Embodiment Construction

[0031] In order to further understand the present invention, the preferred embodiments of the present invention are described below in conjunction with the examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0032] See Figure 2a with Figure 2b , Figure 2a The overall schematic diagram of the grinding device installed with the debris separation device provided by the present invention, Figure 2b for Figure 2a Schematic diagram of the debris separation device in . Figure 2a with Figure 2b The debris separating device in is the first embodiment provided by the present invention.

[0033] Such as Figure 2a with Figure 2b As shown, above the high-pressure roller mill 11, there is a buffer warehouse 12 for buffer materials. The purpose of the buffer warehouse 12 is to provide ore materials to the high-pressure roll...

Abstract

The invention provides a sundries separating device used in grinding ore materials, which comprises a first roller bed and a second roller bed; the first roller bed and the second roller bed respectively consist of a plurality of rollers of which the axes are parallel and which have the same rotating direction; the first roller bed and the second roller bed are respectively provided with a feed end and a discharge end; adjustable clearances are reserved between adjacent rollers in the plurality of the rollers of the first roller bed and the second roller bed; the rotating direction of the rollers of the first roller bed is opposite to that of the rollers of the second roller bed; and the first feed end and the second feed end are connected to form a feed end of the sundries separating device. Compared with the prior art, the device effectively utilizes the upper space of a surge bin while removing sundries in the ore materials, and can simultaneously remove metal sundries and non-metal sundries to avoid the sundries damaging a grinder.

Description

technical field [0001] The invention relates to a pretreatment device for ore materials, in particular to a sundry separation device used in grinding ore materials. Background technique [0002] Pellet is one of the main raw materials for blast furnace ironmaking and direct reduced iron. Pellets have several advantages over sinter. For example, the mechanical strength of pellets in the cold state is higher than that of sintered ore, so it is not easy to be broken and cracked during transportation, loading and unloading and storage, with less consumption and less powder produced, which is conducive to improving the air permeability of the blast furnace material column and making the furnace The airflow inside is evenly distributed. [0003] When preparing pellets, the ore material is crushed first to increase the specific surface area of ​​the material and reduce the particle size of the ore material, and then mix the ore material with other additives and add a certain amou...
