Mills Can Be Engineered to Meet Customer Process Requirements

Overview

Production Mills

(847) 548-0044

Standard Mills Include: Variable Speed Agitator, Product Feed Pump, Safety System & Electrical Panel

Production bead mills for wet milling, fine grinding and dispersing of liquid and paste type viscosities. Operation is on a continuous basis or by recirculation milling. Precise control of the mill agitator speed and pump flow rate assists in producing uniform products.  

Model Sizes
5, 10, 20, 40, 75, 100, 125 Liter Chambers  

The model number is the chamber void volume in liters. Minimum batch size is typically 4-6x the chamber volume. The correct mill size will process a complete batch with minimal losses and clean up required. If the mill is too small, the processing times will be longer. If the chamber is too large, the batch will finish in a shorter time but will require more clean up. Our team will assist with selection.

Operation

The EMI production mills will economically produce quality dispersions requiring fineness of particle. Products to be dispersed are premixed, and fed to the milling chamber with the included metering pump controlling process residence time. The water-cooled milling chamber is filled with small media and agitated by a centrally located series of disks creating intense shear and impact forces. Process quality is determined by product feed rate, agitator rotational speed, grinding media type, size and loading along with product formulation.

The new mills have increased cooling surface area for better temperature control. Standard mills include process monitoring meters and safety switches. Various materials of construction are available to meet the process requirements including polyurethane and ceramic.
