Ore blending system and method in slurry pipeline conveying system

Abstract

The invention provides an ore blending system and method. The ore blending system comprises a first conveying belt, a second conveying belt, a first metering device, a second metering device and a third conveying belt. The discharging end of the first conveying belt and the discharging end of the second conveying belt are located over the third conveying belt, the first metering device is arranged on the first conveying belt and used for metering ore quantity conveyed by the first conveying belt in real time, the second metering device is arragned o the second conveying belt and used for metering ore quantity conveyed by the second conveying belt in real, and the ore quantity conveyed by the first conveying belt and the ore quantity conveyed by the second conveying belt are set according to the metering values of the first metering device and the second metering device and conveyed to the third conveying belt according to the preset ore blending ratio. According to the ore blending system and method, the belt conveying system based on accurate metering is adopted, accurate matching of different regions and ore with different qualities is achieved, the ore blending cost and environmental pollution are reduced, and sustainable development of economy and environment is achieved.

Description

technical field [0001] The invention relates to the technical field of mineral proportioning, in particular to an ore mixing system and an ore mixing method for minerals of different grades in the field of slurry pipeline transportation. Background technique [0002] With the rapid economic growth of our country, especially the sustained and stable development of metallurgy, petrochemical, petroleum, chemical fertilizer and other industries in recent years, with the increase in energy prices, transportation costs have become higher and higher, and the use of hydraulic pipelines to transport solid materials, Compared with other transportation (such as railways and highways), it has short transportation distance, low investment in infrastructure, adapts to terrain and can use height difference potential energy, does not occupy or occupy less land, does not pollute the environment and is not disturbed by external conditions, and can realize Continuous operation, reliable techno...

Problems solved by technology

Currently, the most widely used method of using hydraulic pipelines to transport solid materials is to use pipelines to transport mineral ore slurry. Before using pipelines to transport mineral ore slurry, it is necessary to mix a variety of minerals of different grades and regions according to predetermined proportions. For example, from Dahongshan, Yunnan The amount of iron ore is large, and it needs to be mixed with the ore and relatively low-grade minerals transported by another pipeline according to a predetermined ratio. , Different grades of minerals are transported to the same stockyard, and then the specific ore blending is carried out in the stockyard. With the continuous increase of the application of the slurry pipeline transportation system, the existing ore blending method has the following defects: centralized blending The stockyard of the mine needs to stack minerals of different grades at the same time, which requires a large space and will cause a lot of pollution and waste, thus greatly increasing the production cost
