Iron concentrate storage and transportation system

Abstract

The invention belongs to the technical field of solid bulk material stockpiling, and in particular, relates to an iron concentrate storage and transportation system. The iron concentrate storage and transportation system is characterized by comprising a roof arranged above a stock heap, a railway rail arranged beside the stock heap, a set of train carriages serially connected to the railway rail,a set of belt conveyors arranged in the length direction of the stock heap in sequence at equal intervals, an elevated belt conveyor arranged on one side of the stock heap and parallel to the length direction of the stock heap, a concentrate lifting system arranged above the stock heap, and a concentrate truck loading system arranged beside the stock heap. Materials are fed into multiple feed hoppers of the elevated belt conveyor through multiple grab bridge cranes, are fed into a cantilever truck loading belt conveyor through an ore leaking car of the elevated belt conveyor, and are finally fed into a train, so that the whole piled materials can be used for piling and taking, and the effective capacity of a stock dump is greatly improved; and a front loader is not needed to take and loadthe materials, so that the equipment maintenance cost and the labor cost are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of solid bulk storage, and in particular relates to an iron concentrate storage and transportation system. Background technique [0002] Due to its fine particle size and water content, especially some low-grade iron concentrates also contain some slime, the general iron concentrate presents a characteristic of fineness, water content and mud content. Bulk materials of this nature are easily blocked inside the ore bin and at the discharge port when they are stored in the ore bin, so generally iron concentrates are rarely stored in the ore bin but in the ore pile. When the ore pile is used for storage, in order to prevent the blockage of the discharge port, the general ore pile has no more than three discharge ports, in case there are too many discharge ports, and a single discharge port does not work for a long time, resulting in mineral compaction and blockage of the discharge port. Feed opening, and too f...

AI Technical Summary

Problems solved by technology

When the ore pile is used for storage, in order to prevent the blockage of the discharge port, the general ore pile has no more than three discharge ports, in case there are too many discharge ports, and a single discharge port does not work for a long time, resulting in mineral hardening and blockage. The material opening, and too few discharge openings greatly reduce the effective volume of the entire ore heap, reducing the effective ore storage capacity of the ore heap

In order to prevent blockage and increase the effective volume of ore piles, many mines, especially mines transported by rail, adopt front-loading machine loading. However, the way of front-loading machine loading has problems such as excessive loading machinery and manpower consumption, and high loading costs. Moreover, in order to facilitate the entrance and exit of the front-loading machine, most of this method does not have a roof, so that the iron concentrate will be wet in rainy days, thereby greatly increasing the moisture content of the iron concentrate powder and increasing the energy consumption of subsequent pelletizing or sintering operations.
