Opis:: W pracy przedstawiono analizę rozwiązań konstrukcyjnych współczesnych układów roboczych młynów nożowych, oraz dokonano oceny przyjętych rozwiązań w oparciu o relacje pomiędzy wydajnością rozdrabniania a zainstalowaną mocą silnika. Zaprezentowane analizy wskazały, że różnice w konstrukcji wirnika mają decydujący wpływ na przeznaczenie młyna nożowego.
In the paper the analysis of rotor construction of cutting mills is present The aim of investigations was to determine an influence of rotor constr tion on the relation between cutting mill capacity and driving power. ( tained results indicated that rotor construction differences had a decis influence on cutting mill functioning.

Opis:: The design of the grinding circuits and the control of the transferring load in the ore preparation plants are of great importance from a technical and economic point of view. The importance of the circulating load for grinding process is well known and stated in the literature. However, there are not many studies on the effect on the following processes. In this study, the effect of the circulating load on both the grinding capacity and the subsequent flotation process was investigated at laboratory scale. Copper ore was used in the experiments. The circulating load was adjusted by changing the residence time of the material in the mill. Then, flotation experiments were carried out with the materials obtained at different circuit loads. The results showed that the grinding capacity can be increased up to 180% by optimizing the circulating load and it will positively affect the flotation performance. It was observed that a concentrate with the highest recovery for the same Cu grade was obtained with CLR of 150 % when compared to flotation recoveries through various CLRs. It is suggested that the circulating load should not be evaluated only in terms of the grinding process, but also the subsequent processes should be considered. Future studies in this area may contribute to industrial applications.

Tematy:: autogenous mill

Opis:: The verification of the desired capacity increase in the grinding circuits is performed by simulation studies as they suggest accurate and fast alternatives compared to expensive and labor-intensive methods, particularly for the evaluation of situations that require investment. In this study, simulation was used to evaluate the alternatives that can be made to increase the capacity from 38.86 tph to 90 tph in a grinding circuit where copper slag is autogenously milled. The slag sample was characterized by drop weight and abrasion tests to describe the breakage in autogenous (AG) milling. The performances of the existing circuit and equipment were determined by a comprehensive sampling study, and modeling studies were carried out to form the basis of the simulations. Simulation scenarios were evaluated as investment free and investment requiring alternatives. In the investment free option changing fresh feed size distribution was examined however, capacity could be increased up to only 42 tph. In investment option, increasing the mill motor capacities was simulated and 90 tph target throughput was provided. This result was validated in the plant by replacement of mill motors of AG and pebble mill for 1000 kW and 750 kW, respectively.
