Sawdust Blower system3/14
Hello All, I purchased a sawdust collection system from an old furniture factory. It is a 12 inch collection, Blower fan is 24 inch blade, with a 15 hp 3ph motor. I just built a sawmill shop and planer building 32 x 50 to saw plane and assemble products.
1st I need assembly information to set up this sawdust system to blow into a box trailer.
2nd is I don't think I need a 15 hp 3ph motor as my system is much smaller than the mill this equipment came from and would like to know how to determine what size motor I can run this fan. I have a 5 hp 1ph 220 compressor motor and may want to use that. I may be limited to available power as I am in a very rural situation.
3rd I have not found information on running such a system and would like to have web links that could assist me in achieving the knowledge to understand this equipment.
4th it will collect sawdust from a CKM m-419 4 sided planer, Timber Harvester bandsaw mill and various other wood working machines.
Any help, advice and information links would be very appreciated.
Im no fan dynamics guy but I cant personally fathom how a fan that was equipped by the manufacturer with a 15HP motor is going to move barely anything with a 5HP single phase compressor motor.
I dont think your going to find anything on the web that you havent already found in a google search.
You would likely need to contact a company who sells and designs transfer fans and blowers and hope they are willing to give you some free advice.
Blowing chips into a trailer isnt really a major affair. Blower, suction side piped to tool, outlet side poked through the side of the trailer, push the button.
The issue will be when your four sided swamps the 5HP motor on your fan and the whole thing goes kaflooey. Im honestly not sure a 5HP single phase fan would cover a really large single sided planer that was able to hog off a lot of material.
Xj, Please see attached. These are CFM values at specified velocities. If the 4 sided planer has 6" diam hood outlets, they will require 880 CFM each at a velocity of 4,500 FPM (coarse particles, heavy loads). A CFM requirement of 3,520 after resistance of piping etc, may require a 15 HP dust collection blower itself. Also, as far as transfer fan, I would follow Mark's suggestion. Curt
