We mentioned repeatedly that Energosteel Company conducts constant marketing monitoring of grinding balls market.
Lately there was an increase in instances of procurement of grinding balls of unknown origin that do not have necessary quality certificates. There were also occurrences when supplied product does have support documentation but it is falsified. As a rule, the balls in question are of very poor quality. Using those balls leads to the following consequences:
- occurrence of breakage of grinding media, uneven wear;
- raising of grinding media consumption rate;
- additional purchasing of grind media;
- decline in quality of grinding, reduction of grinding mill productivity;
- choking off the grates installed inside the grinding mill, by scrap from the broken ball;
- metal particles insertion into of the end product of grinding operation;
- damage to the technical equipment (pipes, pumps, sumps etc.);
- increased energy consumption for milling 1 ton of materials;
- ball mill downtime increase for emergency repair work etc.
The situation at hand could happen even with a ball bought from a manufacturer (or its official distributor) and has all necessary quality certificates. But in the case when you are working directly with grinding media manufacturer (or its official distributor) you always can submit a claim and compel the return of balls or recovery of your additional expenses. Otherwise, nobody could guarantee you a proper operation of grinding media, and no one would recover your expenses. And it is the main reason why you always should make a purchase from a reliable supplier (manufacturer or its official distributor).
Energosteel Company experts urge you to be careful. A low price on purchased items is not always a sign of a successful deal.
While purchasing grinding balls you must demand quality certificates issued by the manufacturer. Try to avoid purchasing balls from resellers, as a rule, manufacturers prefer to use direct selling concept. While making a purchase, check quality certification. Verify which regulatory documents (GOSTs, DSTU etc.) are being referenced in certificates.
Also, you can always contact the manufacturer as specified in support documentation for verification of authenticity. You can acquire from the manufacturer following information by certificate number: was that batch of product shipped to this company, precise physicochemical characteristics of grinding media etc.
