Vertical roller grinding machine for super-fine powder

Abstract

This invention relates to a multi-power ultrafine grinding vertical lapping machine, which comprises housing, a grinding board, a power transmitting means, an air intake duct system connecting the grinding board and charging pipe, wherein a motor and a decelerator in the lower of the grinding board constitute an actuating system, and in the grinding board is arranged a corresponding bistrique supported in the locomotive; the grinding roll of the bistrique presses to ginding board edge, and in the bistrique is arranged the grinding head motor used for driving the roll rotating; in the housing is arranged the crosswind gas flow duct channel for driving air flow upwards in housing.

Description

technical field [0001] The invention relates to a multi-power grinding superfine powder vertical roller grinding machine in which a grinding disc and a grinding roller can move independently. Background technique [0002] Most of the known vertical roller mills have a structure that the large grinding disc rotates around the central axis. The central axis is driven by the lower motor and the reducer. The grinding head and the grinding roller are driven by the large grinding disc to rotate around their own axis. It is passive without power. When this vertical roller mill is working, the effect of the grinding roller and the large grinding disc on the material is mainly to grind the material into powder by extrusion. In the existing vertical roller mill, the grinding head is installed on the swing arm that swings around a fixed point. Due to installation and manufacturing errors, the relative positions and gaps between each grinding head and the large grinding disc are differe...

AI Technical Summary

Problems solved by technology

In the existing vertical roller mill, the grinding head is installed on the swing arm that swings around a fixed point. Due to installation and manufacturing errors, the relative positions and gaps between each grinding head and the large grinding disc are different. During the adjustment process, due to the swing of the grinding head The arc, the grinding head, the grinding roller and the large grinding disc often form an included angle, which changes the angle of the material layer at the meshing point, and the change of force affects the quality of grinding and milling and the stability of work.
