design of a stirrer
(OP)
i would like to enquire how the design of a stirrer mechanism for powder material in a conical hopper can be done. is this the same theory you would find in fan design.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

I had a similar problem a number of years ago when involved in the design of a material feed system for a Rotational moulding machine. Whilst I didn't investigate stirrers available at the time, I did come up with a good solution. I piped compressed air into the hopper and pulsed it using a solenoid valve on the pipe. This worked very well for me as it agitated the material enough to prevent bridging. Hope it provides you with soome food for thought!

Also, sometimes it turns out to br more economical to resquirt and peletise your regrind, if you include effect of chip on stoppage and reject rates.
Remember when calculating cycle times and yeilds, to only include the mouldings you actualy get paid for.
