Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More

Critical speed and optimum speed ball mill binq mining jan 14 2013 how to optimise the speed of the ball millfaqs for instance a diameter ball mill has a critical speed of rpm you need now to determine the optimal speed which is about of the critical speed more detailedball mill is a type of grinder used to grind materials into extremely fine powder major parameters for ball milling
The critical speed of ball mill is given by where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm
In most cases the ideal mill speed will have the media tumbling from the top of the pile the shoulder to the bottom the toe with many impacts along the way the ideal mill speed is usually somewhere between 55 to 75 of critical speed
Jun 26 2017 ball nose milling without a tilt angle ball nose end mills are ideal for machining 3dimensional contour shapes typically found in the mold and die industry the manufacturing of turbine blades and fulfilling general part radius requirementsto properly employ a ball nose end mill with no tilt angle and gain the optimal tool life and part finish follow the 2step process below see figure 1

Dec 01 2013 the ball diameter of 5 mm is optimal at 50 rpm of rotation speed the resultant average particle size of the milled powder is 23 m ball diameter of 3 mm is optimal at 100 rpm 14 m and 2 mm is optimal at 153 rpm 084 m from this result it can be said that the optimal ball size for efficient milling decreases with the rotation
Passfire has some great articles on the construction of ball mills including interactive calculators for the optimal speed vrs jar diameter of course lloyds work is also available and highly recommended by all but getting a passfire membership gives you so much more than just ball mill plans

Aug 11 2007 this additional reduction of 135075 or 1467 means that the container should theoretically rotate at 400467 rpm or about 85 rpm i measured a speed of 80 rpm the slightly lower speed due to frictional losses so basically your final speed will depend on 1 motor speed 2 your axle and pulley diameters and 3 your container diameter
