Ball mill introduction. Structurally, each ball mill consists of a horizontal cylindrical shell, provided with renewable wearing liners and a charge of grinding medium. The drum is supported so as to rotate on its axis on hollow trunnions attached to the end walls (attached figure 1 ball mill). The diameter of the mill determines the pressure ...
The maximum stress values were registered in the region where the failure occurred, near throughholes used to bolt the ball mill's cladding plates. The ball mill was redesigned to ensure high endurance for the equipment. Therefore, internal and/or external reinforcement rings were inserted in the structure, and the maximum stresses calculated ...
The work herein presented analyses an existing failure in a ball mill of a cement production line. • The failure is recurrent and responsible for reducing the period between overhauls. • The ball mill was redesigned to ensure high endurance for the equipment. • The maximum stresses in the redesigned structure were reduced by 32%. •

Ball Mills. Although ball mills were first introduced in the 1860's, the main progress was made during the 1870's to 1900's in Germany, where its growing cement and chemical industries ...
The cement ball mill is a kind of cement grinding is mainly used for grinding the clinker and raw materials of the cement plant, and also for grinding various ores in metallurgical, chemical, and electric power has the characteristics of strong adaptability to materials, continuous production, a large crushing ratio, and easy to adjust the fineness of grinding products.
A material mixture is kept in a bin with a capacity of 70 t that is supplied by a cement ball mill. Dust and fly ash are supplemented after the ball mill depending on the required kind of cement. The cement is then transferred through a bucket elevator to the next separator. Particles comprise the final product that is supplied to the cement silo.
