Monitoring Parameters and Optimizing the Technological Process in the Grinding Machine
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe paper describes the concept of a new diagnostic system for a grinding machine for feed ingredients, waste in recycling and similar use. Early diagnosis of grinding head can protect the machine's drive system from damage. So the work is of great practical importance. In the literature, there are many examples of diagnostic systems whose research ends with simulations based on data found in the bibliography. In this case, the Authors went further and developed a relatively low-complexity solution, which they tested in a real system, i.e. in a machine working in a normal production cycle. This is an advantage of the new solution in a research sense, and it makes its own contribution to the field, so the results of the research should be published.
Despite the above advantages, I do not recommend the work for publication and the form presented, but to complete it and then publish it. Reviews the form contains some informational deficiencies, editing and descriptive errors - the correction of which will improve Scientific Soundness.
In addition to the previously described linguistic remarks and the description of the background of the research in the Introduction - the weaker side of the work is: the information contained in the Abstract is inconsistent, the absence of supporting data for the work described in Chapter 4 - which makes it impossible to verify and evaluate it, the missing critical evaluation of the proposed solution in the Conclusions.
I did not notice any significant methodological errors in the work, but I suggest supplementing it to the scope described below.
Reading the Abstract, the user is not sure what was the goal of the research: the development of a new method or the design of a device. The purpose of the work must be clear and highlighted.
Please specify: when was the structure shown in Figure 1 made or bought, and include a brief description of it. The Hosokawa Alpine AG home page [10] cited in line 82 does not provide a description of the concept.
Please describe how the accelerometer amplifiers are powered and connected to the PA 16000D module, and how the measured signal is transmitted. In the literature [12] at https://www.ects.pl/ one cannot find a description of the PA 16000D module conditioning system mentioned in line 134 of the paper. An attempt to search for the phrase 'PA 16000D' ends with the message 'Search Results for “PA 16000D” No results found'.
The conclusion in lines 337-339 is too far-fetched and he is not supported by the content of the work. Therefore, it is not believable at this stage of the evaluation. Since "the prototype of low-cost device was mounted directly on the grinder's 339 body" (lines 337-341) - please include in the work clear photos of this device during its working. Because only such a view allows you to confirm the development and evaluate its operating safety. Grinding and chopping processes are accompanied by dust and pollination of the production hall. Such dust can be flammable. The working machine contains rotating components, hence an accidental breakage of the drive belt can damage the signal and power cables, which can cause electrical shorts or sparks. The picture shown in Figure 13 is not a complete view of the installed system, it is not even a view of a prototype as the caption under the drawing suggests - it is just a hand-drawn conceptual draft. There is still a long way to go from such a sketch to a construction prototype, and especially a technological prototype - that is, a fully functional and safe industrial solution. Therefore, I ask for clear photos of the work and how the developed device is mounted on the body of the grinder.
The user/operator of an grinding machine during exploitation needs data on the percentage wearing of the pins - that is, binary information: already replace/regenerate the grinding head or it is still allowed to work. The hallmarks of such pre-operational visualization of measurement results are provided in lines 348-351 of the paper and in Figure 13. It was described in these lines that the illumination of a red LED in the system indicates that the wear threshold of the pins has been exceeded. However, the paper does not describe either the implementation system of the signaling system or its detailed electronic schematic. The work does not describe the methodology and power system structure of the entire device. Please complete the work in this area.
I propose in Conclusions to add a critical evaluation of the proposed solution - that is, to list its strengths and weaknesses. Such a comparison would have to be related to other practically applied solutions. In a research paper, the presence of disadvantages or limitations of a new concept/solution does not reduce the value/quality of the research paper. Research results can be positive and negative, it is important to be aware of these limitations.
Comments on the Quality of English LanguageThe language of the work is correct to understand its essence.
However, in the body of the work there are some simplifications, inadequate forms and errors of technical language.
Sometimes used mental abbreviations lead to captions for drawings that contradict the facts, this applies to Figures 4 and 13. In Figure 13 there is a concept diagram of the monitoring system - it is not any prototype or even a view of the prototype.
Some sentences are too long (e.g., in lines 200-205), which makes them less readable and understandable.
In the body of the work, the listings are formatted incorrectly, such as on page 6 or in the captions of the figures. A list is a sentence, it begins with a capital letter, inside it there are list members separated by commas or semicolons, the list/sentence ends with a final period. There is no need to write list components with a capital letter, unless they are proper names.
In my opinion, the module shown in Figure 3 and in the text of the paper (line 134) is not a “handyscop” [13]. It is a kind of 4-channel oscilloscope and there is no need to create a new name for the instrument family. It is not a handheld instrument, since it requires a USB connection to the oscilloscope. The name "handyscop" does not commonly exist in branch nomenclature. The manufacturer of the instrument gave it the proper name of a particular model "Handyscope HS4" for commercial purposes, but it is not a category name for measuring instruments.
I also recommend that you specify the dimension/jdnostics for the parameter K2 (used in lines 186-190), that is, for the gain of the conditioning system. In the present state, the correctness of Equation 1 and the other equations cannot be verified.
The IE-PE/KS74B/KS80/KS81 accelerometer mentioned in the work text (in lines 136-139) is not a two-wire module. At least 3 wires are used for handling. The 4-pin connector of this accelerometer contains 4 pins: 1 - Signal ground, 2 - Unused, 3 - Signal output and 4 - Case. The Case pad has an important shielding function when transmitting weak AC signals under industrial noise environment.
The title of the article is too wide in relation to the scope of described research. The research was dealing with "monitoring parameters in the grinding machine" - but in the body of the paper little space was dedicated to "optimizing the technological process."
I suggest reading the text in detail again and in some cases correcting the wording precision.

Reviewer 3 Report
Comments and Suggestions for AuthorsThis paper investigates the operating parameters of a biomaterial pin grinder, specifically the issue of monitoring pin wear. The study explored the wear process of unheated and heat-treated pins through vibration analysis, and proposed a low-cost monitoring device prototype based on ESP32 and MPU6050. The paper has a clear structure, reasonable experimental design, detailed data analysis, and has certain innovation and practical value. However, the paper still has room for improvement in the following aspects:
1. In section 1: While the introduction provides a good overview of the research background, particularly concerning the issue of needle wear during the grinding of biomaterials, it could be enhanced to include more recent studies and advancements in the field. This would help to better situate the current research within the broader context of existing literature and highlight its contribution to the field.
2. In section 2.1: The article mentions the composition of feed yeast (e.g. silicon content, protein, etc.), but does not clearly state how these components affect the grinding process, pin wear or vibration characteristics. It is recommended to further discuss the impact of the physical and chemical properties of feed yeast on the experimental results and explain the reasons for selecting this specific material.
3. In section 4: The proposed monitoring device is an interesting addition, but the paper could benefit from a more detailed discussion on the practical implementation of the device. For example, how will the device be integrated into the existing grinder system? Additionally, it would be helpful to include some preliminary results or validation data from the prototype device.
4. In the conclusion: The conclusion effectively summarizes the key findings of the study. However, it could be strengthened by exploring the limitations of the study and the future research directions. In this way the paper would provide a more balanced view of the study's applicability and offer valuable insights for further advancements in the field.
