Pugmill Moisture


Pug is a product that is produced thru a pugmill (sometimes spelled as pug mill), a machine in which materials are simultaneously ground and mixed with a liquid. Industrial applications are found in bricks, pottery, cement and some parts of the concrete and asphalt mixing processes. In ceramics pug mills, or commonly known just as “pugs”, are not used to grind or mix, but rather they extrude clay bodies prior to shaping processes.

Having the correct pug moisture level has become a critical component during the production process. Being such a porous material, pug can easily become either too wet or dry wasting the manufacturer’s time and money.


By installing the MoistTech pug moisture sensor in the processing area, the user continuously monitors the manufacturing process with the ability to control the pug moisture content either manually or automatically.

The sensor should be installed over the conveyor transporting the pug, several inches above the belt, screw conveyor or any area where the material can be viewed. In the installations of spray or fluid bed dryer’s, optical windows or sampling systems can be provided.

Benefits of Pug Moisture Detection

  • Increased Equipment Life
  • Lower Energy Costs with Proper Dryer Control
  • Reduced Start-up Times
  • Less Waste & Downtime

Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.1% moisture and typical analog range is 0-10% moisture and up to as much as 40%, subject to application. The outputs can be adjusted to optimize PLC or recording requirements.
