Power calculation for Ribbon blender for dry cement mixing?

Click For Summary

Discussion Overview

The discussion revolves around calculating the power required for a ribbon blender used for mixing dry cement. Participants explore the parameters involved in the power calculation, including the dimensions of the mixer and the density of the material being mixed.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant provides specific parameters for the mixer: density of 1600 kg/m3, diameter of 1m, length of 2m, and a mixing quantity of about 2 tons.
  • Another participant suggests looking up typical motor power used for similar mixers, indicating that visual references from Google Images might be helpful.
  • A later reply questions how power calculations differ between liquid and dry mixing, specifically mentioning the role of viscosity in liquid mixing.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specific power requirements for the ribbon blender, and there are multiple viewpoints regarding the approach to calculating power for dry mixing versus liquid mixing.

Contextual Notes

The discussion lacks detailed assumptions regarding the mixing process and does not clarify the mathematical steps necessary for calculating the power required for the blender.

Welcome to the PF.

What motor power is typically used for such mixers? If you use Google Images to find similar size mixers, you should be able to see what size motors they are using... :smile:
