FIELD: desintegrators and crushing devices.
SUBSTANCE: invention relates to devices for grinding materials, in particular to the lining of self-grinding mills, operating with the addition of balls in wet SAG grinding mode. Lining of drum mills of wet SAG grinding is made of composite of slabs with curved working surface. Surface is perpendicular to the flow of material flow, longitudinal grooves are provided for self-lining. Depressions are designed to freely accommodate balls and ore in them, which are fixed and unloaded when the mill drum is rotated. Section of the surface represents the cycloid curve of revolution with a height increasing against the direction of rotation of the mill.
EFFECT: lining is characterized by increased wear resistance.
