For movement and distribution of the concentrated forages in animal husbandry cable and scraper conveyors with cablewasher or chainwasher working body widely are used. Considering bigger traction ability of cable in comparison with the chain, the first working body has essential advantages. Wearing of washers and formation of material blocking belongs to shortcomings of the specified working bodies against moving washer. If the first defect can be eliminated only by corresponding materials use, decrease of contacting surfaces roughness, etc. (manufacturing techniques improvement), the second defect can be eliminated by washer design optimizing. For optimization of cable scraper conveyor working body design of continuous action with 50 mm internal diameter of experimental installation was used. The article provides the technique of performance and pipeline transporting feed energy ratio determining. The article gives the results of comparative experimental researches of conveyor with cable-collar and cable-bowl mechanism. The article shows the expressions describing the performance of conveyor and energy ratio transportation, depending on the working body design, step of scraper elements installation and the length of the loading area. The graphs describing two-dimensional surface response of device performance and energy transportation are provided. On the basis of the received results analysis the conveyor parameters are proved: the volume of the bowl 0.1-0.15 cm 3 step installation of scraper elements (bowls) 0.1-0.15 m, the length of the loading area of 0.2 m and the speed of the body 0.6-0.8 m/s.conveyortransportationfriablematerialsfodderproductivityконвейертранспортированиесыпучиематериалыкормапроизводительность[Сыроватка, В.
