Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a high-pressure grinding roller device for building macadam.
Background
High-pressure roller mills are commonly used in the construction industry for the comminution of ores in cement raw materials. Because the high-pressure roller mill implements quasi-static pressure crushing, compared with an impact crushing mode, the quasi-static pressure crushing mode saves energy consumption, has better crushing effect and has smaller roller abrasion. However, in the conventional mode, the crushed ore is caked under the action of high pressure, and after the caked material is discharged out of the high-pressure roller mill, the caked material is conveyed to another device through a cart to break up the frozen material, and then the caked material is conveyed to a filtering device through manpower or tools to be filtered, so that the material with the composite specification is obtained. And traditional scattering in-process does not carry out heat treatment to the material, and when the ore was comparatively moist, the viscosity after the material was pressed by the static pressure was great to be difficult for being broken up, the effect of breaing up is relatively poor.
