Embodiment 1

[0043] The embodiments of the present application disclose a nail-nest mill.

[0044] refer to figure 1 , a nail nest mill, suitable for pulverizing and breaking up powdery materials, including a base 1, a casing 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 casing 2 Tightening assembly 4, the bottom end of the shell 2 is provided with a feeding channel 9 for feeding, the top end of the shell 2 is provided with a discharge channel 10, the inner cavity of the shell 2 forms a pulverizing cavity 11, and the base 1 is also provided with The screening component 5 connected with the discharge channel 10, the material enters the crushing cavity 11 from the feeding channel 9 under the action of negative pressure, and after crushing in the crushing cavity 11, it enters the screening component 5 through the discharge channel 10 for processing. filter.

[0045] refer to figure 2 and image 3...

Embodiment 2

[0065] The difference between this embodiment and the first embodiment is that the feed channel is provided with an air inlet, and the material can inject hot air or additives through the air inlet while entering the pulverizing cavity through the feed 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 injecting additives through the air inlet, the additives are modifiers or surface coating agents to improve the properties of the material.

Abstract

The application relates to a nail nest mill, which belongs to the field of material crushing equipment. A main shaft is arranged inside, a nail plate assembly and a disc assembly are arranged on the main shaft, and one end of the main shaft is produced outside the casing and is connected with a drive assembly; the disc assembly includes at least one disc seat arranged on the main shaft along the axis of the main shaft. The upper part is provided with a plurality of discs in the circumferential direction, and the crushing chamber is provided with a gear cylinder surrounding the disc seat. The nail plate assembly includes a rotor arranged on the main shaft and a stator arranged on the inner wall of the casing. The rotor on the rotor faces the side of the stator. A plurality of groups of crushing columns are arranged along the circumferential direction, and crushing nails are arranged on the side of the stator facing the rotor which are dislocated from the crushing columns. The present application has the advantage of good 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 pulverizes large-sized solid raw materials to the required size. There are four kinds of external forces applied to the solid in the pulverization process: shearing, impacting, rolling and grinding. Shearing is mainly used in coarse crushing and crushing operations, suitable for the crushing or crushing 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 pulverization operation, it is suitable for ultra-fine pulverization of most materials; grinding is mainly used for ultra-fine pulverization or super-large pulverizing equipment, and is suitable for further pulverization after the pulverization operation. [0003] At present, there are many equipments...
