W technologicznych układach przeróbki surowców mineralnych, a zwłaszcza kruszyw, rozdrabnianie odgrywa kluczową rolę, zapewniając uzyskanie produktu o odpowiedniej granulacji. Operacje kruszenia są także energochłonne oraz charakteryzują się dużą uciążliwością dla środowiska, chociażby ze względu na znaczną emisję zapylenia oraz generowany hałas. W artykule poruszony został temat dotyczący hałasu powstającego podczas pracy kruszarek. Analizie zostały poddane wybrane typy kruszarek, zmierzono poziom hałasu oraz dokonano powiązania uzyskanych wartości ze skutecznością technologiczną urządzeń, określoną jako uzyskany stopień rozdrobnienia i wydajność. Wyniki badań pokazują, że różne urządzenia rozdrabniające charakteryzują się pod tym względem różną uciążliwością dla środowiska.

: The paper presents results of a comparative analysis of revenues of the Lubin, Polkowice-Sieroszowice and Rudna mines (KGHM Polska Miedź S.A). The criterion used for comparison is the Net Smelter Revenue formula (NSR) based on heuristic model of functional relationships between the concentration of metals in ore and copper concentrates, the operational efficiency, and the prices of concentrates and metals in the global markets. The calculations have been performed for the data coming from the mining practice. The NSR calculations show that the Lubin mine is nearly 2 times less profitable than the Rudna mine, yet if we compare Cu+Ag+Au grading to the best (Rudna) mine, that difference is only 1.6-fold. However, it must be noted here that the Rudna and Polkowice mines are much deeper than the Lubin mine, therefore the total profit from the mine are not as different as the NSR value.
本文介绍了对卢宾、波尔科维茨-谢罗绍维茨和鲁德纳矿区(KGHM Polska miedzosa)收入的比较分析结果。用于比较的标准是净冶炼厂收益公式(NSR)，该公式基于矿石和铜精矿中金属浓度、操作效率以及精矿和金属在全球市场上的价格之间的函数关系的启发式模型。对实际开采数据进行了计算。NSR计算表明，Lubin矿的利润比Rudna矿低近2倍，但如果我们将Cu+Ag+Au品位与最佳(Rudna)矿进行比较，差异仅为1.6倍。然而，这里必须指出的是，Rudna和Polkowice矿山比Lubin矿山深得多，因此矿山的总利润并不像NSR值那样不同。
