ATTENTION! UNETHICAL COMPETITION ON THE UKRAINIAN GRINDING BALLS MARKET

September 12, 2019 · Archive · 0 .

Following the trends of the market for increasing the requirements for the grinding media quality, a lot of sale offers for the steel grinding balls with a fifth hardness group (DSTU 8538-2015 and GOST 7524-2015) have appeared on the Ukrainian market.

It should be noted, most manufacturers have not mastered production the grinding balls with the fifth hardness group (DSTU 8538-2015 and GOST 7524-2015). That’s why there are very often the grinding balls with the fourth hardness group sold to a client as the grinding balls with the fifth hardness group, whose characteristics (especially surface hardness) slightly exceed of DSTU or GOST. This is easily achieved by violating the technology of quenching and tempering the finished products. Such grinding balls have high surface hardness, but toward to the centre, the hardness decreases exponentially. Such grinding balls are most prone to split, during working in a ball mill.

We recommend the capabilities analysis of the new supplier before accepting the grinding balls purchase from him. This is easy to do without resorting to any significant costs.

First of all, it is necessary to study the producer official website. As a rule, all manufacturers who cherish their reputation on the market post on their website reliable and truthful information about the products: the production method, the raw materials characteristics, the offered products characteristics, certificates and diplomas confirming the employee’s qualifications, the ways of control the finished product quality, etc. At the same time, you can analyze information about the manufacturer at other specialized portals — tender sites, groups in social networks, news sites (forums), etc.

You can also get reviews from other enterprises previously used the steel grinding balls by this manufacturer.

Next, you need to request all the accompanying documents — a quality certificate, the hardness reports over the entire cross-section of the grinding ball, the impact resistance reports, documents confirming the grinding media chemical composition, etc. You can request a reference list, also.

If the manufacturer has convinced you in quality of the offered grinding balls, then you need to request the grinding balls samples. You need to send the samples for complete analysis (the cross-section hardness, the chemical composition, the impact resistance) to a specialized laboratory with state certification for such research. As a last resort, it is possible to check the quality of the grinding balls using OTC’s own resources.

Performing these simple operations, you can determine how much the grinding media supplier is interesting to you and how much the information provided by him in the commercial proposal is true. And if you decide to purchase these grinding balls, you must at first to conduct an industrial test for determination «Are these grinding media suitable for your production?» and then use grinding balls on an ongoing basis.
