Description This worksheet calculates the maximum axial load that a section of drillpipe can be subjected to when setting the slips to avoid crushing by the hoop stress imposed by the slips. It assumes that the drillpipe, slips and bowl are in good condition and that the slips are set with slow movement down (ie no shock loading). User input 5

Adjustment of discharge grain size: wedge or gasket adjustment device is installed between two roller wheels, and adjustment bolt is installed at the top of wedge device.
· Construction Working Process: It contains two pairs of rolls, and the rolls in each pair rotate toward each other. The rolls are corrugated, and one roll of each pair turns faster than the other one. This results in a shearing action instead of the direct pressure that is brought about in the ordinary crushing rolls.
· The load of crushing from feed roller is acting at an angle of 550 from left side=275 ton=2750 KN The vertical component of load= KN The horizontal component of load= KN (right) The weight of top roller is 32 ton which is acting downwards. The total vertical load acting on the roller = 6645KN
