Pugmills

Here are some main pugmill features that can help you in your decision making.

Stainless Steel vs Aluminum:
Stainless steel is better long term, best for everyday porcelain users
Aluminum is good for stoneware users

Twin Auger vs Single Auger:
Twin augers increase wedging capability when pugging leather hard clay with softer clay (churning the clay together)
Twin augers pull the clay through the chamber, alleviating the need to push the handle down to move clay through the hopper and into the barrel
Single augers are meant to push clay through the barrel

De-airing vs Non De-airing:
De-airing pugmills have a vacuum unit attached therefore removing 100% of the air in the clay
Non de-airing pugmills can remove either some or most of the air in clay, depending on the size of the barrel versus the size of the nozzle where the extrusion occurs

Pugmill vs Pugmill/Mixer:
Pugmills are for reclaiming clay when the clay is at a specific consistency
Pugmill/mixers can mix wet, dry, and leather hard clay to reclaim clay into new clay
