FAQ: Feeding & Blending

How to get better blending?

1.  Blend it up close 

2.  Say no to static 

3.  Pay attention to receivers 

4.  Thwart those bridges

5.  Learn to deal with regrind

Compounding feeders that don’t feed accurately typically produce off-spec finished products and require extended periods of downtime to recalibrate or fix, resulting in decreased production rates and lost profits. In all industries, the improvement in accuracy performance by even 0.025% of ingredient feeding can result in significant overall profits.

Proper installation, ideal weighing configurations, and appropriate choice of weighing controls can result in the avoidance of a variety of future feeder problems. For a complex feeder system—such as multiple loss-in-weight (LIW) feeders feeding powder and pellets into mixers or extruders—external influences such as vibration, platform stability, and upstream/downstream equipment connections can all affect a feeder’s performance. Informed knowledge of the significance of these influences is key to optimizing its performance. 

How to optimize feeding technology?

It is expected that feeder controls can easily connect to industrial networks and key process data, which has become a critical criterion in evaluating not only feeder performance but also real-time indication of the complete process.
