milling them in a miniature ball-mill. Non-lipid contaminants were removed using the method of Folch et al. (1957) with two washes in HCl : saturated aqueous NaCl (1:1, v/v), and the third wash with distilled water. A blank was used in which the whole process of extraction and washing was performed in the absence of tissue.
Ball mill is a piece of important grinding equipment, which is widely used in mineral processing, building materials, and the chemical industry. It can be used for dry or wet grinding of various ores and grindable materials. However, the noise generated by ball mills in the production process is extremely loud and can easily damage the health of workers who …
