Abstract

The present invention relates to a raw material charging device and a charging method and, more particularly, to a raw material charging device and a charging method, which can successively stack raw materials on a sintering truck in the descending order of particle size, thereby improving the air permeability of the raw materials. A raw material charging device according to an embodiment of the present invention comprises: a raw material supply unit for discharging charged raw materials; a storage unit spaced from the raw material supply unit and configured to store the raw materials discharged from the raw material supply unit; and a charging chute forming a transfer path between the raw material supply unit and the storage unit and having a vibration surface formed such that the dimensionless acceleration (a) of the raw materials, which move on the transfer path, have a value of 8 or larger.

Description

technical field [0001] The present invention relates to a raw material loading device and a loading method, and more particularly, to a raw material loading device and a loading method for loading raw materials into a sintering trolley. Background technique [0002] Generally, in a sintering process, sintering raw materials are loaded into a sintering trolley of a sintering machine by using a loading device to produce sintered ore. [0003] figure 1 General equipment for loading sinter feedstock is shown. The apparatus includes: a sintering raw material hopper 2 storing a sintering raw material 1 in which pulverized iron ore, auxiliary raw materials such as limestone, and coke powder as a fuel are mixed with each other; a raw material supply device, the raw material supply device Consists of a drum feeder 3 configured to supply sintering raw material downward through a hopper gate 4 of a sintering raw material hopper 2 via which it rotates; and a charging chute 5 configure...
