Pelletizing disc feeding disperser

Abstract

The invention relates to a feeding disperser of a balling pan, which belongs to the technical field of ore balling technique. A U-shaped steel support rack is made, a plurality of round holes are arranged at the two side walls of the support rack, smooth and wearproof steel sticks are arranged on the round holes, grooves are opened at the head parts of the two ends of each stick, the two ends of the sticks are sealed by a solid protection cover, a sliding arm is fixed on the protection cover by a bolt at each position that aligns at the grooves, the free end of the sliding arm is positioned in the groove that is poisoned at the head of the stick so as to ensure that the stick can roll only and can not slide between the side walls of the support rack. The feeding disperser has the advantages that a part of ore powders drop into the balling pan from a clearance of the sticks during the rolling process on the disperser and the ore powders that can not drop into the balling pan from the upper clearance drop into the balling pan from the lower clearance, thereby enlarging the dropping area of the ore powders, at the same time, the clumpy ore powders can be crushed due to the vibration of the disperser, thereby improving the dispersion degree of the ore powders, enlarging the contact area between the greenballs and the ore powders and improving the rolling and balling quality of thegreenballs.

Description

technical field [0001] The invention belongs to the technical field of ore pelletizing, and in particular provides a pelletizing disk feeding disperser, which is suitable for pelletizing disks used in pelletizing ore production. Background technique [0002] Pellets are one of the main raw materials for blast furnace smelting. The production of pellets requires pelletizing the concentrate powder first, and then roasting. Pelletization is the primary process of pellet production, and the quality of pelletization will affect the quality of subsequent processes and finished pellets. In addition to the properties of the raw material itself and the parameters of the pelletizing disk, the feeding method of the pelletizing disk also affects the pelletizing quality. At present, most of the pelletizing disc feeders in domestic pelletizing plants are belts, and the width of the belt is relatively narrow. Iron ore powder for pelletizing falls directly into the pelletizing disc from th...

Problems solved by technology

[0003] The purpose of the present invention is to provide a feed disperser for pelletizing discs, which overcomes the problem of falling into the screening system with the grown raw pellets before they are formed into pellets in the prior art, increasing the load and return amount of the screening system, The problem that the rolling quality of raw balls is reduced
