Architectural high-pressure ore roller mill

Abstract

The invention discloses an architectural high-pressure ore roller mill which comprises a rack, a roller milling chamber, a first high-pressure roller, a second high-pressure roller, a hydraulic driving device, a material scattering chamber, a discharging inclined tube, a scattering device and a recycling and crushing device, wherein the roller milling chamber is formed in the rack; the first and second high-pressure rollers are arranged in the roller milling chamber; the hydraulic driving device is used for driving the first and second high-pressure rollers to be close to each other so as to extrude and crush the materials; the material scattering chamber is formed in the side of the roller milling chamber; the discharging inclined tube is arranged on the lower part of the roller milling chamber and penetrates into the material scattering chamber from the side part of the material scattering chamber; the scattering device is arranged in the material scattering chamber; the outlet of the discharging inclined tube is positioned above the scattering device; and the recycling and crushing device is used for screening large-particle materials and performing secondary crushing. Accordingto the roller mill disclosed by the invention, operations of crushing, scattering, screening and recycling can be directly performed in the same equipment, so that the time of conveying the materialsamong corresponding pieces of equipment at various links is effectively shortened, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a high-pressure ore roller mill for construction. Background technique [0002] High-pressure roller mills are widely used in the crushing of ore in cement raw materials in the construction industry. Since the high-pressure roller mill implements quasi-static pressure crushing, this quasi-static pressure crushing method saves energy consumption compared with the impact crushing method, and the crushing effect is better, and the wear of the rollers is also smaller. But in this way, the pulverized ore will be caked and agglomerated due to the effect of high pressure. In the traditional way, the caked material is discharged from the high-pressure roller mill and transported to another equipment by cart. The frozen reclaimed material is broken up, and then transported manually or by tools to the filtering equipment for filtering operation to obtain materials with composite spec...

AI Technical Summary

Problems solved by technology

Materials that do not meet the specifications are manually pushed back to the high-pressure roller mill for secondary crushing, which has low work efficiency, high equipment investment costs, large floor space, and low space utilization.
