Abstract

The invention relates to a vertical roll grinder and a vertical roll grinder grinding disc material layer stabilizing device. The vertical roll grinder comprises a grinding disc, a middle shell, grinder rolls and a central feeding articulated chute, and a grinding disc liner plate is installed on the grinding disc; the vertical roll grinder grinding disc material layer stabilizing device comprises supporting plates welded to the middle shell, connecting profile steel with long holes is welded to the supporting plates, material laying frames are installed on the connecting profile steel, the front ends of the material laying frames are provided with arc-shaped material laying plates, and the bottom faces of the arc-shaped material laying plates are perpendicular to the axis of the vertical roll grinder. The vertical roll grinder grinding disc material layer stabilizing device and the vertical roll grinder have the advantages that the thickness of the material layer can be effectively controlled, and the exhausting and pre-bulking effects can be achieved on materials between two main rolls.

Description

technical field [0001] The invention belongs to the technical field of grinding equipment used in the cement industry, and in particular relates to a material layer stabilizing device for a vertical roller mill and a vertical roller mill. Background technique [0002] Vertical mill is an energy-saving grinding equipment widely used in cement, electric power, steel and other industries. During the operation of the vertical mill, the granular material is fed from the central feeding chute directly above the grinding disc, and the material falls on the center of the grinding disc. As the grinding disc rotates, the material is subjected to the action of centrifugal force and moves to the surroundings of the grinding disc in a spiral shape and enters the grinding area. Under the action of the crank arm linkage mechanism, the grinding roller exerts a downward positive pressure on the material in the grinding area to grind the material. However, some materials will not enter the ...
