Bulk cargo treatment device and method for metallurgy pellets

Abstract

The invention relates to a bulk cargo treatment device and method for metallurgy pellets. The bulk cargo treatment device is characterized by comprising an aggregate sealing-tape machine, a bulk cargo buffering cabin, a bypass electrohydraulic flat gate valve, an electrohydraulic sector gate, an under-cabin electrohydraulic flat gate valve, a sealed type vibration feeding machine, a cone mill, a burying scraper, a bucket elevator and a finished-product sealing-tape machine. Bulk cargoes are conveyed into the bulk cargo buffering cabin by the aggregate sealing-tape machine and then are fed into the sealed type vibration feeding machine by the under-cabin electrohydraulic flat gate valve; the sealed type vibration feeding machine is used for feeding the bulk cargoes into the cone mill; the burying scraper is used for conveying a finished-product material to the finished-product sealing-tape machine by the bucket elevator; the finished-product sealing-tape machine is used for conveying the finished-product material to a mixing system to be pelletized again. According to the bulk cargo treatment device and method for the metallurgy pellets, the granularity and the quality of prepared pellet bulk cargoes are improved effectively and the pelletizing is easy to carry out again. The pelletized can be recovered within short time and considerable economic benefits are created.

Description

technical field [0001] The invention relates to the technical field of bulk material processing in the production process of metallurgical pellets, in particular to a bulk material processing device and method for metallurgical pellets. Background technique [0002] At present, the pelletizing plants in our country use the grate machine-rotary kiln process, and there are two kinds of return materials in this process. The first is raw ball return; this kind of return is not roasted, and it will be broken after being stirred in the mixer, and has no effect on pelleting. The second is the return material of the return section of the grate machine head; it is this part of the material that has the greatest impact on pelletizing, and there are two types of this part of the material: the ash from the ash box of the chain grate machine and the ball leaked from the head of the chain grate machine. The particle size of the ash is very fine, which does not affect the ball making. The...

Problems solved by technology

In the past, for iron and steel complexes, the only way to make use of it was to sell the returned ore pellets to the sintering plant at a low price. The cost of long-distance transportation, the company's benefits will be affected to a certain extent, so it is not economical to use this method
