Batch measurement.


Dissatisfaction with current routines for estimation estimation

In mathematics, use of a function or formula to derive a solution or make a prediction. Unlike approximation, it has precise connotations. In statistics, for example, it connotes the careful selection and testing of a function called an estimator.
 of mixed compound properties is said to be the subject of many articles, discussions and projects. The estimated properties of compound measured in existing test devices by taking a small sample from the total batch do not reflect with required confidence the real characteristics of the total batch, nor necessary parameters which can define further processability of the compound, according to according to

These tests, as a rule, do not allow for defining the impact of a particular technological stage in the development of the compound properties indices. For example, in the two-stage mixing process, tests are usually performed during the second stage (final batch stage). So the impact of the most important of the compound properties, masterbatch stage, is nearly completely hidden. The impact of batch-off mills/extruder on the compound properties can make things even more complicated.

The company's technique presents an alternative way of estimating compound properties. It is based on the assumption that the torque/power of mixing devices such as mixers, mill and extruders, together with other available online parameters like temperature, ram position and pressure in their dynamic evaluation can provide a clear picture of the compound quality parameters, such as dispersion dispersion, in chemistry

, distribution and viscosity. This estimation is done for the batch in total, and not just for a small piece of it, in real time, which allows the possibility to check the quality offline and control the process online, which in turn provides the possibility to achieve maximum batch-to-batch uniformity and requested compound properties.

This approach can be applied to the mixer mixer, either of two electronic devices in which two or more signals are combined. In the type of mixer used in radio receivers, radar receivers, and similar systems, a signal is translated upward or downward in frequency. , mills and extruder, and is embraced in a complete system which can optimize optimize - optimisation  the mixing process of a particular device with the aim of maximum efficiency optimization optimization

 of the total mixing process.

Process indices estimated by the company's control system can characterize the mixed compound properties more precisely than traditional methods for factory mixing. These values can indicate processability for steps such as calendering calendering, a finishing process by which paper, plastics, rubber, or textiles are pressed into sheets and smoothed, glazed, polished, or given a moiré or embossed surface. , extrusion and molding.
