Laboratory Research & Small Batch Production
​

Pilot Mills are used for wet milling, fine grinding and dispersing of fluid or paste type viscosities and recommended for product research, development and small batch production. Information developed on the Pilot Mill will help predict production expectations.

Mills operate on a continuous basis or by recirculation milling. Precise control of mill variables including product flow and agitator speed allow the user to mimic production equipment.

Also available is a combination Mini/Pilot Mill. High flow recirculation of a small volume by using a feed funnel located directly over the back chamber reduces the volume required for milling. The Mini/Pilot mill can be converted to the external feed pump for processing larger volumes or higher viscosity dispersions.

General Operation


  • Dispersions to be processed are metered through the milling chamber and agitated bed of grinding beads using the provided variable rate feed pump. 
  • Agitator rotational speed is variable allowing complete control of the shear and impact forces required for efficient dispersion
  • Product quality is controlled by mill residence time, bead loading and agitator tip speed as well as product formulation.  
  • Single pass processing or recirculation milling can be used to process dispersions.
  • Various grinding media's can be used including glass, ceramics and steel. 
  • Capable of producing sub-micron particles 
  • Information obtained from milling on the Pilot Mill will help to predict production expectations
  • Monitoring of process functions provide data for batch to batch reproducibility. 


Mill Selection 


Different mill sizes available to meet the batch size range required. The model number indicates the chamber void volume in liters and two to four times the chamber volume is a typical minimum batch volume. Larger volumes can be processed on any model with processing time dependent on the required results. Once the batch is completed a suitable solvent can be used to purge and clean the equipment. Quick release chamber closures are used to make the equipment easy to maintain.
