[0002] In the mining industry, crushers are commonly used machines. Their main users are to crush mined ores. In order to facilitate the transportation of ores, the ores that have been crushed once need to be crushed for the second time. When the ore is crushed for the second time, due to the relatively small size and volume of the ore, a small crushing station is used for the secondary crushing of coal. The MMD625 double-toothed roller crusher is the main crushing station. Multiple tooth plates are installed on the two crushing shafts of the crusher. Multiple hammers are arranged on each tooth plate to drive the multiple hammers to bite each other when the two crushing rollers rotate, thereby achieving the secondary crushing effect of the ore. The hammer head is a wearing part in the crusher. When crushing ore, the hammer head will often wear out, which will affect the crushing effect of the crusher on the ore and the crushing efficiency. Therefore, it is necessary to replace the tooth plate or repair and weld the hammer head after the hammer head is worn.
