Two-layer dual-drive vertical ring mill

Abstract

The invention discloses a two-layer dual-drive vertical ring mill which comprises a machine frame, wherein a barrel is mounted on the machine frame; a material hopper is mounted at the top of the barrel; a material guide disc is mounted below the material hopper; a lower drive shaft erecting frame is mounted in the machine frame; a lower drive shaft is mounted in the lower drive shaft erecting frame; an upper drive shaft erecting frame is mounted at the upper part of the barrel; an upper drive shaft is mounted in the upper drive shaft erecting frame; and ring milling devices are mounted on the lower drive shaft and the upper drive shaft. The two-layer dual-drive vertical ring mill disclosed by the invention has the following technical effects: 1, the velocities of the ring milling devices at the upper and lower layers can be adjusted; and 2, the rotating directions of the ring milling devices at the upper and lower layers can be opposite to each other, so that a material is prevented from rotating in a dropping process, accelerated passing of the material is avoided, and the grinding efficiency is improved.

Description

technical field [0001] The invention relates to a vertical ring mill. Background technique [0002] The vertical ring mill is a kind of high-efficiency and energy-saving powder grinding machine. The central shaft is equipped with a multi-layer ring grinding device. Through the rotation of the central shaft, the hammer wheel on the ring grinding device is driven to both revolution and self-rotation. The hammer wheel relies on inertia Centrifugal force crushes the materials falling from the ring wall. Since the ring grinding devices of each layer are installed on a central shaft, the speed of the ring grinding devices of each layer is the same and cannot be adjusted. Because the rotation direction of the multi-layer ring grinding devices Consistent, the material accelerates to pass downwards, resulting in low grinding efficiency. Contents of the invention [0003] The object of the present invention is to provide a double-layer double-drive vertical ring mill. [0004] The...
