Dry grinding of CuO with sulfur in a ball mill was conducted to increase floatability of the copper oxide. It was noted that increasing grinding time was the main effective parameter on CuO flotation efficiency.
Subsequently, a vibration mill was used to prepare sulphur carbon composites at lower stress energies than during the process in a planetary ball mill, enabling the preservation of the pores with simultaneous homogenization of the product for further processing, and showing high potential for scale-up.
These ingredients are processed in a ball mill, basically a spinning drum with non-sparking ceramic or lead balls. The more time left in the mill, the more "explosive" the powder will be. One main reason to ball mill as opposed to other methods is because it presses sulfur and potassium nitrate into the porous charcoal. Tutorial [] Composition
Sulfur: 20 grams: How Does ball mill Work? Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.
9.9. A SAG mill of diameter 9.0 m and width 6.0 m was charged to 40% of the mill volume with ore of SG 3.2 when the porosity was 38%.With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to …
The image above shows a pulverizing drum (ball mill) from the nineteenth century. This particular model was in common use in France. The ingredient to be ground was put in, along with an equal weight of brass balls and then then drum was rotated at about 20 revolutions per minute. ... Usually, sulfur and saltpeter were ground together initially ...
as ball mills to crush the charcoal and sulfur. A ball mill is basically a large rotating drum filled with charcoal, sulfur and a crushing agent, such as lead balls or heavy stones. The mill is rotated at high speed for up to 48 hours or longer. The result is …
In making black powder, I've found that a material charge of 15 ounces of potassium nitrate, 3 ounces of airfloat charcoal, and 2 ounces of sulfur produces the most efficient quantity of BP mill dust. The density of the mill dust, and therefore the volume it occupies, will vary a bit with the density of the charcoal used.

Surface defects of ZnO nanoparticles were induced via mechanical stressing using a Turbula shaker mixer and a planetary ball mill, and the possibilities for surface modification and functionalization of the ZnO nanoparticles were exemplified by sulfur doping of activated ZnO. Raman spectroscopy reveals that the formation of oxygen vacancies (V O) does not only …
Thus, the activated samples were thoroughly mixed with an excess of sulfur (15 mass eq.) in a ball mill and transferred into an argon purged tubular furnace. In order to impregnate the samples with sulfur, the samples were kept at 155 °C given the fact that sulfur has its lowest viscosity at that temperature.

and sulfur were mixed with ball-milling in an open atmosphere at a speed of 500 rpm and different times (590, 1725, and 2880 minutes) [13]. 3.2. Melt-Diffusion Melt-diffusion is a method that utilizes the physical properties of sulfur itself, which has a melting point of ~ 1150C [10].
The influence of adding sulfur as mechanochemical sulfidization agent into ball mill without any other additive was studied on the flotation of mixed copper ore using different weight ratios including 0.2 wt%, 0.5 wt%, 1 wt%, 2 wt%, 5 wt%, 8 wt% and 12 wt%, and then was compared with sulfidization flotation as shown in Fig. 2.

Open the lid to your Ball Mill and add the following: 150 grams of Potassium Nitrate, 30 grams of Charcoal Powder, and 20 grams of Sulfur ( if your lead balls are not already in the tumbling barrel, go ahead and put them in now ). Remember that ONLY lead balls can be used because they are completely non-sparking.
