Dear Sirs, I am finding an unusual occurrence in the Auxiliary gearbox of a Ball Mill. The input shaft of the auxiliary gearbox once broke into two pieces on Nov'20 and then I replaced the input shaft with a new one which got bend last week.
be slightly smaller. Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-ameter mills allow for use of gear ratios not normally thought possible in sin-gle-reduction applications — namely, 8:1 to 20:1. If the gear is to replace an existing gear, then manufacturing drawings or
The gearbox design presented in this report is a result of considerable amount of experimental iterations based on stress analysis knowledge and the team's ability to manipulate the provided data into a feasible well-performing solution. The design achieves most of its initial goals except for the weight reduction requirement.

The big gear of the ball mill fits on the mill shell, the size is bigger, the big gear is divided into half structure, the radial and axial run-out of the big gear are controlled within the national standard, the aging treatment is up to the standard, and the stress and deformation after processing are prevented.
mills and ball mills for use in the mining and cement industries. By current stan-dards, girth gears can be as large as 14 meters (46 feet) in diameter, 1.1 meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on the mill structure to pro-

Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
