Wet grinding. The dry ground mica powder with an average D 50 of 5. 8 μ m was further milled in ethanol using 500 μ m balls in order to reach a D 50 of less than 1 μ m. To provide more friction surface as indicated in the recommended rules, a 60-30-10 filling was first tested.

One is using water, known as Wet Grinding and the other is Dry Grinding, without water. Wet grinding creates more smooth mica powder compared to the dry grinding process. Let us see both the process and what sieving and filtering equipment are preferable for it.

53100 Mica, fine, wet grinding. Mica are potassium-aluminium silicates. Wet ground mica are a mixture of 36 % aluminium oxide (alumina) and 47 % potassium oxide (silicid acid). The remaining 17 % are 10 % potash and small amounts of iron oxide, fluorine, magnesium oxide, water and sodium carbonate. Appearance: .
