To the justification of the direction for improving the design of a bulk material belt dispenser

The purpose of the research is to reduce the dosing error of belt dispensers of bulk materials. The theoretical research methodology involved studying, using numerical methods, the pattern of changes in the dosing error when varying the design parameters of the dispenser and the indicators of its operating process. The preparation of composites and mixtures requires ensuring proportions between their components. Violation of proportions causes a change in the properties of the composite and/or a decrease in the quality of the mixture. The most accurate way to maintain the weight of a portion of components is with batch scale batchers. However, in this case, the energy costs for distributing the components throughout the entire volume of the prepared mixture are high. Continuous weight dosing allows you to reduce the energy consumption of mixture formation through the use of continuous mixers. The use of continuous weighing feeders requires a set of measures to improve their accuracy of adjustment to a given performance. Increasing the dosing accuracy in the event of dispenser setting errors requires improving the design of continuous belt-type dispensers in the direction of increasing the speed of the belt and compacting the material in the dosing zone. Increasing the active area of the unloading opening contributes to the possibility of increasing the speed of the belt. An increase in the height of the dosed layer on the tape helps to reduce the dosing error. When the ratio of the opening width to its height is 4, the performance error is 0.2 (20%) when adjusting the performance by window height with an error of 1 mm; with the specified ratio equal to 1, the performance error is 0.1; with the specified ratio equal to 0.5, the performance error is 0.05. Additional active working elements in the dosing zone will allow you to increase the height of the dosed layer of material.
