To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x m = 1 Nm. Typically, a safety factor is used so that the ...

Ball Mill Model The main structure of the ball mill is composed of three parts, namely the feed inlet, the cylinder part (work bin), and the discharge port. Figure 2(a) shows the structural model of a ball mill. In the mill cylinder part, there are lifters for turning over the particles. The quartz sand particles enter the cylinder through a

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
