How much, and what, do you want to mill ?

You will be sucking into a mill and that would reduce/eliminate fugitive material.

The sucker would have to stop to let the material get into full contact with the hammer whirly around bits. Otherwise you will suck most of the feed straight through.

Tell me there is a strainer device on the mill outlet and I'll tell you it will clog.

Tell me it self cleans and I'll ask "Where to?"

Once you have solid moving in an airstream it must be moving fast enough to carry the max lump size you will try to crush....straight through the gadget

Your question relates to the mill feeder. Existing purpose made feeders providing batch feed are your available choice options. ■

I know a suction hammermill can, but what about conventional hammermill?

Has anyone done it before.

As my friend Louis has so well explained it will

not work with your desired expectations

due to the issues he has described.

You need both elevation and gravity to be your friends

when it comes to conventional hammer mills.

As far as fugitive dust is concerned the issue is control and

unless you have suction hoods over the discharge point that are

timer controlled to stop after x minutes of hammer mill shut down

all is discussion moot.

The other issue is dust control as the fine dust has to be contained if you are

in a country with environmental fugitive dust regulations and this entaikls the

use of bag houses or a flue scrubber of some type whether water based or electrostatic

if and only if it is possible to use a SCRUBBER WITH AN ELECTROSTATIC CHARGE SYSTEM. ■
