Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 As shown, a bulk material processing device for metallurgical pellets of the present invention is characterized in that it includes an aggregate belt conveyor 1, and a bulk material buffer storehouse 2 arranged below the aggregate belt conveyor 1 is arranged in this bulk material buffer The bypass discharge pipe on the side of the warehouse 2, the bypass electro-hydraulic flat gate valve 3 on the bypass discharge pipe, the electro-hydraulic sector gate 4 below the bypass electro-hydraulic flat gate valve 3, when When the electro-hydraulic fan gate is overhauled, the electro-hydraulic flat gate valve can cut off the material flow. The electro-hydraulic flat gate valve 5 located at the bottom of the bulk material buffer bin 2 can cut off the material flow when the closed vibrating feeder and the cone mill are overhauled. . The closed vibrating feede...

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...
