Abstract:

Vibrating screen is the most commonly used sieving machinery, how to improve its sieving performance is a major issue during the design and application. Discrete element method (DEM) was employed here to analyze and simulate the sieving process, and the influence of the various sieving parameters on sieving efficiency were studied. The curve of relationship between the sieving parameters and sieving efficiency was established. Contrasted with traditional methods, DEM has great superiority on the sieving study.

Abstract:

The problems of high falsesieving rate and low productivity are encountered while sieving shelled buckwheat with traditional round plate sieve. This paper presents a design idea for improving the sieving effect by changing the plate structure. The improved designs consist of a round plate sieve with larger percentage of sieving area than the traditional round plate sieve and a triangular plate sieve with the approximately same geometry as shelled buckwheat grains. Tests are conducted to compare the sieving performance of traditional round plate sieve with the newly designed round plate sieve w

Abstract:

Continuous hemofiltration was conducted in vitro to identify parameters that affect drug transport across hemofilter membranes. The removal of seven drugs with different molecular weights and protein binding characteristics was assessed. Sieving coefficients were determined with both blood and saline using polysulfone, polyacrylonitrile and polyamide membranes. Drug sieving coefficients obtained with saline were generally higher than those obtained with blood. Molecular weights of the drugs did not correlate with the magnitude of drug sieving. Sieving coefficients in blood were also predicted

Abstract:

Sieving grains is a fundamental process in the agricultural and food industries and is crucial for enhancing cereal products' quality and safety. However, manual grain sieving results in drudgery, fatigue, and time wastage during the processing. The importance of sieving grains spans several dimensions, including improving grain purity by removing foreign materials and impurities such as stones, dust, and chaff. This process also ensures uniformity in grain size, which is vital for consistent cooking and processing characteristics, thereby enhancing product quality and consumer satisfaction. A

Abstract:

Lattice sieving is asymptotically the fastest approach for solving the shortest vector problem (SVP) on Euclidean lattices. All known sieving algorithms for solving the SVP require space which (heuristically) grows as $2^{0.2075n+o(n)}$, where $n$ is the lattice dimension. In high dimensions, the memory requirement becomes a limiting factor for running these algorithms, making them uncompetitive with enumeration algorithms, despite their superior asymptotic time complexity.We generalize sieving algorithms to solve SVP with less memory. We consider reductions of tuples of vectors rather than pa

Lump breaking and sieving is commonly done by hand to remove ungrated and tread like cassava. A faster method of lump breaking and sieving in gari production necessitated the need for the designing of the motorized gari sieving (sifting) machine, aimed at reducing or completely eliminating all problems associated with sieving of gari.

The percentage of soil material > 0.84 mm obtained by dry sieving is commonly used as an index of the wind erodibility of soils.

An equation was fitted to soil sieving data from a modified rapid rotary sieve. It successfully evaluated aggregate attrition during sieving for 397 out of 404 samples representing a wide variety of textures.

Abstract:

The vibrating screen is used for sweet corn pre-processing. The machine is formed by the electric motor, the transmission system module, the sieving module as well as the rack, in total four parts. With enough tests, the machine is compact in structure and works smoothly and can avoid too much colliding. Also, it’s good at sieving and has a high efficiency and can satisfy the requirement of sieving sweet corn.

Abstract:

In order to effectively predict the sieving efficiency of a vibrating screen, experiments to investigate the sieving efficiency were carried out. Relation between sieving efficiency and other working parameters in a vibrating screen such as mesh aperture size, screen length, inclination angle, vibration amplitude, and vibration frequency was analyzed. Based on the experiments, least square support vector machine (LS-SVM) was established to predict the sieving efficiency, and adaptive genetic algorithm and cross-validation algorithm were used to optimize the parameters in LS-SVM.

Abstract:

In a landscape where interest in prime sieving has waned and practitioners are few, we are still hoping for a domain renaissance, fueled by a resurgence of interest and a fresh wave of innovation. Building upon years of extensive research and experimentation, this article aims to contribute by presenting a heterogeneous compilation of generic tweaks and boosters aimed at revitalizing prime sieving methodologies. Drawing from a wealth of resurfaced knowledge and refined sieving algorithms, techniques, and optimizations, we unveil a diverse array of strategies designed to elevate the efficiency,

Abstract:

This study performs a methodical experiment on adaptation and unification of soil dry sieving analysis. The analysis is based on the Savvinov dry sieving method that uses 0.5-1.5 kg air-dried soil samples which are passed through the 10, 7, 5, 3, 2, 1, 0.5, 0.25 mm sieves. The studied soils are silt loam Eutric Retisol and Haplic Chernozem. From each object, 50 kg of fresh soil was sampled from the plow layer (lm2area). Air-dried soil subsamples of 500 ± 0.5 g were used for analysis, clods bigger than 50 mm were gently crushed by pestle with rubber tip. The sieving parameters were the followin

Abstract:

According to the self-synchronous theory with two vibrating electric motors, a translation elliptic shaker is designed, and its finite element model for the sieving box is established. The dynamic behavior analysis of the sieving box is reached with CATIA software. The natural frequencies and modal oscillation modes of the sieving box are calculated, and the stress and deformation distribution in every part of the sieving box under rated load are obtained. All shows that, its structure design is reasonable. Under the designed working conditions, the maximum principal stress of the side boards

Abstract:

Clarifying the mechanism for the gas transportation in the emerging 2D materials-based membranes plays an important role on the design and performance optimization. In this work, the corresponding studies were conducted experimentally and theoretically. To this end, we measured the gas permeances of hydrogen and nitrogen from their mixture through the supported MXene lamellar membrane. Knudsen diffusion and molecular sieving through straight and tortuous nanochannels were proposed to elucidate the gas transport mechanism. The average pore diameter of 5.05 Å in straight nanochannels was calcula

Abstract:

In order to improve the cleaning effect of the castor shelling mixture, an air-sieve castor cleaning device was developed. The structure of the cleaning device was optimized by experiment and simulation based on the discrete element method. The results show that the sieving efficiency of the square distribution is 98.23% and the loss rate is 2.39%, both of which are better than the triangular distribution. The sieving efficiency in the condition of a 14 mm sieve hole diameter is 98.23%. For the conditions of 15 mm and 16 mm sieve hole diameters, the sieving efficiencies are 96.64% and 96.69%,
