Problems solved by technology

Both of the above two feeding methods have the problem of “empty throwing” of the grinding disc, that is, some materials are thrown out of the grinding disc without being ground by the grinding rollers, which reduces the grinding efficiency of the vertical mill and causes energy waste

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0009] Such as figure 1 , 2 As shown, the invention provides a vertical mill feeding device, comprising a feeding pipe 1, a grinding roller 2, and a grinding disc 3; The channel 1-2 and the branch channel outlet 1-3 are evenly distributed to the grinding area 3-1 on the edge of the grinding table 3, and then the material enters each grinding roller 2 for grinding with the rotation of the grinding table 3. The number of runners 1-2 is consistent with the number of grinding rollers 2.

[0010] The embodiments of the present invention are not limited by the above examples, and those of ordinary skill in the art should understand that any other modifications or equivalent replacements that do not deviate from the spirit and principles of the present invention should be equivalent replacements , are all inclu...

Abstract

The invention relates to a feeding device of a vertical mill. The feeding device comprises feeding pipes (1), grinding rollers (2) and a grinding disc (3), wherein the feeding pipes (1) comprise feeding pipe inlets (1-1), runners (1-2) and runner outlets (1-3); the feeding pipe inlets (1-1) are formed in one ends of the runners (1-2); the runner outlets (1-3) are formed in the other ends of the runners (1-2); the runner outlets (1-3) are formed above a grinding zone (3-1) on the edge of the grinding disc (3); feed inlets (2-1) of the grinding rollers (2) are formed in the grinding zone (3-1) on the edge of the grinding disc (3); and the number of the runners (1-2) is the same as the number of the grinding rollers (2). According to the feeding device, through the design, the grinding efficiency of the vertical mill is remarkably improved, and the energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of vertical mills, in particular to a feeding device for vertical mills. Background technique [0002] At present, in the grinding systems of cement plants and steel plants, vertical mills, as a main grinding equipment, are widely used in grinding raw materials, cement, coal powder, slag and steel slag. At present, there are two main feed forms for vertical mills: one is that the material falls to the center of the grinding table through the feeding tube and then is thrown away with the grinding table, and then enters the grinding roller for grinding; the other is that the material directly falls to the grinding table through the feeding tube. After the edge of the grinding disc enters the bottom of a certain grinding roller for grinding, only a small amount of material passes through the rest of the grinding rollers for grinding. Both of the above two feeding methods have the problem of "empty throwing" of...
