The horizontal design makes it easy to operate and maintain, and it is suitable for both wet and dry grinding. 2. Vertical Ball Mill. A vertical ball mill is a type of ball mill where the barrel is vertical instead of horizontal. It is designed for fine grinding of materials, and it is usually used in laboratory or smallscale production.

Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...

the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application. The critical speed of a ball mill is calculated as divided by the square root of the radius in feet. The rotational speed is defined as a percentage of the critical speed. Smaller diameter mills

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

And the motor realizes the operation of the ball mill through reducer. During the operation,the hollow shaft in the center of the ball mill drives the mill body to rotate under the driving of the power system. • Edge driving ball mill: the motor drives the gear on the edge of the cylinder through the reducer to drive the cylinder movement. 6.

how to choose motor for ball mill The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a finetoothed belt on it. It was left in place and it seems to . If choosing with optional vacuum jar, it can grind samples under the vacuum condition or filled with inert gas. ...

Step 3: Motor Curves. A motor's speed, current draw, power, and efficiency are often plotted against the output torque to make their values easier to visualize. The equations for these curves are all derived from the four specifications discussed above using equations 1 through 4 of the previous few pages.

versa. The ball screw drive consists of a ball screw and a ball nut with recirculating ball bearings. The connection between the screw and the nut is made by ball bearings that roll in the matching forms in the screw and ball nut. The forces transmitted are distributed over a large number of ball bearings, giving a comparatively low relative load

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

I have an issue to select a proper motor. I see some challenges here : 1The jar will contain metal balls which will be a heavy load to rotate. (I think 1/3 HP at least would be needed) 2The jar rotation should be constant (80 RPM). 3It will run for long time < at least for 11 continuous days.

The power supply needs to be able to deliver the voltage and current for your chosen motors and controller. Going bigger on the current won't hurt but the voltage needs to match the controller's voltage. So for my old cutter, I used 4 x 57BYGH56401A NEMA 23 rated at amps and the controller needs 2 amps.
