The type of diaphragm that suits a defined application can be found based on the following criteria: Mill type: cement mill, dry process raw mill, wet process raw mill. Diaphragm location: Raw mill: transfer diaphragm at the drying chamber outlet, intermediate, peripheral discharge for a double rotator mill and outlet diaphragm.
Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits. According to the need ball mill can be either for wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.
During treating oily sludge of tank bottom by water-based extraction, two key problems, such as difficult separation of oil and solid phases and high water and solid contents of the recovered oil, need to be solved. A combined process based on the core technology of "ball mill + flotation" was used to study its treating effect for this oily sludge.
