The installed power of the electric motors on separate conveyor installations reaches 3600 ket; The speed of the tape is 6 m/s, and on rotary dumps up to 8 m/s. The length of the conveyor stations reaches 1800 m, and 4 there is a tendency to an even greater increase in their increase. The length of conveyor lines reaches 9 km. The supporting constructions of the conveyor consist of separate sections, which facilitates the installation, dismantling and movement of conveyor lines. Recently, foreign companies prefer to use conveyors on flexible frames in the form of two steel ropes stretched between two anchor mounts at large distances, which ensures the absence of vibration, silent move, better fit, lower cost, ease of installation and repair. Cruitonacular conveyors with an angle of inclination up to 45-60 ° are used abroad, and some structures are used to 90 °, which allows reducing the distance of conveyor transport. Depending on the structure of the supporting organ, the steeponacular conveyors are divided into three groups: plate, tape and bucket. The Research Institute of the Rubber Industry (NIIRP) has developed LPB and LP-600 tape with sides and partitions. Technical and economic analysis shows that the use of special ribbons with protrusions reduces the feed consumption by 16-20% by reducing the length of the installation, reduces the total cost of the conveyor by 10-15% and its weight by 12-16%.
