Embodiment 1

[0043] The embodiment of the application discloses a nail nest mill.

[0044] refer to figure 1 , a nail nest mill, suitable for crushing and breaking up powdery materials, including a base 1, a housing 2 is fixed on the upper surface of the base 1, and a drive assembly 3 and a tensioner are arranged on the side of the base 1 away from the housing 2 Tight assembly 4, the bottom end of the housing 2 is provided with a feed channel 9 for feeding, the top of the housing 2 is provided with a discharge channel 10, the inner cavity of the housing 2 forms a crushing chamber 11, and the base 1 is also provided with a The screening assembly 5 connected with the discharge passage 10, the material enters the crushing chamber 11 from the feed passage 9 under the action of negative pressure, and after being crushed in the crushing chamber 11, it enters the screening assembly 5 through the discharge passage 10 for further processing. filter.

[0045] refer to figure 2 with image 3 , t...

Embodiment 2

[0065] The difference between this embodiment and the first embodiment is that: an air inlet is provided on the feeding channel, and hot air or additives can be injected through the air inlet while the material enters the crushing chamber through the feeding channel. When the hot air is injected through the air inlet, the temperature of the hot air reaches 400°C, which can dry the powder and make the powder easier to disperse. When the additive is injected through the air inlet, the additive is a modifier or a surface coating agent to improve the performance of the material.

Abstract

The invention relates to a nail nest mill, and belongs to the field of material crushing equipment. The nail nest mill comprises a shell, a feeding channel is arranged at the bottom end of the shell, a discharging channel is arranged at the top end of the shell, a crushing cavity is formed in an inner cavity of the shell, a main shaft is arranged in the crushing cavity, a nail disc assembly and a disc assembly are arranged on the main shaft, and one end of the main shaft extends out of the shell and is connected with a driving assembly. The disc assembly comprises at least one disc seat arranged on the main shaft in the axis direction of the main shaft, a plurality of discs are arranged on the disc seat in the circumferential direction, and the crushing cavity is provided with a tooth cylinder surrounding the disc seat. The nail disc assembly comprises a rotor arranged on the main shaft and a stator arranged on the inner wall of the shell, a plurality of groups of crushing columns are arranged on the side, facing the stator, of the rotor in the circumferential direction, and crushing nails staggered with the crushing columns are arranged on one side, facing the rotor, of the stator. The nail nest mill has the advantage of being good in material crushing effect.

Description

technical field [0001] The present application relates to the field of material crushing equipment, in particular to a nail nest mill. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. There are four types of external forces applied to solids during the crushing process: shearing, impact, rolling, and grinding. Shearing is mainly used in coarse crushing and crushing operations, and is suitable for crushing or crushing operations of tough or fibrous materials and bulk materials; impact is mainly used in crushing operations, suitable for crushing brittle materials; rolling is mainly used in In the high-fineness crushing operation, it is suitable for ultrafine crushing operations for most materials; grinding is mainly used for ultrafine crushing or ultra-large crushing equipment, and is suitable for further crushing operations after crushing operations. [0003] At present, there are many equipments for c...
