Embodiment Construction

[0033] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples.

[0034] The present invention proposes a slag crushing device, the crushing device includes two or more rotatably arranged crushing wheel sets in pairs, and non-contact reversing meshing is used between two adjacent crushing wheel sets, and the crushing wheel sets have Spray structure. The invention utilizes the slag crushing device to mechanically crush the slag, and can use its water spray structure to process the slag into raw materials for making cement during the crushing.

[0035] Such as figure 1 As shown, it is a structural schematic diagram of a specific embodiment of the present invention. In this embodiment, the crushing device includes two crushing wheel sets 116, the axes of the two crushing wheel sets are parallel, but staggered up and down, and the connecting line between the centers ...

Abstract

The invention discloses a furnace slag crushing device, a crushing method and a semi-wet method furnace slag processing system. The crushing device comprises two crushing wheel groups which are arranged in a rotating way, are meshed with each other in a non-contact-type reversing way and have water spraying structure. By utilizing a water spraying mechanism to spray high pressure water out from a tooth surface to crush and cool furnace slag, thus preventing the furnace slag grains from being adhered again; the invention adopts the conception that a small quantity of water which is taken as cooling medium is combined with the mechanical crushing so as to improve the quality of byproducts of the furnace slag and the heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of slag treatment in iron and steel metallurgical processes; in particular, it refers to a slag crushing device, a crushing method and a semi-wet slag processing system with the crushing device. Background technique [0002] Iron and steel metallurgical process - blast furnace ironmaking, converter steelmaking and other processes produce a large amount of smelting slag at a rate of 30-40% of the steel output every year, with an annual output of hundreds of millions of tons globally, and the heat energy taken away by it is equivalent to standard There are more than 20 million tons of coal, equivalent to 15 billion yuan. In order to effectively consume this part of the slag and turn waste into treasure, the predecessors have done a lot of work. Among them, the most used water method is to quench the slag through water to make raw materials for cement. , thus solving the problem of whereabouts of the slag, however, the w...
