Embodiment 1

[0033] The invention provides a bionic crushing device with adjustable particle size for tidal ore, which is a bionic-based device capable of crushing viscous solid minerals into solid powders with different particle sizes. Such as figure 1 As shown, the crushing device includes a first crushing roller 100 , a second crushing roller 200 and a particle size adjustment mechanism 300 .

[0034] The first crushing roller 100 is arranged with a first crushing groove 100a and a first crushing grain 100b along its axial direction. And the first crushing groove 100a and the first crushing grain 100b are spaced apart sequentially, such as figure 2 shown. In the same manner, the second crushing roller 200 is arranged with a second crushing groove 200a and a second crushing grain 200b along its axial direction. Moreover, the second crushing groove 200a and the second crushing grain 200b are sequentially spaced apart. During installation, such as figure 2 As shown, the first crushi...

Embodiment 2

[0044] This embodiment may be a further improvement and / or supplement to Embodiment 1, and repeated content will not be repeated here. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment.

[0045] In this embodiment, the particle size adjustment mechanism 300 acts on the second support mechanism matched with the second transmission shaft of the second crushing roller 200 in the same manner as the first support mechanism acting on the first transmission shaft of the first crushing roller 100 on, used to adjust the radial position of the second crushing mixer 200.

[0046] Preferably, both the first crushing roll 100 and the second crushing roll 200 are configured with a particle size adjusting structure 300 . However, in terms of equipment cost, it is a better choice that the particle size adjusting mechanism 300 only acts on the supporting mechanism ...

Abstract

The invention relates to a bionic crushing device with adjustable particle sizes of humid ore. The bionic crushing device can selectively obtain humid ore powder particles with different particle sizes. The bionic crushing device comprises two rollers rotating in the opposite directions and an adjusting mechanism for adjusting the spacing between the rollers. A plurality of annular protrusions which are continuously spaced from one another through annular grooves are arranged on the peripheral surfaces of the two rollers in the axial direction, wherein annular protrusions of one crushing tooland annular grooves of the other crushing tool form a crushing opening capable of wriggling in a way of circular coordination during the opposite rotation of the two rollers, and the diameter of the crushing opening can be changed based on the adjusting mechanism, so that the humid ore powder particles with the different particle sizes are selectively obtained. Moreover, in the process of wriggling, the crushing opening can not only crush the humid ore, but also improve the lubrication performance of the contact interface between the humid ore and the crushing tools, so as to effectively prevent the humid ore powder particles from being attached / stacked on the crushing tools due to the viscosity of the humid ore powder particles.

Description

technical field [0001] The invention relates to the technical field of viscous ore crushing, in particular to a bionic crushing device with adjustable particle size for tidal ore. Background technique [0002] A crusher is a mechanical device that crushes large-grained materials into small-grained powders by at least one or several combinations of extrusion, tearing, impact, and shearing. Particle size is the most critical parameter of crusher crushing parameters, which is related to energy efficiency, cost and crushing quality. Therefore, how to meet the particle size required by the downstream production line is an urgent technical problem in the research and development of the crusher. [0003] For example, the Chinese patent publication No. CN102824936A discloses a meshing extrusion crusher that can automatically adjust the gap between the pressing rollers. The crusher includes a fixed pressure roller driven by a power system, and a movable pressure roller meshed with ...
