Problems solved by technology

[0007] 1) Rely on the movement of the large pellets in the disc pelletizer to hit the crushing rod, but in the actual operation process, the large pellets often stay in a certain area, the movement speed and impact force are limited, so the crushing efficiency is low;
[0008] 2) Since the qualified pellets and unqualified large pellets are mixed together in the disc pelletizer, when the above crushing device breaks the unqualified large pellets, some qualified pellets will also hit The broken blade will inevitably break some qualified pellets at the same time, so that the pelletized material needs to be shaped again, which will reduce the output of the disc pelletizer and increase the energy consumption;
[0009] The crushing mechanism is placed in the pelletizing material for a long time, and the wear and tear is relatively large

Abstract

The invention discloses a disc pelletizer and a crushing method of large pellets in the disc pelletizer, the disc pelletizer is provided with a large pellet crushing device, the large pellet crushing device comprises a rack (1), a cantilever (2) hinged to the rack (1), fixed rake teeth (3) connected with the cantilever (2), and telescopic mechanisms (14) with the two ends of movable rake teeth and driving mechanisms (8) hinged to the rack (1) and the cantilever (2) respectively; the control system is used for controlling the telescopic mechanism (14) to stretch out and draw back and the driving mechanism (8) to start and stop. The production process comprises the following steps that the number of large pellets with the diameter larger than the quality standard requirement in the disc pelletizer is detected in time, when the detected number of the large pellets reaches the allowable upper limit value of the number of the large pellets, the cantilever (2) is put down, the driving mechanism (8) is controlled to be started, and the large pellets are crushed; and after crushing is completed, the telescopic mechanism (14) shrinks, the cantilever (2) is lifted up, and the driving mechanism (8) stops running.

Description

technical field [0001] The invention relates to the technical field of disc pelletizers, in particular to a disc pelletizer with a large pellet crushing device; the invention also relates to a method for crushing large pellets in the disk pelletizer. Background technique [0002] Disc pelletizer is a kind of equipment widely used in steel, non-ferrous metallurgy, cement, fertilizer and other industrial fields. The disc pelletizing machine is used in the production of ironmaking pellets in the metallurgical industry and the pelletizing of non-ferrous metal mixed concentrates to improve the technical and economic indicators of smelting. During operation, coke powder, limestone powder (or quicklime) and iron concentrate powder are mixed in the mixer, and then input to the feeding device on the upper part of the disc pelletizer, and the feeding device is evenly fed to the pelletizer , and at the same time, spray water is supplied by the spray device. The inclined disc is rotat...
