During the operation of a grinding circuit (GC) in mineral processing plant main purpose control and optimal is to product quality index, namely particle size, into its technically desired ranges. Moreover, production rate needs be maximized. However, due complex dynamic characteristics between above two indices loops, such objectives are difficult achieve using existing methods. The complexity reflected by existence process heavy nonlinearities, strong coupling large time variations. As...
Transparent-photochromic materials have garnered significant attention for their applications in optical information storage and anti-counterfeiting, which necessitate excellent transparency high contrast. Herein, x mol% Sr2+ 1 mol%...
Sr/Er was codoped in KNN ceramics to induce the coexistence of O and T phases, resulting improving optical transparency, maintaining moderate ferroelectricity, inducing excellent PC behavior fluorescence temperature sensing performance.
This paper attempts to disclose the law of shock wave formation and propagation time history impact pressure on blasthole wall during blasting with radial uncoupled charge No. 2 rock emulsion explosive (No. REE). For this purpose, author carried out an analysis by tube theory, as well model experiments concrete thick-walled cylinders, then investigated relationship between peak uncoupling coefficient (RUC) air space. The research results show that, when RUC fell within range K = 1.50–3.50,...
Abstract The compatibilization of polypropylene (PP)/nylon 6 (PA6) blends with a new PP solid‐phase graft copolymer (gPP) was systematically studied. gPP improved the compatibility PP/PA6 efficiently. Because reaction between reactive groups and NH 2 end PA6, PP‐ g ‐PA6 formed as compatibilizer in vicinity interfaces during melting extrusion PA6. tensile strength impact compatibilized obviously increased comparison those mechanical blends, amount content third monomer preparation affected...
This study proposes a hybrid structural design concept of polyurethane foam-filled magnesium alloy AZ31B rectangular thin-walled beams which serve as energy absorbing components in automotive applications. Uniaxial tensile and compressive tests, fracture tests were performed to investigate the material mechanical properties. Dynamic three-point bending deformation/fracture modes absorption capacity for beams, compare these properties with those mild steel DC04 beams. Different filled...
This paper aims at providing a sound theoretical solution to auxiliary central hole and the cutting parameters. For this purpose, forming mechanism of V‐cut cavity for blasting was performed based on hypothetical rock breaking blasting. A increasing critical depth center cuthole criteria diameter various types cutholes when attributes, explosive properties, dip angle are constant proposed.

The double-hat-shaped magnesium tube was difficult to use in actual applications due its frangible material property. Magnesium alloy and traditional steel were integrated into a new hybrid thin-walled improve vehicle crashworthiness. Two classes of tubes examined, namely Hybrid-I (steel top hat bottom hat) Hybrid-II (magnesium hat). energy absorption characteristics crashworthiness optimization the structures investigated under three-point bending conditions through experiments simulations....
Quasi-static/dynamic three-point bending tests were conducted to assess the crash performance of magnesium alloy AZ31B extruded and sheet tubes at German Aerospace Centre (DLR) – Institute Vehicle Concepts in Stuttgart. Different foam-filled beams with a variation foam density thickness fabricated through several manufacturing processes: cold bending, tungsten inert gas welding, cathodic dip painting polyurethane injection. The experimental results compared those from mild steel DC04 tubes....
The quality of rubber machinery equipment does not only depend on its machinofacture, but also automation control level. Twin screw extruder is the important auxiliary engine internal mixer. Due to intermittent working mixer, speed twin has nonlinear and time invariance problems. According system's characteristics, this paper proposed adopting fuzzy improve system with view advancing extruder's production efficiency service life. It built traditional adopted control. can be seen from...
As the lightest structural metal, magnesium alloys have been attractive to reduce vehicle weight and emissions by lightweight design in automotive industry. Structural crashworthiness is not a physical property itself, but correlates with material’s ductility design. Magnesium known be material lower failure strain than other metallic materials. Therefore use of crash-related areas more challenging compared steel aluminum.In structures bending load, as case bumper or sill, crash properties...
Oil well cement was added as an admixture to the waterborne epoxy resin cementing fluid form a resin-cement slurry system, and its properties were discussed in depth. It found that mechanical of stone best when dosage oil 10%. And measurements X-ray diffraction (XRD) Fourier transform infrared spectroscopy (FTIR) showed addition did not affect curing resin, hydration process products. According data from mercury-in-pressure porosity (MIP) method scanning electron microscopy (SEM), it...
