STEPPING FORWARD USING VARIABLE SPEED DRIVES FOR OPTIMIZING THE GRINDING PROCESS IN SAG AND BALL MILLS I Atutxa and I Legarra Ingeteam Power Technology Parque Tecnológico de Bizkaia Edificio 110 Zamudio Vizcaya Spain GRINDING PROCESS IN SAG AND BALL MILLS ABSTRACT
filling in a laboratory ball mill would imply the maximum agitator shaft speed and 30min milling time Keywords fat filling ball mill milling variables physical properties sensory characteristics optimization Fat fillings contain high amount of fat 30–40 which presents a continuous phase and determines the consistency of the filling
Ball Mill EnergySaving Principle Usually ball mill operates at fixed running speed and the cylinder speed is determined by belt pulley and gear reduction mechanism or hydraulic coupling The rotating speed of ball mill directly affects the movement of steel balls and the grinding process of material
The ball mill is a key piece of equipment for grinding crushed materials and it is widely used in production lines for powders such as cement silicates refractory material fertilizer glass ceramics etc as well as for ore dressing of both ferrous and nonferrous metals The ball mill can grind various ores and other materials either wet
The influence of both formulation and processing variables on the physical characteristics of milk chocolate has been studied during milling with a pilot ball mill Nine experimental millings were carried out varying the type of dried milk used
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill
