Embodiment 1

[0066] Such as Figure 13 As shown, the present embodiment discloses a grinding process of a horizontal ball mill, comprising:

[0067] The barrel of the ball mill is divided into several sub-compartments, and there are interconnected gaps between adjacent sub-compartments; four sizes of grinding bodies are arranged in each sub-compartment;

[0068] A reinforcement plate is installed in the sub-compartment, the reinforcement plate fits the inner wall of the cylinder, and the reinforcement plate axially pulls the two side walls of the stator compartment tightly;

[0069] Input raw materials into the cylinder, rotate the cylinder for grinding, and obtain materials with d97≤10μm.

[0070] In this embodiment, the cylinder body used has a length of 16 m and an inner diameter of 2.4 m, and the length of each sub-compartment is set to be 0.5 m. The entire cylinder body can be divided into 32 sub-compartments.

[0071] It can be known that when using a horizontal ball mill for mater...

Embodiment 2

[0083] This embodiment discloses a grinding cylinder structure of a horizontal ball mill, the purpose of which is to make the particle size of the material grinded by the ball mill smaller while ensuring sufficient output.

[0084] Such as Figure 1 to Figure 12 Shown is a grinding cylinder structure of a horizontal ball mill, through which the grinding cylinder structure can be used to realize the grinding process disclosed in the technical solution, specifically, the grinding cylinder structure includes a cylinder, and the cylinder is along Several partition structures 2 are arranged at intervals along the direction of the cylinder body, and several reinforcement plates 4 are provided on the inner wall surface of the cylinder body, and two adjacent partition structures 2 are connected and fixed by support members 5; The inner wall surface of the combined cylinder is surrounded by adjacent partition structures 2 to form a sub-compartment 101, and the partition structure 2 is ...

Abstract

The invention relates to the technical field of horizontal ball mills, and mainly discloses a grinding process and a grinding cylinder structure of a horizontal ball mill. The invention sets the cylinder body into a plurality of sub-compartments by arranging a partition structure in the cylinder body, and each sub-compartment Four sizes of grinding bodies are set in the bin to cooperate, which can not only provide a large impact force, but also meet a high impact probability, so that the particle size of the grinding material is greatly reduced, and the grinding efficiency is improved. The difficult problem that the grinding particle size d97≤10μm cannot be achieved; at the same time, the invention sets a reinforcing plate in the cylinder to reinforce the partition structure, so that the partition structure can maintain a normal partition shape, which can improve the strength of the partition structure and effectively ensure the grinding efficiency.

Description

technical field [0001] The invention relates to the technical field of horizontal ball mills, and mainly relates to a grinding process and a grinding cylinder structure of a horizontal ball mill. Background technique [0002] Horizontal ball mill is an ideal equipment for the grinding industry that integrates crushing, grinding, and grading transportation. It can be widely used in cement, electric power, building materials, material industry, non-metallic mines and other industries. And powdery raw materials are ground into powdery materials with required particle size. [0003] At present, there are roughly the following equipment and methods for producing ultrafine powder in my country: [0004] The vertical mill is characterized by large output and the particle size of the ground is 45-150 μm, but it is extremely difficult to further grind. [0005] Raymond mill is characterized by the particle size of the finished product is 10-150μm, but the output is limited. [000...
