This is a new conveyor. We have been told the required delivery, (106 m^3/hr) the screw diameter (20" dia 3/4 pitch) and the length of 21 feet. We must make an assumption about the coefficient of friction but we have been told that the wet pulp has a density of 60lbs/ft^3. Operating time is 24 hr/day 350 days per year.
Get priceA higher filling rate corresponds to a higher efficiency of the screw conveyor. Therefore, when the friction coefficient between the particle and the screw blade is 0.2, the friction coefficient between the particle and the pipe wall is also 0.2 and the best filling rate of the TCP-SHV flow formed in the vertical screw conveyor is 70%.
