Under ideal working conditions, Raymond Mill consumes less energy than other ordinary grinding mills. For example, the MTM Mediumspeed Grinding Mill only consumes /h when yielding a ton of materials and /h when feeding a ton of materials. Its electricity consumption is lower than that of ball mill at the same level by over 60%.
