Taguchi-based experimental design technique has been a major research area for making systematic approaches to understand the complex process of ball mill process parameters influencing on the synthesis of ultrafine silica sand monolayer degradation. To determine an optimal setting, Taguchi coupled optimization technique has been applied with a novel approach as there is no previous work focusing on the synthesis of ultrafine silica sand taking in account the ball milling process parameters and Taguchi coupled optimization techniques. The high-grade silica was milled in planetary ball mill and the selected samples were passed through washing, crushing, dehydrating, meshing and drying operations. The samples were analyzed using Malvern Instruments for particle size distribution. The experiments were conducted as per Taguchis L9 orthogonal array. Process parameters were analyzed using the signal-to-noise ratio based on the-smaller-the-better approach. To minimize the effect of uncontrollable variables, The ANOVA results determined the significance of the influential controllable variables so that the variability in the response is small. Optimization results confirmed that the balls to powder weight ratio were the most influential process parameter. The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum speed of the ball mill is 105rpm. Using SEM characterization, the improved particles of silica sand presented a spherical shape with a cluster. Using TEM of different structures of the ultrafine silica sand containing asymmetrical characteristics of particles confirmed the solid form of the ultrafine silica sand.

Natural MoS2 is ball-milled.Electrochemistry and catalytic properties of ball-milled MoS2 are investigated.Ball-milling process enhances both the electrochemistry and the catalytic behavior of natural MoS2.
MoS2 nanosheets of one to few layer thickness present novel electronic and enhanced catalytic properties with respect to the bulk material. Here we show that a simple and highly scalable ball-milling procedure can lead to significant improvements of the electrochemical and catalytic properties of the bulk natural MoS2. We characterized the material before and after the milling process by means of scanning electron microscopy, energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy in order to evaluate morphological and chemical features. We investigated the electrochemical properties by means of voltammetry techniques to monitor the electron transfer with [Fe(CN)6]4/3 redox probe and the catalytic properties by monitoring the electrochemical hydrogen evolution reaction (HER). A significant overpotential lowering of about 210mV is obtained for the HER by the ball-milled material when compared to bulk materials. This has a huge potential for the lowering of the energy consumption during hydrogen evolution. Ball-milling offers highly scalable dry method for large scale production of electrocatalyst with enhanced properties.
BM500 is a versatile laboratory ball mill intended for the milling and homogenization of a broad variety of samples ranging from soft, fibrous to hard and brittle materials. With a simplified handling principle it enables the quick processing of dry, wet, and even cryogenic milling procedures. As the all-rounder suitable for any application segment, BM500 quickly manages routine as well as scientific applications. Depending on your material and preparation settings a final particle size of around 1 m is achievable. (Grinding jars and balls need to be ordered separately)
One rotary-push button is the only tool you have to operate to set all process parameters needed for appropriate grinding and homogenization. This easy and intuitive concept enables quick handling and minimizes errors. It is therefore beneficial for daily routine work.
BM500 operates in simultaneous mode, which enables you to treat two independent subsamples in exactly the same way. This is advantageous for several reasons such as grinding a higher amount of sample at once or having one sample batch left as a backup and control sample. The largest cup volume handled by BM500 is 2 x 50 mL.
The broad range of accessories for BM500 enables you to mill almost any sample material to the fineness you need for your subsequent analysis. Especially when analyzing the powder itself sufficient homogeneity guarantees that all components are detected correctly.
BM500 is an all-rounder for milling and grinding and therefore suitable for samples ranging from metals and rocks to food, biological and environmental materials. The shape of the sample does not matter, BM500 easily manages grains, pellets and fibers as well as voluminous samples like wool, grass, and leaves.
For elastic materials as well as sensitive samples such as those with volatile components, the cryogenic application is available to enable grinding at all or to avoid the degradation or loss of certain components.

Total hydrolysis was obtained in 5 minutes for Mg alloy milled with graphite followed by milling with AlCl3 under Ar. Excellent hydrolysis performances are obtained for Mg alloy milled with graphite under Ar. The scale-up of laboratory milling strategy to industrial scale has been established.
Ball milling strategy is of prime importance on the hydrolysis performance of Mg alloy waste. The effect of milling device (e.g. Fritsch Pulverisette 6 (P6) and Australian Uni-Ball-II (UB)), milling atmosphere (H2 and Ar), milling time, nature of the additives graphite and AlCl3 and synergetic effect by chronological or simultaneous addition were examined. An equivalence between both mills was established and it was shown that the process with the UB is 10 times longer than that with the P6 to acquire a similar material. Mg alloy milled without additives in the P6 under Ar for 10h improves the hydrolysis performance. Using a single additive, the best hydrolysis performances are obtained with graphite (yield of 95% of total capacity reached in 5minutes) due to the formation of a protective graphite layer. By incorporating both additives sequentially, the best material, from the hydrogen production point of view, was Mg alloy milled with G for 2h and then with AlCl3 for 2 extra hours (full hydrolysis in 5minutes). Mg alloy milled with the P6 were compared to those milled with the UB. Mg alloy milled with graphite or with sequential addition of G and AlCl3 under Ar generated more than 90% of their total capacity. Our results confirm that laboratory-milling strategy can be scaled-up to industrial scale.

Biochar with particle size of 212nm was obtained at optimized milling conditions.Keeping biochar at80C before milling reduced the size to around 60nm.The surface area of nanobiochar increased 15 times compared to the raw biochar.The produced nanobiochar can be used for removal of carbamazepine from wastewater.
Environmental considerations along with the technological challenges have led to search for green and energy-efficient processes for advanced nanostructured materials. In this study, nanobiochar was produced from pine wood biochar using a planetary ball mill. A central composite experimental design and response surface methodology was employed to optimize the ball milling parameters including time, rotational speed and ball to powder mass ratio to obtain nanoparticles in short time and at lower energy consumption. ANOVA results showed that the linear and quadratic effect estimates of time and the interaction effect of time and rotational speed were significant contributors to the size of particles during milling (p<0.05). Based on the developed statistical model, the optimum conditions for obtaining the smallest particles, around 60nm, were found to be 1.6h, 575rpm and 4.5g/g. However, the size measurements indicated that particles had a great tendency to agglomerate. Further study showed that the conditioning of biochar at cryogenic temperatures prior to milling inhibits the agglomeration of nanoparticles which is essential in industrial processes. The adsorption test proved that the nanobiochar produced using green method is promising in the removal of micropollutants from aqueous media by removing up to 95% of carbamazepine from water. At the optimum milling parameters and conditioning for 24hat80C, nanobiochar with the average size of around 60nm was obtained. The produced nanobiochar was characterized by Brunauer-Emmett-Teller (BET) gas porosimetry, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Also, physical and chemical properties, such as water holding capacity, organic matter, oxidation-reduction potential (ORP), elemental composition, polycyclic aromatic hydrocarbons (PAHs) and heavy metals were analyzed.
