This paper compares Discrete Element Model predictions for power and variations in impact and abrasion (low angle impact) breakage with power and grinding rate predictions from the more "traditional" JKMRC models. The DEM predictions are based on measured mill load sizings from a large industrial SAG mill at two operating conditions. The load sizings can also be predicted with reasonable accura...

the aim of this research work was to investigate on the ball filling estimation of miduk semi-autogenous (sag) mill via an utilized method. miduk copper concentrator is located in kerman province, iran, and its size reduction stage includes one gyratory crusher which feeds one sag mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). after sag mill, a tromm...

A new, ligand- and solvent-free method for the Huisgen 1,3-dipolar cycloaddition (click reaction) was developed using a planetary ball mill. Besides various alkynes and azides, a propargyl functionalized polymer was converted by mill clicking. Moreover, it was possible to carry out a click polymerization in a ball mill.

Two fungi (unidentified) were isolated from soil and marine environments. These isolates were used for bioremediation of pulp and paper mill effluent at the laboratory scale. The treatment resulted in the reduction of color, lignin, and COD of the effluent in the order of 78.6%, 79.0%, and 89.4% in 21 days. A major part of reductions in these parameters occurred within 5 days of the treatment, ...

In this experimental work the ozone action on the depuration of olive oil mill wastewater is studied for different operational conditions based on an actual industrial treatment plant. It was verified that the application of a Mn-Ce-O catalyst prepared at the laboratory, with a Mn/Ce molar proportion of 70/30, enhances the depuration efficiency and the effluent biodegradability. Ozonation opera...

In this survey, we review work in machine learning on methods for handling data sets containing large amounts of irrelevant information. We focus on two key issues: the problem of selecting relevant features, and the problem of selecting relevant examples. We describe the advances that have been made on these topics in both empirical and theoretical work in machine learning, and we present a ge...

Brought to you by Nebraska corn producers through their corn checkoff dollars— expanding demand for Nebraska corn and value-added products. INTRODUCTION Across the United States, ethanol production continues to expand with monthly production records being set.With the continued expansion in production, co-products have emerged as excellent feed sources for livestock. For purposes of this manual...
