a ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
it is potentially faster than a ball mill to make black powder, or other compositions. they are also useful to powder small amounts of chemicals. it has the disadvantage that it is extremely labor intensive relative to a ball mill. cia method – this is done by rapidly precipitating out kno3 with cold alcohol in the presence of charcoal and sulfur.

midland man is right on, you need a good shop press to corn the powder to be able to measure the powder by volume when loading a muzzleloader, and a ball mill with lead round balls in it to mix the ingredients in. it's not hard to do and it's safe unless you get a spark into the powder, which cannot happen if you use the lead balls.
sag is an acronym for semi-autogenous grinding. sag mills are autogenous mills that also use grinding balls like a ball mill. a sag mill is usually a primary or first stage grinder. sag mills use a ball charge of 8 to 21%. the largest sag mill is 42' (12.8m) in diameter, powered by a 28 mw (38,000 hp) motor.

media samples (0%, 50% and 100% compost) were oven-dried for 2 d at 60 °c and ground to a powder with a ball mill prior to combustion (nelson and sommers, 1996). total c and n concentrations were determined by a cns analyzer (carlo-erba na-1500; bico, burbank, calif.). compost extracts (25 g; dry
using larger diameter balls or increasing the volume fraction of al 2 o 3 nanoparticles to 7.5% or higher allowed, synthesis of cu-al 2 o 3 nanocomposite powders with nanocrystalline cu matrix.cu and al 2 o 3 were used as starting powders and two milling routes were used: in route 1, the powder mixture was milled for 12 hours using 60 balls with a diameter of 12.5mm; and route 2 was route 1
ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. ball mills basically function like a mortar and pestle, but on a much larger scale.
the impact of mechanochemical transformation is driven by the amount of energy transferred during mechanical interaction between the sample particles and working media to alter the chemical reactivity of the sample. 107 planetary ball mill and mixer (shaker) mills are the two main instruments used for this process and for an in-depth description of mechanical milling we refer the reader to the

the optimal ratio of large to small was determined by 1) feed size, in which a larger feed size required a greater proportion of large-diameter balls; 2) product size distribution, in that if a finer product size was needed, a greater proportion of small balls was required; and 3) mill diameter, in which a larger mill required a greater ratio of small balls.
got a quick question for you guys that make your own powder. what i've got is i accidentally got my ratio wrong. doh!!! found this out because my finished product burned extremely dirty. and i know what i did wrong. i use dextrin to bind my powder together. my question is if i mill the powder again will the dextrin already in the mix dissolve when i re-damp the powder to push it through a
when a tinted lip balm is desired, pigments typically are not added as pure powders. they are separately milled in a ball mill together with a wetting agent such as castor oil until their dimensions are below 15–30 μm. the entrapped air is easily released under slow mixing; therefore, this process is usually not conducted under a vacuum.
lead media is used to mill black powders, rocket fuels and charcoal. this same approach can be used to make milling jars of 1 gallon capacity by using 6 inch pvc pipe and fittings. the drawback is that a jar of this size will require 30 pounds of lead milling media.
process - mix the ingredients by weight (75% potassium nitrate, 15% charcoal, 10% sulphur), ball mill with lead balls for at least 24 hours, dampen, screen, and dry. this makes suitable pulverone for drivers, etc.

during milling, the porcelain balls pulverized the materials into an incredibly fine powder. ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. ball mills basically function like a mortar and pestle, but on a much larger scale.
in addition, the particle size distribution showed that median particle size was 49.20 µm for normal green tea, 15.01 µm for the leaves powdered with the ceramic mill, 23.03 µm for those treated with the ball mill, and 31.85 µm for those processed with the mixer ( figure 2 b). figure 2.
pour all powder into mill jar with media already in jar. seal mill jar. #2: run mill 3-6 hrs. #3: empty mill jar into strainer over newspaper or bucket, sift out lead, place back into jar #4: powder is now 'mill dust' black powder, it can be granulated next... #5: wet powder with water and about 10% alcohol to aid absorption into dry powder. mix by hand or spoon until it's a clay like consistency.
