Annotation

In the structure of the product's production, feed is in the first place and accounts for 60-70% of the total cost. The effectiveness of stagnation of concentrated feed depends on the quality of their preparation, and the uniformity of detail and type of fractional stock of animal husbandry products.
In the midst of all the development of methods of refinement and design solutions for the greatest expansion for the refinement of feed grain, hammer mills have emerged, which, unlike any other in the world, provide energy saving, with fine grinding up to 40% of the saw-like fraction, and for coarse grains - up to 20% of whole and incomplete grains. At the same time, disk-type grain trimming designs are becoming more and more widespread in the world. Such structures are developed from hammer construction with lower energy consumption and higher yield of the finished product. Therefore, further research aimed at improving the efficiency of the work of disk workers is relevant.
Experimental studies of disk grain processing were carried out based on the theoretical design of the experiment, which was why mathematical models of processes were selected in the form of regression. The factors in the experiment were the frequency of disk wrapping n (x1), the modular gap between the disks m (x2) and the moisture content of the grain W (x3). Optimization criteria are the energy density of the detail q (y1) and the uniformity of k (y2). The energy intensity of the process began as a balance between effort and productivity. Uniformity began as a relationship instead of often with rational parameters to the point of importance and was expressed in hundreds.
As a result of experimental studies of disk grain processing, it has been established that the energy intensity of the process and the uniformity of the grain are dependent on all relevant factors, with which rational indicators are based on optimization criteria and do not match. The main task is to find the optimal variation of factors for two criteria, which makes it possible to confirm that the minimum energy intensity of the process is in the range q = 3.67…4.54 kW hour/t, one Particularity - k=86.5…92.6% at values of additional factors n=1260-1320 min-1; W=12.8-13.2% for a rational range of refinement steps.

Keywords: grain, detailing, parameters, efficiency, wrapping frequency, moisture content, nutritional energy content, uniformity of detailing.
