THE MECHANICS OF TENSION CONTROL

Remember the equation of torque = tension x radius is linear so torque must be decreased (for unwinds) and increased (for rewinds) at a linear rate relative to roll radius For example if you start with a 17 5 inch roll radius (35 inch diameter) and unwind down to a 1 75 inch core radius (3 5 inch diameter) 17 5 divided by 1 75 is 10 1 ratio

How it Works Crushers Grinding Mills and Pulverizers

Buhrstone mills are one of the oldest types of mills used for grinding grains and hard materials Disk attrition mills are modern versions of the ancient Buhrstone mill Vertical shaft mills work on the same principal as VSI crusher with a rotor on a vertically mounted shaft using centrifugal force to throw the media against a wear plate

Analysis of Flow Field in Vertical Roller Mill Chamber

According to the two-phase turbulent coupling characteristic of powder hot-air flow field and the operation data of the vertical roller mill chamber it analyzed three-dimensional flow of the chamber using standard turbulent model RNG turbulent model and Reynolds stress equation model (RSM) The results show that high pressure flow region enhancing separation efficiency is formed between the
