If van der Waals forced could bind silica to the spores in the mill those forces could also bind the silica to the spores after the milling process was completed It didnt happen It didnt happen On the other hand if there was not enough static charge on the spore to bind silica to the spore before it gets through the mesh filter there
The point where the mill becomes a centrifuge is called the critical speed Ball mills usually operate at 65 to 75 of the critical speed A ball mill is suitable for dry or wet milling of various material in cement fertilizer metallurgical industries and other industries Fig 23 is a ball mill
May 18 2012 A ball mill is a barrel usually made of a ceramic although for smallscale milling in the laboratory a small plastic bottle works well that rotates on its axis and is partially filled with a grinding medium called media in the form of spheres cylinders or rods Figure 201 shows a cross section of a ball mill The media is in such
