FIELD: mechanical engineering; cleaning of bead mills.
SUBSTANCE: invention relates to servicing of equipment for production of coloring induline-black composition, particularly, to casual preventive cleaning of bead mill. According to proposed method, after discharging black coloring composition from mill, tribochemical interaction of aluminum oxide or hydroxide with carboxylic acids used in production of coloring composition C10-C20 is done. Process is carried out without oil component and tribochemical catalyst for 40-90 min, using as solvent any component of black coloring composition or their mix in any ratio. Degree of cleaning of bead mill from remnants of black dyeing composition is 91-95%.
EFFECT: making mill good for repair or other chemical process.
