C-control

DISPERMAT® - control with extensive process control, data interface and integrated data base

The C-technology enables an excellent process control as all measurable values as well as the current height of the dispersion tool are indicated on the display.

Indications in the display

• Speed of the dissolver shaft, timer, torque, product temperature and power input
• Peripheral speed of the dispersion tool
• Current height of the dispersion tool (only with dissolvers)

We would like to introduce the latest process technology for the control and data collection with the DISPERMAT® dispersion systems.With this the experiences of our customers as well as our own ideas have been realised. The new C-technology represent the essential innovation for the handling, safety engineering, process control and documentation for dispersion and fine milling.

• Data base of the C-technology
• Dispersion and fine milling systems with C-control

1. Power compensation with the C-technology

Relationship between power input and dispersion result:
The mechanical power that is transferred into the millbase is closely related to the dispersion result. The mechanical power determines the energy that is transmitted by the dispersion tool or the milling rotor via the grinding beads to the product. The power P is calculated from the speed n of the dispersing tool and the torque M generated on the dispersing tool according to the following equation:

The higher the energy density, the greater the probability that more agglomerates are also dispersed.


For the exact definition of the power that is transferred into the millbase it is absolutely necessary that all frictional losses which are not generated by the stirring and dispersion process are eliminated and that the calculation is only made with the real net power value.

With the new C-technology the power under no load which includes all frictional losses such as ball bearing friction, motor ventilation, mechanical seals etc. as well as the net power (without frictional losses) can be measured. The power compensation is made as follows: The motor is ramped up automatically in steps from 0 up to the max. speed. On each speed step it dwells for a moment, measures the power under load and restores the measured value back to 0. The power curve is represented and stored graphically step by step. In the following dispersion process the measured power value is reduced automatically by the stored power under load.


As a result of a single power compensation over the complete speed range, operation with the net power is possible. With the C-technology dispersion with a constant power input is also possible. For this the speed is adjusted during the dispersion in such a way that the product of n and M results exactly in the preset mechanical power transferred into the millbase.

With the new C-technology the no-load output containing all friction losses such as ball bearing friction, motor ventilation, mechanical seal etc. can be measured as well as the net output (without friction losses).

2. Cut out values with the C-technology

In order to protect from undesirable process variations, up to three cut out values can be defined. The following cut out values are available: product temperature, power input or speed and torque. When reaching a cut out value the instrument can either stop or continue to operate further at a pre adjusted constant speed.

3. Data recording with the C-technology

The measured values can be recorded as well as presented graphically. The data can also be stored for a later evaluation. Due to the free scaling of the graphics striking results can be presented. The cursor function allows the indication of the numerical values at any point on the graph. In addition simultaneous data transfer to the recording software WIN-DISP is possible.

4.Data base of the C-technology

The data base can store up to 100 dispersion parameters sets including the cut out values with a name edit function. Furthermore the used container or milling bead volume can be memorized. The stored dispersion parameter sets can be easily loaded by the operator to ensure a standard treatment of his products.
