The grid ball mill is equipped with a bearing end cover with a hollow motor shaft at the discharge end, and a rolling bearing inner pad and a discharge square. The discharge grid of the grid ball mill is composed of a management center jaw, a square jaw, and a dustpan shaped jaw. Eight radial ribs are cast on the inner cavity of the bearing end cover, dividing the bearing end cover into eight fan shaped chambers. A dustpan shaped plate is installed in each fan shaped chamber and fixed on the bearing end cover with screws. Then, the square plate is installed on each fan shaped chamber generated by the dustpan plate.
The wet grid ball mill is equipped with a slow speed transmission system, which can achieve a speed ratio of 0.1r/min for the cylinder section, making it easy to trip, repair, or loosen the load. The wet grid type ball mill uses hydraulic jack equipment for lifting the rotating part during maintenance. The wet grid type ball mill can save expensive large and medium-sized Overhead crane.
The wet grid type ball mill has a feeding square at the feeding end of the cylinder body, and is equipped with anti spiral twisted dragon blades on the inner surface of the hollow motor shaft sleeve, which can return the overflow balls and coarse ore blocks of coal slurry back to the ball mill. Generally, cement ball mills with a diameter of 900-2100Mm or motors with a rated power of less than 400KW for wet grid type ball mills are driven by Y series products with high operating torque and JR asynchronous motors, with a primary reducer in the middle and connected by a coupling.
