The mill rotor bearings which are mounted in the steel housing are two 2 cylindrical roller bearings nu 316 ecmc3 and one 1 grooved ball bearing skf 6316 c3 the bearings have failed several times over a period of two 2 years before this time the mill had no recorded bearing failures as confirmed by the cmms

The common faults and solutions of ball mill 3rd 11 the ball mill cannot start or the motor overload when starting cause of failure 1 problems with the motor system 2 obstructions in the rotating part 3 when the machine stops for a long time the material and grinding medium in the ball mill are not removed in time and the moisture material condenses into a block

After this initial bearing problem another problem evolved on the output shaft and the decision was made to replace the complete gearbox with a renovated one the gearbox was replaced on the 5th of june resulting in green condition evaluation for all measuring points again there are many different types of mills ball mills rod mills

Acidresistant mills for grinding in raffinate or with acidforming feed as well as special feed and discharge arrangements and special bearing arrangements outotec sag and ball mill outotec highperformance grinding mills use advanced simulation tools for the best possible process efficiency mechanical reliability and maintainability

Heating materials effects the quality of ball mill research paper accuracy and even cause deformation and cracking and other early failure accident materials heat treatment effect the quality of ball mill function is the most thus it can greatly improve the actual material handling bearing capacity to form the aggrandizement layer will improve his weary function its

If a problem is indicated with one technology the team quickly incorporates information from partner technologies to discuss their findings as a group likewise they work together to eliminate the root causes of failure as is the case with the ball mill pulverizers which had produced consistently high failure rates focus on ball mills

Problem 3 ball mill reducer bearing heat solution 3 you can check according to the method of checking the ball mill bearing too high you can also check whether the vent hole of the reducer is blocked and often clear the vent problem 4 after the ball mill motor with the reducer is started the main causes of sudden vibration are as follows

Support bearing rotate the ballscrew 5 by hand if there is resistance or if it binds the bearings are faulty remove the ballscrew 5 and check the support bearings and bearing pack to determine which components need to be replaced

The mill is designed to handle a total ball charge of 3245 t at 100 loading with a percentage filling of 295 in both the chambers both the chambers of the cement mill were charged with 80 of the designed charge

A vibration survey was carried on this ball mill with a duel pinion drive the vibration is high in all planes on both sides of the mill or both pinion drives the measurements were similar in velocity on the motor gearbox and both pinion bearings

Ball mill pinion shaft bearings pinion shaft bearings are of the skf antifriction type mounted in a common twin bearing assembly bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components vbelt driven mills are furnished with an outboard bearing of similar construction

Shellsupported ball mills are becoming the mills of choice over those with trunnion bearings depending on the size of the mill there are two four or six sliding shoes per bearing assembly the expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used sturdy and reliable mill bearing
