1 Introduction
1.1 Destination
This BEVS2501/1 laboratory mixer has been designed for blending multi –component
formulations. It is really helpful device for dispersing small to medium size quantities of varying
viscosities.
The built in frequencer allows to regulate the RPM of working shaft. The RPM is indicated on
touch screen panel.
There is many impeller configuration available as requirement, and also provide customized
versions upon request.
The necessary for dispersion is optimal circumference velocity. When we use the mixer disc of
different diameter, then circumference velocities may be calculate by the following formula:
υ = (3,14 · d · n) : 60 [m/s]
where:
d = disc diameter [m]
n = RPM of the shaft [RPM]

(cooling or heating water) –when necessary.
3 Working
Before start make sure that:
---The dispersion disc is lowered in working vessel –if not then you can not start the engine (safety
