1. Mixing Volume ranges of common batch powder dry-mixers

Solids blenders can be ordered from manufacturers with quite a large range of sizes, from few liters to few or dozens of cubic meters. Solids blending is a volumetric process thus a volume should be specified when ordering a mixer, not a weight as the weight will vary with the bulk density of the solids. The table below shows the typical sizes of mixers that can be found on market.

Table 1 : Common solids mixers size range

Mixer Usual Sizes
Drum / Bin blenders
10 l in labs - 200 l industrial for drums
200 l - 2000 l for bins
Ribbon blenders 150 l - 5000 l
Bigger mixers are possible / special executions
Paddle mixers
100 l - 2000 l
Up to 5000 l for some manufacturers
Ploughshare type 100 l - 5000 l
Bigger mixers are possible / special executions

2. Minimum and Maximum mixing volume batch powder dry-mixers

The table below is presenting mixing time that can be expected from the most common types used in the industry. These are indicative values to have a rough idea when assessing a design or troubleshooting an existing system.

Table 2 : Typical Min and Max mixing volume

Mixer Min mixing volume Max mixing volume
Drum / Bin blenders
Diffusive mixers
- 50-60%
Ribbon blenders 30% 70-80%
Up to 90% may be possible
Paddle mixers 30-40% 70-80%
Ploughshare mixers
Shear mixers
30-40% 70-80%
