How Many Types of Ball Mill? - JXSC Machine
1. Short-cylinder ball mill: The length (L) of the cylinder is less than twice the diameter (D) of the cylinder, that is, the ball mill with L ≤ 2D is a short-cylinder ball mill. Single-bin structure ball mill, which is mainly used for coarse grinding or primary grinding, has high efficiency. 2. Medium-long cylinder ball mill, that is L = 3D. 3.
Ball Mill Loading - Dry Milling - Paul O. Abbe
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

different types of ball mills are applicable for organic synthesis at 50 the laboratory scale: PBMs and vibration or mixer ball mills (MBMs). In case of PBMs the grinding media (in the present case milling balls) are accelerated due to rotation of the milling chamber which itself is mounted on a sun disc rotating in the opposite direction.

Ball Milling - an overview | ScienceDirect Topics
Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear …

Lead is safer because it's softer. At every impact the balls will deform, spreading the energy over a much larger surface. This also makes the mill more efficient as you don't need the huge pressures that ceramic balls will produce. The larger contact area of lead means that more material will be crushed for each impact.
