the major problem in material removal process specially grinding is heat generation during the process and thus residual stress on the surface of product. therefore, optimization of high efficiency deep grinding (hedg) process is the main goal of this study in order to reduce heat and residual stress and also increase strength and surface hardness of aisi1045 steel by optimization of the proces...

due to the importance of material classification issue in grinding circuits, the ‎performance of primary and secondary hydrocyclones in grinding circuit of esfordi ‎phosphate plant was investigated by sampling within 7 days from feed, overflow, and ‎underflow‎ of these hydrocyclones. at first, the d80 of above streams samples were calculated by ‎the screening analysis. the results showed ‎that ...

Twenty eight Ossimi male lambs, with an average live body weight 4.75 kg and 7 days age were randomly assigned to two feeding groups each of 14 animals to study the effect of pre-weaning diet on lamb's rumen development. Both the two groups suckled their dams until being weaned at 12 weeks of age (natural weaning). The first group depended completely on dam's milk as a solely available feed (co...

In order to obtain the necessary shape of long panels and sheaths, aircraft industry successfully uses a complex technology shaping. Grinding, as an operation in technological process, is provided after shot-peen forming before hardening. It designed ensure that roughness final aerodynamic surface meet requirements established by drawing part. To implement this technology, special installation ...

The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to mea...

The majority of fuel ethanol in the United States is produced by using the dry-grind corn ethanol process. The corn oil that is contained in the coproduct, distillers' dried grains with solubles (DDGS), can be recovered for use as a biodiesel feedstock. Oil removal will also improve the feed quality of DDGS. The most economical way to remove oil is considered to be at the centrifugation step fo...

Price will dictate inclusion rates, but increasing availability of this grain legume is resulting in pricing that is competitive with other feeds. In creep feeds, 30 percent to 50 percent field peas appears to be optimum for animal performance. Commercial feed manufacturers are including peas in a number of commercial products for their nutrient density, palatability and competitive price, and ...

These results support the earlier findings by Dr. Bill Kunkle and his research involving limitcreep supplements based on cottonseed meal and salt mixtures. Calf performance responses, as measured by the added gain realized by creep supplementation, are highly variable and cannot always be described by amounts of creep feed consumed. This variability has large and direct impacts on the cost effe...

The paper presents the application of a fuzzy predictive control technique to optimize the operation of a mineral grinding plant, specifically in order to maximize the ore feed rate and to follow a predetermined particle size set-point. The proposed predictive control uses linear multivariable models and a fuzzy characterization of goals and constraints to generate the appropriate values for ma...
