“…The changes in the mass percentages of the elemental components could be due to the effects of ball milling conditions, i.e., milling time and ball-sample ratio. One study illustrated similar results, where the changes in mass percentage occurred with altering milling conditions (Supriyono et al 2018). It was noted that carbon was also the most dominant element presence in their study, and the reduced particle size did increase carbon mass percentage indicated by their EDS experimental result.…”

Biochar was synthesized from biomass (jatropha seeds) through a low microwave pyrolysis temperature of 180 °C with microwave power of 2kW. A ball milling process reduced the jatropha seed biochar size and converted it into micro-nano carbon biofiller. After ball milling, the biochar size was reduced from 1 to 3 mm to the 10 µm to 600 nm range, which is around a 90% reduction in size. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and Brunauer-Emmett-Teller (BET) analysis were used to determine the jatropha seed biofillers properties with respect to the ball milling processes. BET results revealed increasing surface area from 0.10 to 3.67 m2/g, and EDS results revealed the elemental composition of the jatropha seed biofillers. The carbon mass percentage increased from 72.6 to 81.2%. Both results were after ball milling for 30 hours. The FTIR results revealed an increase in transmittance intensity and some reduction in peaks after ball milling. Production of micro-nano carbon fillers from microwave pyrolysis jatropha seeds biochar are applicable as reinforcement fillers for high strength composite material fabrications. Scanning electron microscopy, EDS, FTIR, and BET analysis results indicated size reduction of the biochar with increased carbon content from 72.6 to 81.2% as surface area increased from 0.10 to 3.67 m2/g after 30 hours of ball milling.

“…It was noted that carbon was also the most dominant element presence in their study, and the reduced particle size did increase carbon mass percentage indicated by their EDS experimental result. The results of work by Supriyono et al (2018) showed the smallest biochar particle size to be 274 nm, with a carbon mass percentage of 93.0%.…”

“…The resulting particles are between 250-475 μm in size [13]. Supriyono et al [14,15] developed a new design of ball milling machine and studied the effect of cycle number and ball diameter on the final particle size and morphology of bamboo charcoal. The final particle sizes are in the range of 250 nm to 500 nm.…”

The aim of this work is to characterize particle of bamboo leaves charcoal produced by ball milling process. The characterization parameter are the particle size and the morphology of the particle. The milling process was completed in a cylinder vial made from stainless steel. The milling element was a steel ball. The dimension of the cylinder vial was 120 mm length and 1 inch diameter, while the ball diameter was 0.25 inch. The charcoal was crushed manually then sieved with a filter size of 200 meshes. The particles passing the filter were then put together with the milling balls into cylinder vial. The cylinder vial was shaken to have ball collision for the size reduction. The shaker machine was operated at 1000 rpm for 2 million cycles. The empty space in the vial was varied for 1/2, 1/3, 1/4 and 1/5 empty space of vial volume. Further work is done to see the effect of the machine speed to the characteristics of particles. The machine is operated at 800 rpm, 900 rpm, 1100 rpm for 1/5 empty space and 0.25 inch ball diameter. Particle size analyzer (PSA) was used to measure average particle size, while Scanning electron microscope (SEM) and Energy Dispersive X-ray (EDX) were employed to see the particle morphology and the content of elements in the bamboo leaf charcoal. The results showed that the average size of particles is in the range of 300 nm to 600 nm. There is no certain relationship between final particle size and percentage of vial volume empty space. The SEM results showed that the particle shape is irregular as a result of fracture due to collision. The most dominant element is carbon which is more than 60% and the second is silicon dioxide (silica) which is more the 20%.

“…This research carried out a characterization of bamboo tutul charcoal nanoparticles resulted fromhigh energy ball milling (HEBM) shaker type the same as the work done by Supriyono et al [8]. However, since the milling process is conducted in a vial, the empty space of the vial for the ball movement will determine the final size of the particles.…”

The objective of this study is to characterize bamboo tutulcharcoal particles produced by High Energy Ball Milling (HBEM)shaker type.The HEBM process was conducted in the stainless steel vialsfor 2 million cycles at 900 motor RPM. The ball milling diameter was 1/4 inch made from steel.Therefore, perhaps the final particle sizewill be determined byempty space of the vial for the movement of the balls. In this study, the empty space is varied for 1/2, 1/3, 1/4, and 1/5 of vial volume. Particle Size Analyzer (PSA) is used to have the particle sizes and SEM-EDX is used to have surface morphology of the particle. The average final particle sizes are 547.8 nm, 522.9 nm, 422.7 nm, and 739.4 nm for 1/2, 1/3, 1/4, and 1/5 empty space of vial respectively. The surface morphologies of the particles are determined by fracture mechanism as they can be seen on the SEM results. Based on the results, it can be said that there is no correlation between the particle size and the empty space of the vial. As long as there is space for movement of the milling balls, the collision occurs and the reduction of the particle also happens.
