ACS Gypsum Wallboard Equipment

From pin mixer to wallboard, slurry shouldn’t come out too wet, or too dry.

Get the right mix with ACS Gypsum Wallboard Equipment to ensure that your wallboard is crystallizing at the right time, and in a way that will make a strong, lasting wallboard for any application.

Pin mixer

No lumps allowed

Lumps in your wallboard slurry can cause unwanted breaks in face paper and an unnecessary amount of downtime.

Our pin mixer components are machined top to bottom to ensure close internal tolerances. Mixtures won’t get stuck in your machinery, and your mixer will keep running efficiently to produce a well-mixed, lump-free slurry.

Get that chrome finish

Our mixers are measured pre and post chroming to ensure that your mixer has the right amount of chrome to prevent premature wear.

Measuring also helps the mixer internals maintain their tolerance.
