Embodiment 1
[0099] The invention provides a crushing chamber structure with different sizes, shapes and structures and different distribution positions, which are combined into a multi-level nested laminated crushing geometric cavity according to certain requirements. On the one hand, materials with different particle sizes can be collected. On the other hand, the crushing load can be homogenized along the height direction of the crushing cavity, thereby improving the crushing efficiency and prolonging the service life of the liner.
[0100] A material crushing chamber structure, comprising:
[0101] The material inlet is used to import the input material having the characteristics of the first material;
[0102]The first crushing cavity structure is connected with the material inlet, the first crushing cavity structure is used to crush the input material, and the first crushing cavity structure has a first crushing structure that matches the characteristics of the first material. A cavi...
Embodiment 2
[0163] Based on embodiment 1, further, there are:
[0164] 1. If figure 1 The design steps of the primary crushing chamber shown are as follows:
[0165] (1) The working surface of the fixed cone liner 1 is made up of several steps, and the concave-convex inner conical surface between each adjacent step, the value of the conical surface length between the number of steps, height and steps and The particle size distribution of the feed is related to the crushing efficiency.
[0166] (2) The working surface of the movable cone liner 2 is made up of several steps, and the concave-convex outer conical surface between each adjacent step. The number of steps on the working surface of the cone liner 1 corresponds to the spacing between the steps.
[0167] (3) The upper area 31, the middle area 32, and the lower area 33 of the primary crushing cavity are formed between the steps on the working surface of the fixed cone liner 1 and the movable cone liner 2, and the bite angle of eac...

Abstract
The embodiment of the invention provides a crushing cavity structure and belongs to the technical field of crushing cavities of cone crushing equipment. The crushing cavity structure comprises a firstcrushing cavity structure body and a second crushing cavity structure body, wherein the first crushing cavity structure body is used for crushing an input material with a first material characteristic, and is provided with a first crushing cavity matched with the first material characteristic and a first lining plate structure; the first crushing cavity and the first lining plate structure form afirst-stage material crushing channel; the second crushing cavity structure body is used for crushing a first-stage material with a second material characteristic, and the first-stage material is obtained after the input material passes through the first-stage material crushing channel; the second crushing cavity structure body is provided with a second crushing cavity matched with the second material characteristic and a second lining plate structure; and the second crushing cavity and the second lining plate structure form a second-stage material crushing channel. The crushing cavity structure is used for the material crushing cavity structure design. The crushing cavity structure has the high effect characteristic and the low abrasion characteristic.
Description
technical field [0001] The invention relates to the technical field of crushing chambers for cone crushing equipment, in particular to a material crushing chamber structure, a multi-stage nested material crushing method and a multi-stage nested material crushing chamber structure design method. Background technique [0002] The working mechanism of the cone crusher is composed of a crushing wall and a socket wall, the crushing wall is eccentrically installed in the middle of the socket wall through the main shaft, and the crushing wall can swing relative to the wall of the socket. During the swinging process of the crushing wall, the materials in the crushing cavity are crushed, so that the particle size of the ore is continuously reduced until the material is crushed to a specific particle size and then discharged out of the crushing cavity. [0003] At present, there are mainly two types of crushers used in my country's crushing industry. One is the traditional spring-type...
