Gravimetric fillers: Improving high-speed package filling
Many dry bulk solids processors who use high-speed, continuous filling lines to package materials in pouches, small bags, and boxes are replacing volumetric fillers in their filling lines with gravimetric fillers. The need for long-term filling consistency, accountability, and lower material usage are just some of the factors driving this trend. After a brief look at high-speed filling lines and the differences between volumetric and gravimetric fillers, this article explains how gravimetric fillers can improve high-speed package-filling performance and how you can overcome obstacles to using the fillers in this application.
Volumetric filling equipment has long been the traditional choice for high-speed, continuous filling lines, primarily because of the equipment's low cost and simplicity. But gravimetric fillers can provide better long-term package-filling consistency, more accountability, and lower material usage in some of these applications. To determine whether a switch to gravimetric fillers makes sense for your high-speed filling line, you'll need to consider whether the fillers' advantages outweigh the equipment's higher cost and more complex operation and maintenance. First, let's examine some filling line and filler basics.
