Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of Owers and other materials.1 grind-able. When ball mills are running, regularly hit sound loud comes from the machine, the reason is some liner bolts is 570s. You can judge the position of liner bolt based on the sound resource, and then find it and tight it up.2. The temperature of ball mills and engine bearing is rising and exceeds regulation. In this case, you can touch the machine to judge the heated parts are over whole or just partly. Learn more on the subject from Alipay. Settle the problems with these methods as follows.(1) Check all the lubricating points, if the using oil specifications are complies with equipment instructions or not.(2) Check if the lubricating oil and grease becomes bad.(3) Check if lubricating road is keep, and if lubricating oil directamente enters into lubricating point. Oil shortage will cause machine overheated.(4) Side gap between ball mills and bearing bush is too small, and the gap of bearing bush and bearing is too large.
As a result, the contact points are too much to form evenly oil film on the bush.(5) The reason can also be the amount of roller bearing lubricating oil is too much or too little. Too much oil will generate heat and hardly dissipated amount. Too little oil will cause poor lubrication. So, we should add enough oil as regulation, generally the amount is 1/3 1/2 of the bearing gap.(6) Two ends of ball mills body is too tight in sealing, or sealing body contact directly with bearing, can cause overheated.All the above problems should be solved according to different reason.3. Ball mills reducer bearing overheatExcept checking it according to ball mill heating methods, we should check gas discharging port check of reducer. If it is clogging, we should keep it clear.4.
Ball mills vibrates when engine starts reducer, the main reasons are: (1) The gap of two wheels is connected too small, as a result, it can t compensate driving power. (2) The method of shaft coupling correcting is not right, which leads to unconcentric of two bearings. (3) The connecting bolt of shaft coupling is not fixed tight equally, and the tight degree is different. (4) Ball mill bearing outer ring is flexible.Settlement: adjust gap of two wheels as statement, and make them concentric instruction. Fix the connected with equal force bolts tight.
