break when it hits the hard stone. Some non-corrosion-resistant hammerheads will fail in a few hours when they hit more acidic stone. Therefore, the life of the hammer head directly affects the efficiency of sand making, and it takes a lot of money and time to replace the hammer head of the sand making machine.
