Step 1: HP = X B X C X L HOW TO SELECT A MINE HOIST.
The ball mill, driven by a 1.5 hp motor, operated at a fixed speed of 53.8 rpm. This speed was 78.5 percent of the critical speed. The normal operating ball load was set at 230 pounds, and was comprised of 2.5, 2 .

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Unit power (hp/in³/min) = Spindle horsepower (hp) Spindle horsepower (hp) ÷ Machine efficiency (%) / 100 / 100 = Motor horsepower (hp) Spindle horsepower (hp) × 63,030 × 63,030 ÷ Spindle speed (RPM) = Spindle torque (in∙lb)
drawing less than 1 hp (.75 kW), to 16-18 feet diameter, drawing 2100-3900 hp (1550-2900 kW). Feed size is usually ½ inch or less; product size ranges from 500µ to below 5µ. Ball mills work well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills
21.03.2009· Now the Haas Mini-mill can come with a 7.5 HP motor. But it has 33ft lb of torque at 1,200 RPM. I don't know if the Mini-mill motor is the same or equivalent to the VF-0 motor. If they ARE similar that 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases.
To calculate the KICK's and Rittinger's coefficients following formulas can be used = Ball mill A typical type of (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their
How To Calculate Your Horsepower. Horsepower is a way to measure the power output of an engine or motor. There are different formulas to figure out the amount of horsepower your engine is making. For this calculator, you have the option to use the Elapsed Time Method, the Trap Speed Method, or the RPM & Torque Method. Of course, the best method to figure out how much power your vehicle is
AC 1 HP single-phase AC motor has an input voltage of 230V, the input current of 3.8 Amps and working at 2500 rpm, 0.8 pf, 100% load. Calculate the torque of the motor. Apply our formula 1, T (N.m) = 230 x 3.8 x 0.8 x 100% / (2 x 3.14 x 2500 / 60) = 2.66 N.m. The torque produced by the motor is 2.66 Nm. Hence 1 HP motor can produce 2.66 N.m
In the most common speed ratings, the NEMA designation of medium motors includes ratings of 1/2–500 hp for 2- and 4-pole machines, and up to 350 hp for 6-pole machines. Temperature rise limits for large motors—i.e., those above medium motor ratings—differ based on the service factor (SF). Table 2 lists the temperature rise for motors with a 1.0 SF; Table 3 applies to motors with 1.15 SF
Lead Screw Torque and Force Calculator. When designing machinery that uses lead screws, it's a common task to try and figure out the size of motor needed to drive a given force with a lead screw. This calculator will calculate torque given the lead screw parameters and the required force. There are two torques the torque to raise the load and the torque to lower the load. Once the torque is
Only SINAMICS PERFECT HARMONY variable frequency drives (VFDs) were able to meet the three critical criteria for the mine’s ball mill applications: sufficient starting torque, clean operation over a wide range of speeds, and improved uptime and availability. Together, the drives’ variable speed capability and Advanced Cell Bypass technology allowed the mine to maximize throughput while
