The Caleva Mini-Mixer:
Operating mechanism

The unique two blade, contra rotating, dual speed, high shear, mixing and blending system ensures efficient mixing without applying unnecessary work to the system.

The two specially designed mixing blades rotate in opposite directions with the secondary shaft rotating at twice the speed of the primary shaft. The secondary shaft with the split blade wipes the material from the slower rotating primary shaft at each turn. This action ensures a complete and thorough mixing of the material in the mixing bowl within a few minutes.

Mixing time and speed can be programmed and standardized. If sample sized are maintained then mixing equivalence can be maintained over several batches.

For smaller sample sizes a “half bowl” unit can be used. This can be added to the system at the time of the current purchase or later.

Terminology:

Spheronisation™*, Pelletisation and Marumerisation all mean the same thing. The manufacture of small round pellets with a limited size spread within a batch. Pellet sizes (sometimes called micropellets or spheroids) can be normally be made within tight size ranges between about 0.5mm and 2.0mm in diameter.

* = Sometimes called: Spheronization or spheroidization.

Trade Marks:
Spheronization™ was a term originally coined by Caleva Process Solutions and used by Caleva as a Registered Trade Mark. It is still used as a trade mark of Caleva Process Solutions and other uses are prohibited.

The mixer granulator can be used with or without the supplied insert optionally to further reduce mixing batch sizes for some products. Suitability depends on the characteristics of the products being mixed.

Two different mixing bowl sizes are available depending on your requirement.

Both units use the same bowl and unique Caleva design twin blade, contra-rotating, dual speed, mixing action.

The Caleva Mini Mixer/Granulator:

Primary "split" blade mixing speed control by operator between 25 and 150 rpm
Primary "split" blade mixing speed digital display
Secondary mixing blade at 2x the speed of the primary blade
Powerful 300 kw motor
Feeder inlet for addition of material to the mix
On/Off switch
Operator controlled automatic run timer
Safety interlocks
E-Stop

The "Datastor" Caleva Mini Mixer/Granulator

As above but with the additional option to plug in your computer and record and show in real time:-
- Product temperature in the mixing bowl (infra-red remote sensor)
- Primary blade rpm and total revolutions
- Power usage (current and total power used are recorded)
Data can be stored and printed as a one page summary for permanent hard copy record keeping. Data is also stored electronically in the attached computer.

Small design to easily fit on the bench top.
