• An Analysis on the Development of Ball Mill

    If we simplify ball mill as a beam and calculate the strength according to the plane bending, torsion and deformation, the result can be too rough. The reasons are as follows: 1 There isn''t much difference between the diameter and barrel length, so it doesn''t accord with the assumption of simplified supporting beam ( the beam length can be over

  • What is a Shear Force?

    For example, a force of 10 newtons (N) is exerted at the edge of a beam. This is an external force. Since the beam is a rigid structure, the force is internally transferred all along the beam. This internal force is known as shear force. The shear force between one end and the other is usually plotted on a shear force diagram.
