This study evaluated microstructural and crystallographic phase changes after grinding (G) and regeneration firing/anneling (R) of Y-TZP ceramics. Thirty five bars (LavaTM and Ice Zirkon) were divided: Y-TZP pre-sintered, control (C), regeneration firing (R), dry grinding (DG), dry grinding+regeneration firing (DGR), wet grinding (WG) and wet grinding+regeneration firing (WGR). Grinding was con...

In the Present study, attempt will be made to propose a new method for prediction of long-term essential creep of concrete utilizing some short-term creep tests under high temperature. To do so, regarding the similarities between essential creep of concrete and creep in viscoelastic materials, the time–temperature equivalence relation in viscoelastic materials is evaluated for concrete. This re...

High energy consumption in size reduction operations is one of the most significant issues concerning sustainability raw material beneficiation. Thus, process optimization should be done to reduce consumption. This study aimed investigate applicability artificial neural networks (ANNs) predict particle distributions (PSDs) mill products. PSD key sources information after milling since it signif...

Ceramic grinding, which in this paper is defined as a method of using ceramic materials grinding media, favored by many processing plants an emerging high-efficiency and energy-saving method. This investigates the effect slurry mass concentration on characteristics magnetite taking feed secondary ball mill for research object. The study results show that significantly affects magnetite, especia...

Automation of grinding of metalcastings is desirable for many reasons. The major reasons are dangerous working conditions, low productivity, and inconsistency in human operations. As an approach to the automating grinding process, a gantrydriven grinding machine is proposed to manipulate an industrial hand grinder and control the grinding force applied to the work piece. To increase the materia...

The mobile nylon bag technique (MNBT) may offer a simple, rapid means for assessing ileal AA digestibility of pig feed ingredients. In the present study, the effects of washing bags recovered from digesta, the amount and fineness of feeds, and feed trypsin inhibitor activity on apparent ileal digestibilities (AID) of CP and AA were determined with the MNBT. Twenty-four ileorectal anastomosed pi...

The efficiency of the process grinding meat and bone feed depends on a number design technological parameters grinder operation. One most significant issues at same time least studied one is influence cycles loading with working bodies grinders particle size finished feed. To study this issue, authors proposed method for modeling using stochastic B-model cumulative damage, which based an unders...

The high cost of ceramic components can be associated with complex and time-consuming postmachining, which is currently done by using abrasive machining processes. The IWF and Fraunhofer-IPK are undertaking research activities in the field of abrasive machining which aim at developing and optimizing technologies to expand the application field and to increase productivity of high-performance ma...

The purpose of this study was to investigate the effects of cereal type and feed processing on the prevalence of gastric lesions in pars oesophagea, stomach size, stomach content and firmness and performance in growing pigs. Data from 320 pigs were included in a 2 3 2 3 2 factorial experiment. The factors investigated were cereal type (barley or wheat), disintegration method (grinding or rollin...
