In the article the problem of determining the nominal size of real particles of grain materials, which significantly affect the technological parameters of the hoppers and their design parameters. Are specific correction factors for sredenegeometricheskogo razsmera nektoryh ubiquitous forms particles loose body.

This article provides an analytical solution to determine the forming wall slot hopper highest possible throughput with vertical end stenkmi among all bins have the same inlet and outlet openings. These bins are designed for hydraulic type expiration of the bulk material. They are evenly distributed granular body as it exits from the outlet and reduce the degree of influence on the flow characteristics of the vaults of the hopper.

Keywords: bunker, loose body, bunker form, friction, outlets, bunker expense.

In this paper, a comparative analysis of the shift parameter distribution initial set of calculated analytical method and simulated, obtained by computer simulation using sample data. Error δi shifts between the parameters listed in the table and plotted errors on the scope and volume of the aggregate.
Thus, increasing the volume of the aggregate error is reduced from 30% to 1% at a constant volume sample m = 50.
Keywords: sampling, aggregate, volume, range, accuracy, distribution, performance analysis, engineering, reliability.
