Mathematical modelling applied to batch milling (at experimental level), is a very important tool to simulate and predict the granulometric yield of a given treated ore; this means, for a given duration of milling operation, to obtain an estimate of the corresponding granulometric analysis, which can then be tested with real data later on, to verify the estimates. The model involves the selection and fracture functions depending on each mesh size in the ore distribution. This will allow the prediction of effective and reliable results, saving costs and more importantly, time, without the need to perform the milling process for each prediction of batch milling.

In the present work we perform the systematic study, employing X-ray diffraction and Mössbauer spectrometry, of the variation of the structural and hyperfine parameters during the milling process of the icosahedral Al64Cu23Fe13 quasicrystal. For this purpose, the samples were prepared by arc-furnace technique followed by heat treatment. Then, the samples were nanoestructured in a high energy ball milling equipment during 5, 10, 15, 20, 45, 50 and 60 hours. The X-ray diffraction patterns show the stability of the nanoestructured samples. Furthermore, the Mössbauer spectra indicate the increase of the Fe-sites in the grain boundary during the milling process.

We propose a process for making a nutraceutical beverage, from camu camu, which strengthens the immune system through their high levels of vitamins, essential amino acids and minerals. This process involves the primary treatment unit operations such as selection, sorting, bleaching, pulping, pulp refining and pulp pasteurization of camu camu. It has managed to drink, preserving all its nutritional properties. The report analyzes the drinking 1334 mg ascorbic acid / 100 ml and 197.90 ppm levels of calcium: magnesium 47.27 ppm to 1.24 ppm of Zn and energy 66.38 calories per 100 ml.

The main objective of this research was to show the predictive model implementation effects adjusted to grinding process on the economic profitability of a rice milling company. In first instance, quality and production area database was used to model a multiple regression equation, using the “Step by Step” technique in Minitab 19, resulting in: Actual Performance = 0.001 + 0.9317Hest Analysis - 0.000339 Processed Sacks; Predictive R2 = 95.81% and PRESS = 47.5168; concluding that the model fits the process, it is significant and has good predictive capacity. The regression equation was then simulated with Monte Carlo by analyzing probabilities and ranges in MS-Excel, earning operational revenue amounting to S/. 3,263,787.74 corresponding to an improvement of 3.94% compared to 2019, thus improving the company's economic profitability to 9.34% in Net Profit Margin and 15.92% in the ROA...

En este estudio, se examinó el proceso de pilado de arroz, para aumentar la productividad. Este análisis implicó evaluar la situación actual de la empresa, donde se identificaron los indicadores relacionados con la productividad, producción y la eficiencia en el uso de la materia prima. La productividad global se estimó en 0,207 sacos de arroz pilado/soles. Se determinó las distintas etapas, utilizando un diagrama de análisis del proceso. Se identificó el cuello de botella, que era la etapa de secado, que se realiza de forma artesanal y requería un tiempo de 2,49 minutos/ sacos de arroz pilado; con una eficiencia física del 57,23%. Además, la falta de mantenimiento preventivo ocasionó un total de 127 interrupciones en la producción en 2022. Para ello, se propuso un nuevo método de secado, que implicaba la adquisición de tecnología moderna, que funciona mediante un flujo ...

This study was performed in an agro-industrial milling company with the aim of reducing operative costs over the production and manteinance areas. The company's data was obtained through an interview and documentary analysis. Initial diagnosis was made using the following methods: SWOT analysis, Porter's five forces, PESTLE analysis, IFE and EFE Matrix, Ishikawa diagram and Pareto chart. An improvement plan was designed including tools related to Production Management and Manteinance Management: Demand Forecasting, MRP, Preventing Manteinance Plan, Transport network optimization, SRM and Process Standarizing. The improvement plan was simulated in ProModel 2016 software, using projected production data from the development of the proposed tools. Results obtained were: removal of rate of unscheduled plant shutdown, 14% decreased of the production rate not achieved by the machine "Table Pad...

In all mining operations, a reconciliation system is necessary, which allows measuring the performance of the processes involved in obtaining the final product, from the reserve-resource models, through mine design, mine planning, mining production, until culminating in the metallurgical process. It is through the relationship between the ore received (ground ore) with the ore sent to grinding (short-term model), that reconciliation factors will result for tonnage, grade and metal. Subsequently, they will be evaluated in a monthly, quarterly and / or annual period of time, and will help to refine the processes and sub-processes of the short-term model, as well as the mining process and the metallurgical process. The results will be reflected in the reduction of the differences in the reconciliation factors for tonnage, grade and metal, this reduction must be supported over time; In other...

This research job will describe each of the activities preformed at the company “Molino ABC” with the purpose of designing, evaluate and implement an estimated cost structure and stablish an improvement plan to increase profitability. The milling company, specifically the production of wheat flour, have certain difficulties, such as some of the manufacturing industries, to obtain a determination of estimated costs in line for the decision-making of managers, such as: management bulk inventories of wheat and the diversity of products and by-products obtained from the same raw material (wheat). In the first chapter, a brief description of the milling company and the sector is made. Additionally, an approach of the problem is made based in the indicators that are deviated from the objectives that the organization had established, such as the level of profitability at the product level. ...

The aim of this study was to determinate the isozymic characteristic of six Annona cherimola populations from La Libertad Region. Leaves of trees with at least two fructifications were collected in six localities: La Cuesta, Paday, Samne, Cascas, Poroto and Trujillo. The samples were processed and the electrophoretic profiles of the enzymes PGI, APCH, MDH and ME were analyzed. We found polymorphism for the loci PGI-1 and ME, with seven and two alleles respectively, average values of 0,40 for polymorphism and mean heterozygosity between 0,206 (La Cuesta) and 0,285 (Poroto). There is high phenotypic and genotypic variability in six Annona cherimola populations in La Libertad Region.
