Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents. SAG mills generate higher levels of impact reduction and ...

Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and ...
To prevent your motor from burning out I would recommend 2-3lb's lead and 150-200g composition per jar. I personally use just over 2Lb's lead and 200g composition with a 1" O.D. drive roller in my 3Lb jars on these mills. PERFECT black powder in 20-23 hours. With 150g composition in the mill it's perfect in around 14 hours.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
A ball mill is a crucial piece of machinery used in grinding and mixing materials in various industries. It works by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. Ball mills are used extensively in the mining, construction, chemical, and pharmaceutical ...
