立即联系/Live ChatIn Grinding selecting calculate the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize “just in case” Well this safety factor can cost you much in recovery and/or mill liner wear and tearThis specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample Specific heat is just the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K Read on to learn how to apply the heat capacity formula correctly to obtain a valid result
立即联系/Live ChatDec 15 32 I m just wondering what everybody prefers to use when 3D milling with ball mills My dealer tells me that old school people use step over by distance while new school programmers use the scallop height Well I guess I m old school I ve always used step over by distance I m finishing a race track shape with a 1/8 ballDec 10 32 This is often messed up when people are doing air conditioning calculations RE How much heat comes from an electric motor All the input to the motor is finally converted into heatif the driven equipment is doing the work within the room for eg a grinding wheel all the energy is converted into heat with in the roomIf the driven
