Analysis of features of the design of a screw feeder for the purpose of improving its work

Feeders are an integral part of the modern technological process, they establish and regulate pace production, ensure its rhythm, contribute to increased productivity increase output.
 The aim article is investigate analyze types feeders, in particular design features a screw feeder, determine advantages disadvantages. In order efficiency propose way improve based on modernization screw.
 feeders considered article, main attention paid study disadvantages feeder most common processes various industries as simplest often structural sources, which showed that issue configuration not adequately studied terms uptime factors affecting this aspect indicate relevance.
 Currently, works domestic authors industries, waste-free considered. describes detail these developed by TechTron two versions - gutter pipe. Today, there also studies conveyor with additional blades spirals screw, relationship between functional parameters established.
 An analysis existing sources has shown issues features, namely screws have been enough aspect, indicating relevance solve specific problem increasing work efficiency. (screw) compared other such continuity supply, tightness, simplicity design, ability create excess pressure at outlet aggregate equipment industrial plants, led their widespread use many processes.The disadvantage low due communication auger blade transported material, only translational motion, but rotational, leads turning material together auger. Also rapid operation loading pipe overloads.
 To eliminate one important shortcomings sensitivity overload, resulting accumulation inside chute, stopping reducing performance operational reliability, configurations were changed. Namely, advanced was divided into zones A zone, B zone screw. Such structure spiral surface cylindrical casing smaller diameter D1 than D2 feeder. follows. During bulk fills entire space under device continuous flow, including When rotated, completely filled D1, having fill factor j1 = 1, moves flow through section A. approaching B, D2, coefficient decreases j2, ensures without increases reliability.
