Abstract
La plaque de blindage (1) a deux faces supérieures (4,5) inclinées formant un profil en redan, apte au relevage des boulets. De préférence l'angle d'inclinaison (α) de la grande face amont (4) est compris entre 13 et 17°, et l'angle d'inclinaison de la petite face aval par rapport à la grande face amont (4) est compris entre 50 et 60°. The armor plate (1) has two inclined upper faces (4,5) forming a step profile, suitable for lifting balls. Of preferably the angle of inclination (α) of the large upstream face (4) is between 13 and 17 °, and the angle of inclination of the small downstream face relative to the large upstream face (4) is included between 50 and 60 °.
La plaque (1) a une face avant (9) et une face arrière (11) inclinées du même angle (β) . Deux plaques contiguës (1,1′) délimitent une cavité (12) dont lesdites faces avant (9) et arrière (11) constituent les parois d'écoulement de la matière. L'angle d'inclinaison (β) est compris entre 25° et 40°. The plate (1) has a front face (9) and a rear face (11) inclined by the same angle (β). Two adjoining plates (1.1 ′) delimit a cavity (12) whose said front faces (9) and rear (11) constitute the material flow walls. The angle of inclination (β) is between 25 ° and 40 °.
La matière pelletée dans la cavité (12) se déverse dans la zone de retombée des boulets (3) lors de la rotation du broyeur. Figure 2. The material shoveled into the cavity (12) pours into the ball drop zone (3) during rotation of the mill. Figure 2.
