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

### Calculating HP for a cut Practical Machinist

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.

### Mill (grinding) Wikipedia

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

### Engine Horsepower Calculator Find Your HP

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

### Electric Motor Torque Calculation Formula & Torque

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

### Temperature Monitoring Is Key To Motor Reliability

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 Daycounter
