Anti-segregation ore-blending system of high-pressure roller mill

Abstract

The invention belongs to the technical field of mineral separation in mines, and in particular relates to an anti-segregation ore-blending system of a high-pressure roller mill. The system is characterized by comprising a distributing-blending system, an aggregate conveying sealing-tape machine and a stirring system, wherein the distributing-blending system comprises a raw material cabin, an oversize return cabin, a raw material cabin chute, an oversize return cabin chute, a pneumatic valve on an outlet of the raw material cabin chute and the oversize return cabin chute, a discharging sealing-tape machine I, a discharging sealing-tape machine II, and a head funnel on a junction of the discharging sealing-tape machine I and the discharging sealing-tape machine II, and the aggregate conveying sealing-tape machine is arranged below the outlet of the head funnel. New materials and oversize returned materials are respectively fed into the raw material cabin and the oversize return cabin, and the pneumatic valve is used for controlling the mixing proportion of the new materials and the oversize returned materials according to the granularity and the ore properties of the new materials and the oversize returned materials to realize reasonable ore-blending, so that the material segregation caused by the condition that the new material and the oversize returned material are fed into the same cabin is avoided, and the continuity and the stability of feeding of the high-pressure roller mill can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mine beneficiation, and in particular relates to a high-pressure roller mill anti-segregation ore mixing system. Background technique [0002] The high-pressure roller mill was designed by Professor Schoenert of Germany in the 1980s. It uses the principle of laminated crushing to crush materials under static pressure. It is a double-roller crushing equipment that has been widely used in the field of metallurgy and mining in recent years. At present, the commonly used process is the closed-circuit process of the high-pressure roller mill, that is, a coarse vibrating screen is arranged after the high-pressure roller mill, and the products of the high-pressure roller mill are classified. material. When the high-pressure roller mill is working, it must be ensured that the gap between the two rollers is filled with materials, and the particle size distribution in the direction of the roller width cannot be to...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-pressure roller mill anti-segregation ore blending system to solve the problem of segregation of new materials and returned materials on the screen in the ore bin and belt transportation process in the closed-circuit process of high-pressure roller mill screening
