The significant costs insert on mineral processes due to mill liner wear including the labor costs, price of material and shut down periods. Therefore, the study of this phenomenon is economically important to optimize the mill operating conditions and liner profile design to decrease the wear rate. There is no appropriate and applicable research on impact wear evaluation of mill liners. In the...

simulation of grinding circuits has being performed from 30 years ago and is also to be more complete and powerful approach with improvement of mathematical models which simulate various processing units/machines. the modeling and simulation of various mineral processing circuits are presently performed. in order to simulate the present grinding circuits of esfordi phosphate processing plant, a...

objective:  unaccustomed and intense eccentric exercise is a common cause of delayed-onset muscle soreness (doms). there are multiple remedies for the treatment of doms, but its clinical and laboratory pieces of evidence are scarce. currently, the treatments proposed for doms are numerous and include pharmaceuticals, herbal remedies, stretching, massage, nutritional supplements, and other alter...

The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

A MOP has five key steps: team formation; baseline analysis; benchmarking; project definition; implementation, monitoring and feedback. In the MOP approach, technical and business intellect is substituted for capital and equipment. Baseline analysis provides the current performance, variation of key production and process elements, and provides the data for cause and effect analysis. A MOP look...

There’s an old saying in Washington DC — making laws is like making sausage; you’re better off not knowing the details. Well, that same spirit often applies to the coverage of science news. The focus is on the succulent final product rather than the process required to get there. But science journalists have found the need to take a break from that approach with one big biology story: the tale ...

Rhythmic motor patterns, which underlie behaviors such as mastication, respiration and locomotion, are generated by specialized neural circuits called central pattern generators (CPGs). Although CPGs can generate their rhythmic motor output in the absence of rhythmic input, these motor patterns are modified by rhythmic sensory feedback in vivo. Furthermore, although the importance of sensory fe...

An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...
