· Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, .
Wiki says "A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics." Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.
ME EN 7960 – Precision Machine Design – Ball Screw Calculations 43 Based on Load • A ball screw transforms rotational motion into translational motion. As a result, the shaft is subject to loads: – Thrust force (the sum of all external forces such as machining load, gravity, friction, inertial forces, etc.).
