Problems solved by technology

If the attapulgite is crushed after water evaporation, the cohesive force between the attapulgite will be destroyed due to the evaporation of water, which will directly affect the physical properties of the attapulgite ore, and indirectly affect the performance of the lithium battery nanomaterial separator. Decreased significantly
Moreover, with the improvement of environmental protection requirements and energy-saving requirements, the process of drying and crushing attapulgite can no longer meet the relevant requirements.
In addition, drying and crushing of attapulgite is a discontinuous process, which will affect the crushing efficiency of attapulgite particles

Embodiment 1

[0041] Such as image 3 Shown is a conventional conventional crushing roll. It comprises several crushing teeth spaced apart from each other in the circumferential direction. The teeth are discontinuous, and the shape of the teeth changes suddenly. During use, a lot of viscous materials will accumulate at the roots of a large number of crushing teeth, which will cause the crushing port to be blocked after accumulation to a certain extent. Bionics is a principle based on the structure and function of organisms, and will be applied to invent new equipment, tools and technologies based on these principles, creating an advanced technology suitable for production and promoting scientific development. After long-term research and exploration on how earthworms, dung beetles and pangolins move in soil, the inventors of the present invention found that the non-smooth body surfaces of earthworms, dung beetles and pangolins have the effect of reducing adhesion and desorption. Through t...

Embodiment 2

[0051] On the basis of Example 1, this implementation discloses a viscous-reducing and desorbing crushing tool for attapulgite. 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.

[0052] This embodiment discloses a crushing cutter capable of directly crushing massive cohesive attapulgite ore into cohesive attapulgite ore.

[0053] Such as figure 1 As shown, the crushing tool includes a first crushing roller 100 and a second crushing roller 200 . The first crushing roller 100 and the second crushing roller 200 are arranged in parallel with each other. In addition, both are provided with a rotating shaft and a rotating drive mechanism, respectively. The respective rotary driving mechanisms drive the rotating shafts to drive the first crushing roller 100 and the second crushing roller 200 to rotate relative to each other or the two to rotate relati...

Embodiment 3

[0062] On the basis of Example 1 or 2, this implementation discloses a viscous reduction, desorption and crushing method for attapulgite. 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.

[0063] It can crush the cohesive attapulgite ore into cohesive attapulgite particles and at the same time prevent the cohesive attapulgite particles from adhering to the crushing tool.

[0064] The crushing method includes:

[0065] The first crushing roller 100 and the second crushing roller 200 that can rotate opposite to each other can form a crushing opening 300 during the rotation of at least one of them, and the crushing opening 300 is used to crush the cohesive attapulgite ore into cohesive attapulgite particles;

[0066] Along the axial direction of the first crushing roller 100, first annular crushing grains 100a in a wave state are arranged at interva...

Abstract

The invention relates to a debonding and desorption crushing cutter for a damp ore. The cutter comprises a crushing roller, wherein the crushing roller is provided with crushing teeth which are arranged at intervals in the circumferential direction of the crushing roller and are used for crushing the damp ore into damp ore particles, the tooth bottoms of the crushing teeth are in transitional connection with the tooth tops of the crushing teeth in a non-abrupt manner via embedded ramp surfaces, so that the crushing teeth can form non-abrupt crushing ports with matched crushing grooves, in thedirection of rotation of the crushing roller, the adjacent approximately platform-shaped tooth tops behind the embedded slope surfaces of the crushing teeth extend and transition to disengagement slope surfaces in a non-abrupt manner, and the disengagement slope surfaces transition and extend in the direction of rotation of the crushing roller to the root portions of the adjacent embedded slope surfaces of the crushing teeth in a non-abrupt manner so as to form at least double curvature transitional connection parts between every two adjacent crushing teeth. According to the cutter, working environment in current attapulgite clay crushing can be effectively improved, and the anti-sticking property of the attapulgite clay can be conveniently and effectively improved.

Description

technical field [0001] The invention relates to the technical field of crushing cutters, in particular to a crushing cutter for viscous reduction and desorption for tidal ore. Background technique [0002] Attapulgite Clay is a rare non-metallic mineral resource, which has a wide range of medical applications in many fields such as agriculture and animal husbandry, building materials, petroleum, metallurgy, and food. "Attapulgite clay" is a layer chain structure of water-rich magnesium aluminum silicate ore minerals. At present, about 70% of the proven attapulgite reserves in the world are in China. Attapulgite needs to be crushed before further processing, and its particles are required to be mostly concentrated between 5mm and 20mm. But unlike other broken raw materials, attapulgite is rich in water (water content as high as 20% to 45%). When it is rich in water, the cohesion of attapulgite can reach about 70KPa, and the internal friction angle can reach 40°, so it show...
