The authors of the article consider properties grain as an expensive and very complex raw material. With varietal milling wheat in cost flour, main share falls on purchase - up to 80 ... 85%. Therefore, when organizing maintaining grinding, it is required optimize modes processes technology both preparatory grinding sections mill, moreover, based choice objective criteria for efficiency process...

the main task of drilling the formation by the bit is done via scraping, crushing and grinding. discharging the fluid from the bit nozzles is done with high pressure which assists to break the rocks. different parameters affect the bit selection and design for each drilling formation, but the most important one is drillability that depends on hardness of the formation. in this paper, the design...

The processing of woody biomass waste piles for use as fuel instead of burning them was 11 investigated. At each landing slash pile location, a 132 kW grapple excavator was used to transfer 12 the waste piles into a 522 kW horizontal grinder. Economies of scale could be expected when 13 grinding a larger pile, although the efficiency of the loading operation might be diminished. Here, 14 three ...

The specification for the total thickness variation (TTV) of the device layers on thick-film silicon on insulator (SOI) wafers tighten for future applications. Therefore, the bulk removal polishing process of current technology after grinding cannot meet the demands in terms of flatness. The currently required amount of material removal for polishing out the induced sub surface damage (SSD) of ...

This study evaluated the effect of feed form and grinding intensity of the pig diet and the interaction between both on the particulate matter (PM) concentrations inside a pig nursery and the growth performances of weanling pigs. Four diets were compared: finely ground meal, coarsely ground meal, finely ground pellets, and coarsely ground pellets. Four weaning rounds with 144 pigs per weaning r...

This research is to investigate the dynamic characteristics of the grinding process. A kind of robust grinding wheel reciprocating arrangement is schemed out, which realizes the precise point-grinding machining. The grinding wheel reciprocating movement is driven by a linear motor to replace the traditional crank or hydraulic pressure drive device. Based on the time series method, the modal exp...

Industry worldwide has been marked by intense competition in recent years, placing companies under ever increasing pressure to improve the efficiency of their product processes. In addition to efficiency, precision is an extremely important factor, allowing companies to maintain standards and procedures aligned with international standards. One of the finishing processes most widely utilized fo...
