Abstract

The invention discloses a vertical roller mill with material prepressing and positioned blanking and a vertical roller milling method. A material layer prepressing device and a concentrated blanking device are arranged in an inner cavity of a mill body; the material layer prepressing device includes a grinding roller; rotating shafts are arranged at two ends of the grinding roller, and are connected with connecting rods through bearings and bearing bases; the connecting rods are connected with a support frame; the support frame is fixed on the wall of the inner cavity of the mill body, and is positioned two adjacent grinding rollers in the inner cavity of the mill body; the upper end of an extension pipe of the concentrated blanking device is connected with the lower end of a blanking inner cone hopper; the lower part of a fixed plate at the lower part of an inner cavity of the extension pipe is connected with the upper part of a connecting plate; the lower part of the connecting plate is connected with a scraper; and a gap is formed between the lower end surface of the scraper and the upper end surface of a milling disc. The vertical roller mill is reasonable in design, accurate in blanking point and excellent in material paving and prepressing effects, and can improve the powder milling quality.

Description

Technical field:

[0001] The invention relates to a roller mill method for reusing industrial steel slag, in particular to a vertical roller mill with pre-pressed materials and positioning blanking and a vertical roller mill method. Background technique:

[0002] Vertical roller mill is an important grinding equipment in the field of grinding technology. It is required to evenly scatter the material on the grinding disc and grind it under the rolling of the grinding roller. The problems existing in the traditional slag powder production line project are mainly reflected in: 1. The material is transported through the chute along the wall of the inner cone to the cone mouth of the inner cone and falls to the grinding table. The inner wall of the chute is directly opposite, and then rebounds slightly and falls to the grinding table, that is, the material does not fall to the center of the grinding table, so segregation inevitably occurs during the falling process of the material...
