What are the Differences Between Dry and Wet Type Ball Mill

What Are The Differences Between Dry And Wet Type Ball Mill

Jun 29, 2021 3 Wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5-10 lower than that of dry ball mill. 4 The grinding particle size is fine and uniform, and the wet ball milling can not only grind agglomerate into fine particles, but also mix the lean material and the plastic material well.

Feb 20, 2017 This should be compared with 40-45 in wet grinding. The expression used for this phenomenon is that the charge in a dry grinding mill is swollen. Big dry grinding ball mills are often two-compartment mills, with big balls in the first compartment and small balls or cylpebs in the second one. An extra grate wall is used to separate the two charges.
