Jun 01, 2018 Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.

Use of ball mills to grind clinker and raw materials From the turn of the 20th century, rotary cement kilns gradually replaced the original vertical shaft kilns, used originally for making lime. Rotary kilns heat the clinker mainly by radiative heat transfer and this is more efficient at higher temperatures, enabling higher burning temperatures ...
To make white concrete powder, place 4 sand, 4 gravel and 1 white dye in the 3x3 crafting grid. When making white concrete powder, it is important that the sand, gravel and white dye are placed in the exact pattern as the image below.

A ball mill would do well for what you describe A rotating drum with the material and balls inside. Ball Mill example video 24 seconds As the drum turns, the balls rise along one side, then fall over, as a continuous wave. When the balls fall they smash the material. The longer the mill is run, the finer the product. Dry material works best.
Jan 24, 2019 Cement particles possess positive and negative charges when it ground into smaller particles. These charges make agglomeration of the cement particles and they become easier to adhere on the ball mill surface. Ethylene glycol EG absorbed on the cement particles and ball mill surface via the hydroxyl groups which neutralize this
May 22, 2019 The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body ball and the object to be polished material installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
18.104.22.168 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs nanosize using different sized balls.

Jan 22, 2020 Reduction of size The drying materials are then ground by using ball mills and tube mills to reduce the size of materials to find powder. Mixing in correct proportion The finely dried materials are mixed in exact proportions. The mixing may be done either mechanically or by pneumatic methodseg. pumped under pressure.
Dec 30, 2012 Posted December 29, 2012. I would suggest that you build a rod mill if you want to get the material down to a fine power, a ball mill usually is used to make bigger item smaller, e.g. big rocks down to little rocks, and then the material goes into a rod mills to take it down to a powder.
