For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultrafine powders, are normally attained by several stages using diverse crushing and grinding machines.
The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material glass, zircon oxide, steel) and the product to be dispersed.
