Planetary ball mill is a powerful tool, which has been used for milling various materials size reduction. The discrete element method (DEM) was to simulate the dynamics of particle processes in planetary mill. This work includes calibration DEM parameters using EDEM Altair 2021.2 software, provides both faster workflows and results. iterative input changed close correlation between simulation e...

The grinding process has become widely used to improve the fineness and performance of fly ash. However, most studies focus on particle size distribution ground ash, while morphology is also an important factor affect cement paste. This article aims at three different kinds ash from ball mill vertical mill, observed by scanning electron microscopy (SEM) calculate spherical destruction (the rati...

In this paper, the possibility of mechanical coating of aluminum with either Ni or SiC using planetary ball mill was studied. The Al substrate was fixed inside of the vial lid of a planetary ball mill filled with milling balls and starting powder. The phase analysis and crystallite size measurement of the coatings were carried out using X-ray diffraction (XRD) method. Scanning electron micro...

Among the anaerobic systems applied for the treatment of paper industry effluents, the IC (Internal Circulation) reactor is gaining a lot of interest. The reactor combines good biomass retention at the outlet with excellent mixing characteristics in the lower part of the reactor. This leads to smaller reactor volumes and less space requirements. Three examples of IC reactors at various recycle ...

This review is focused on the topical developments in synthesis of nanocomposites using simplest top-down approach, mechanochemical milling, and related aspects interfacial interactions. Milling constraints include time duration ball size, ball-to-sample content proportion, rotation speed, energy that took part a vital structure–property relationships composite Milled are being used different s...

in this article vanadium boride nanopowder was synthesized by mechanochemical reduction method in a high-energy ball mill. the synthesized powders were studied by x-ray diffraction (xrd), scanning electron microscopy (sem), xray map and transmission electron microscopy (tem). according to x-ray diffraction the product predominantly consists of vb phases after 100 min milling without further hea...

clarithromycin (cla), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. the aim of this investigation was to prepare cla nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (sls) and polyvinyl pyrrolidone (pvp) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. different weight rati...

Neuronal network flexibility enables animals to respond appropriately to changes in their internal and external states. We are using the isolated crab stomatogastric nervous system to determine how extrinsic inputs contribute to network flexibility. The stomatogastric system includes the well-characterized gastric mill (chewing) and pyloric (filtering of chewed food) motor circuits in the stoma...

The main factors that influence the quality of the raw meal during its production in a ball mill and storage in stock and homogenisation silos of continuous flow are investigated. A detailed simulation is used, incorporating all the key characteristics of the processes. The quality modules of the raw meal are controlled via robust PID controllers, optimized with the same simulator. The effect o...

Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill, Rolls Crusher and Ball Mill. The pulverised samples were sieved to obtain four particle size fractions and temperature-programmed combustion (TPC) was used for the evaluation of their combustion behaviour. In addition, three coals of different hardness and rank were mixed in various proportions...
