Questions we are asked most

How long should a powder blending cycle take?

Most industrial ribbon and plough blending cycles land between 5 and 15 minutes. The correct figure depends on the material, the fill level and the impeller design, not on the machine alone. A cycle run much longer than that usually indicates the fill level is too high or the material is not matching the mixer type. The mixing time guide covers this in detail.

What fill level should a mixer run at?

Between 55 and 70 percent of working volume is the usual range, because powders need room to circulate and two or three times the batch mass in movement. Running a mixer nearly full gives poor uniformity and much higher motor load, while running it very low wastes installed capacity and can leave material static on the wall.

How do I know whether my problem is mixing or conveying?

Sample the material at three points: straight out of the mixer, after conveying, and from the finished pack. If the mixer output is uniform but the pack is not, the fault is in conveying, vibration during transfer or the packing step — not in the mixer. This test resolves the question quickly and saves specifying the wrong equipment.
