The shear force diagram crosses the base line at a distance x from the end of the beam, given by: Q x = 0 = V 0undefined - wx / 2 = 53undefined - undefinedx 2 / 2. and: x 2 = 106 x = 10.30 ft. Between x = 12 ft and x = 18 ft the load intensity is zero, and the shear force diagram is a horizontal line.
Cement Grinding Machine Selection: Vertical Roller Mill VS ...
The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers.

Shear stresses and material slip in high pressure roller mills
Fig. 2 shows typical curves of one experiment with quartz stressed with a specific milling force of 4.1 N/mm 2 at a roller speed of 1.0 m/s. The step-shaped form of the curves is due to the reading frequency of the transient recorder adjusted to 1 kHz. With this fraction, only about six particles contact the sensor surface of 20 mm 2, therefore, the curves scatter statistically.
