THE USE OF TUBULAR BELT CONVEYORS FOR THE INDUSTRIAL WASTE OF ENTERPRISES

Urgency of the problem. There is a critical situation in the segment of mining hoists. A traditional cable car skip hoist has almost exhausted its possibilities. The increasing depth of deposits and the productivity growth of development machines and clearing combines stipulate bigger capacities, sizes and speed of skips. This increases the power and weight of lifting machines, the number and diameter of cables, the height of the copra, and the diameter of the shaft are increased too. The search for alternative methods of mine lifting, which have a higher specific productivity is being carried out. It leads to a clear conclusion about the prospects of the transition from rope pneumatic lifting units to the skip ones. Purpose of the work: to ensure the stability of the vessel movement in the mine skip pneuvmo elevating equipment. Research methodology: to reduce the non-return energy losses on the rise of the skip’s own weight, a closed pneumatic system is organized: the outlet section of the descent pipeline is connected with the inlet window of the blower. The blower receives the flow pressure, which is determined by the weight of the empty skip, with the result that the energy consumption of the lift depends only on the weight of the mineral. The optimal operation of the closed system is possible only at a certain value of the pipeline diameter. Results. The design and operation principle of the proposed air-lifting installation are described, the method of calculating the diameter of the pipelines for the implementation of air exchange between the descents and lifting pipelines is given. Conclusion. The article substantiates the new design of the skip pneumatic lifting installation, which has a higher performance and energy efficiency. This is achieved by means of reducing the aerodynamic drag of the track and eliminating the irrevocable energy costs for the rise of its own mass of the skip. According to the method proposed, the stability of the vessel in the descent pipeline of the pneumatic lifting installation is calculated
