3. Technical characteristics of ball mill
(1) The transmission forms used by the drum mill include edge
leaflet, center drive, multi-point meshing edge drive, etc.; the
drive forms include asynchronous motor + reducer + pinion + large
gear and synchronous motor + air clutch + pinion + large gear;
(2) Generally, the support method of static and dynamic pressure
bearings at both ends is adopted, and a fully enclosed
self-aligning 1200 line contact 'rocker type' bearing is used. Full
static pressure support;
(3) The large open gear is designed according to the American AGMA
standard, equipped with a sealed and reliable gear cover, and
equipped with a glycerin automatic spray lubricating device;
(4) The cylinder is the key part of the mill, and a computer is
used to carry out finite element analysis on it to ensure the
reliability of its use;
(5) The large and medium-sized mills are equipped with slow drive
devices;
(6) Large and medium-sized mills are equipped with high and low
pressure lubrication stations;
(7) The control and protection system adopts PLC control.
