The conical mill, or what is more commonly known as the Hardinge mill, is one of those inventions which, if not fathered by actual necessity, was at least induced by the desire to get better results from the energy expended in operating the older types of pebblemills in my metallurgical work.
Ball mills are different. The grinding media is unfixed steel ball, etc., which produces larger sized powder than grinding mill. the size of the discharged product can mainly be adjusted between 40250 mesh. If the size of discharged product is uneven, it is needed to equip a powder separating machine.

Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.
A tailstock enables a CNC machine to precisely and safely process shafttype work pieces. The tailstock is typically used to support the components via the use of a live center. A live center is a cone shaped object with a Morse taper adapter that's inserted into the tailstock. The cone portion spins on an internal ballbearing mechanism.
