Why does ball mill have a long-term suspension

Ball Mill running with the long-term suspension, when the length of the ball is not the same. This is due to the different shell temperature rise caused by thermal expansion and contraction. Thus, in the design, installation and maintenance must take into account the thermal expansion and contraction of the barrel of this character. General mill near the discharge end of gear in order to ensure the proper meshing gears, in the discharge end is not allowed in any axial movement, and so are the feed side has to adapt to changing line axial thermal structure. Variable ball axial line hot mill structure, there are two ways to consider: one is to use hollow shaft shoulder and bearing journal between the reserved space to consider. The other is between the bearing and the bottom level of installation of the number of root Gang Gun, when the ball thermal expansion and contraction, the base of the feed-side bearings can be moved along the stick. ball of each position should be to create a mill door (or into the hole). Grinding’s role is framed for the door linings, diaphragm plate, filling or pouring body and stop grinding mill grinding checking warehouses and so on. Mill’s main bearings most commonly used is the sliding bearings, its diameter is large, but the length is very short. Bearing with Pakistan’s gold casting. Sliding bearings with the hongxing difference is that only the lower half of a bush. In addition to bearing the entire bearing with babbitt casting, the rest are made with steel. As the ball of the span and load large, will take place around the song a certain extent, but also manufacturing and installation errors are also difficult to ensure accurate coaxial degree, therefore, auto-aligning bearings made of type, spherical and spherical-watt watt Block Block between the center of a sphere as the center of rotation to be able to move slightly relative to the role and uniform load distribution on the bush.Scientific management, advanced processing technology
