Aerospace Heavy Industries has repeatedly developed and tested the hammerhead of the stone crusher http://equipment hammer crusher, and found some points to be noted to ensure that the performance of the hammer crusher is not reduced.
The hammer head is made of 12-14% manganese-containing manganese steel, and the sandstone equipment http://甩 high carbon steel forged or stamped hammer head is also widely used. When installing, the total weight difference of each two symmetrical hammer heads should be kept within 0.05kg. In this way, the rotor can be easily balanced and the installation and commissioning time can be shortened. In the stone production line http://Product-150.html, the hammer head wears faster and the manufacturing cost is very high. Therefore, the cast iron welding rod is often used for surfacing, thereby saving high quality steel and reducing the cost. When replacing the hammer head, it must be replaced in pairs according to the relative position. Otherwise, the rotor will be unbalanced in rotation, causing vibration and premature bearing damage. Under normal working conditions, the rotor bearing wins below 60 °C and the maximum temperature does not exceed 70 °C. The clearance of the rolling bearing of the hammer crusher http:// is larger than that of the normal rolling bearing, otherwise the bearing will heat up after the machine is running.
