Dec 31, 2017 It depends on your drive wheel size. On the grinders I make I use Leeson 3 phase 1800 rpm AC motors overclocked via the VFD to run at 2500 rpm. This drives a 6 drive wheel and give me plenty of torque at 20 rpm to full speed and runs any ceramic belt very well. With a DC motor like your using you should have near full torque at all rpms.

How to Size a Motor. by Kristin Lewotsky, Contributing Editor Motion Control Motor Association Posted 10312017 Proper sizing is a crucial aspect of motor selection. If a motor is undersized, it will not be able to control the load, leading to overshoot and ringing.
The problem with this approach is, while it works, it simply works too fast. Optimum roller speed for small homebrew mills is 150200 rpm. Drills and most AC motors run at 1,750 rpm U.S. 60 cycle AC. The answer is to use pulleys and belts or an expensive gear reduction motor to run your mill more slowly. Motors are ubiquitous.
Cons of using pulleys Getting the correct size vee belt can be difficult, A tension pulley or adjustment system may be needed in order to take up the slack as the belt expands due to wearusage. Belt slip can be a problem if there is a lot of resistance in the mechaninsm
Benefit of High Pressure Grinding Mill structure, so it has small footprint, strong system. with other mills, Raymond Mill has high passing rate 99. particle size80325mesh main drive device of Raymond mill adopts airtight gear box and belt pulley, the transmission is stable and the operation is reliable.
Using This Pulley and Belt Size Calculator. Enter the motor speed in RPMs. Enter the motor pulley size in inches. Enter the driven Pulley size in inches. Adjust the drive and driven pulley sizes, to achieve a certain RPM output. More than one stages of pulley speeds can be calculated in a compound drive system. The output of the first stage
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, pinion, gearbox, coupling, motor shaft and motor bearings By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

Aug 12, 2019 With a motor and VFD, the drive wheel can be mounted directly onto the motor shaft 24mm diameter on a 90frame motor. This saves the cost of the separate shaft, bearings, steppulleys and drive belt. It also allows the use of a face or flangemount motor, which can greatly simplify the design by eliminating many of the potential alignment issues.
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables the old fashion way.
