Embodiment Construction

[0035] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps. Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0036] Such as figure 2 The ball mill shown includes a ball mill cylinder 8 and a collection chamber 9, the ball mill cylinder is divided into a front chamber and a rear chamber by a compartment grate plate 19; one end of the collection chamber communicates with the ball mill cylinder through the outlet grate plate 4; the upper part of the other end of the collection chamber passes through The air duct 5 is connected with the blower fan, and the bott...

Abstract

The invention discloses a ball mill which comprises a ball milling barrel and a collecting bin, wherein the ball milling barrel is communicated to one end of the collecting bin through a bin outlet grate plate; a fan is connected to the upper part of the other end of the collecting bin through an air pipe, and a material storage is communicated to the lower part of the other end of the collecting bin through a material pipe; an air guide pipe is also arranged in the collecting bin, one end of the air guide pipe extends into the ball milling barrel, the other end of the air guide pipe extends into the air pipe, and an air baffle is arranged between the air guide pipe and the air pipe or the collecting bin; an air guide hole is formed in a collecting bin housing. Due to the adoption of the ball mill, the flow quantity and speed of airflow in a grinder can be increased according to the production needs, sufficient grinding time of materials in the grinder is guaranteed, and the quality and yield of finished products can still be ensured when the comprehensive moisture content of the grinding materials is relatively high.

Description

technical field [0001] The invention relates to a ball mill for material grinding, such as a cement grinding machine. Background technique [0002] When the ball mill grinds materials, a large amount of heat energy will be generated due to friction, which will increase the internal temperature, and the materials to be ground, such as cement, contain more or less water (generally 1%-6%), and the water in the materials will be in the process of grinding. As the temperature rises it becomes water vapor. If the water vapor cannot be discharged in time, in the high-temperature and high-humidity environment, paste milling will easily occur in the ball mill (in a high-temperature and high-humidity environment, under the combined action of water and static electricity, fine particle materials will be adsorbed on the inner wall of the ball mill, compartments, outlets, etc. The surface of the grate plate and the surface of the grinding body are called paste mill). Without changing t...
