Several energy efficient options for cement grinding are available today such as vertical roller mills roller presses (typically in combination with a ball mill) and clinker pre grinders with ball mills Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation
There is a specific operating speed for most efficient grinding At a certain point controlled by the Mill speed the load nearest the wall of the cylinder breaks free and it is so quickly followed by other sections in the top curves as to form a cascading sliding stream containing several layers of balls separated by material of varying thickness
Energy Efficient Ball Mill The energy efficient ball mill is an efficient tool for grinding many materials into fine powder 2 The energy efficient ball mill is widely used in powder making production line including cement silicate new type building material refractory material fertilizer ore dressing of ferrous metal and non ferrous metal glass ceramics etc it can grind various ores
As grinding equipments ball mills and rod mills are both high efficiency grinding equipments Their common points are 1 They have the same function they are all used to grind materials so that the materials can reach the state of powder 2 The shape of ball mills and rod mills are similar they are all horizontal and rotatable cylinder 3
To achieve a reasonable efficiency with ball grinding mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced Various classifiers such as screens spiral classifiers cyclones and air classifiers are used for classifying the discharge from ball mills
From the above is then evident that for efficient fine and very fine grinding of solids either very high compressive forces of a particle bed or intense stirring with small grinding media must be used The German development of high pressure roller mills is an example of the first principle while mechanically stirred ball mills will be of the
