  • the grain size distribution of the material to be ground is an important quality feature. In particular, it can influence the yield of the further components connected downstream of the mill system, such as, for example, the flotation.
  • the aim is to achieve the highest possible throughput with high product quality and with low energy consumption and material requirements, ie costs.
  • the present invention thus relates in a preferred application to rolling systems, product processing systems and grinding systems containing rollers or roller pairing, as well as corresponding methods for the optimized operation of such grinding and rolling systems or product processing systems.

  • Milling especially grain milling
  • the influence of the various factors that determine the dynamics of a process is usually well known and in which the relevant processes can therefore be easily parameterized using appropriate equations and formulas or the equipment and devices involved simply activated and regulated accordingly
  • the number of relevant factors that influence the grinding quality and, at the same time, the yield of the processed end product is extremely high in milling. It is therefore often necessary for a miller, as a human expert, to manually adjust and set the entire grinding or milling system after analyzing the starting / raw material based on his intuition and know-how in order to obtain the best possible results in the sense of the expected Quality and yield of the end product (e.g. ash content, yield, baking quality etc.).
  • the expected Quality and yield of the end product e.g. ash content, yield, baking quality etc.
  • the grinding properties of the starting material are fundamental to the grinding process. Since the grinding system typically has to be regulated by the head miller, the head miller also has a decisive influence on and control of the characteristics of the flour produced. It starts with the choice of the wheat class, which can refer to the market class as well as the production location or region of the wheat, in order to influence certain grain attributes, such as a certain protein area.
  • the miller also controls the wheat blend / grists that is put into the grinding plant. The miller can also adjust the mill flow, roll speed, Speed differentials, distribution of fluted rolls, e.g.
  • the miller has further control options in combination with sieving and cleaning and finally in the maelstrom selection for mixing the final flour produced. All of these parameters and control options are used by the miller to consistently produce a flour of a certain quality.
  • grinding rollers in particular such as those used in grain milling, require constant monitoring. Apart from the optimization of production and the characteristics of the end product, it can also happen, for example, that a so-called dry run, build-up in the control system or other operational anomalies occur. If an abnormal condition lasts too long, the temperature of the grinding roller, for example, can rise to a critical level and possibly cause a fire or damage to the rollers.
  • operational anomalies can also influence the optimal operation of the system differently, in particular the quality, yield or energy consumption.
  • grinding plants are at least partially automated in many areas, current systems for automatic control and optimized operation are difficult to automate. In the prior art, mill systems are therefore often still set manually by the operating personnel based on their empirical values.
  • PLC programmable logic controller
  • GUI graphical user interface
  • the result may be reduced for the mill, for example due to a lower yield of light-colored flours or similar attempts to replace the head miller with processor-based control devices, that the complex knowledge and experience of the head miller could not simply be automated by means of rule-controlled devices, in particular not by means of autonomous, self-sufficient control devices that get by without regular routine human intervention.

  • Beater mills are also known. Impact mills are suitable, for example, for grinding a wide variety of products in grain mills (grain and by-products of the grinding), animal feed factories (animal feed, pulses), breweries (fine meal production for mash filtration), oil mills (extraction meal and crushed oil cake) or even pasta factories (pasta waste).

  • groats cut oat kernels
  • the operation of the grinding devices is influenced by a large number of parameters, such as the selection of the type of grain or the grain mixture and the cultivation area, the harvest time, the desired quality criteria, the specific weight and / or the moisture of the individual grain types or the grain mixture proportions, the air temperature, the relative humidity, the technical data of the system elements used in the mill system and / or the desired flour quality as specified process variables and the selection of the distance, the grinding pressure, the temperature and / or the power consumption of the motors of the grinding rollers, the flow rate and / or the achieved moisture of the ground material and / or the quality of the flour with regard to the mixture proportions, which Sufficiently differentiated control of the grinding process in the grain mill systems is difficult.

This change can take place both manually and fully automatically with the aid of a computer and / or a control, for example a PLC control (self-programmable control) or a PLC control (programable logic control) (regulating device).
  • the other monitored parameters can be assigned physical, technological or process-related limits as boundary conditions to be complied with. The additional monitoring of such boundary conditions can lead to an improvement in the control behavior and to a better product quality of the end products.
  • the grinding system 1 is regulated by an intelligent, self-adaptive regulation and control device 4 with self-optimized control of the mill system 1 and the grinding line of a roller system of the mill system 1.
