Preferably, the fine material outlet at the top end of the pulverizer body is connected with a collecting pipe, and the collecting pipe is provided with a section of soft connection.

Preferably, the lower end of the hopper is provided with a rotary feeder, and an outlet of the rotary feeder is connected with a feeding pipe.

After the structure above the adoption, the utility model discloses a fluid energy mill for lithium iron phosphate production smashes to go to set up first crushing blade and the crushing blade of second in going, and the material is carried this internal through collision each other, the friction, is cuted and is smashed at compressed gas, on diffusing first crushing blade and the crushing blade of second on the rubbing crusher body lateral wall, realizes a lot of repeated crushing, smashes the effect and is promoted by a wide margin, and the product quality who obtains will be superior to prior art's product quality.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, the crusher comprises a crusher body 1, a material separator 2, a material separator 3, a hopper 4, a rotary feeder 5, a conveying gas pipe 6, a material pipe 7, a first crushing blade 8, a second crushing blade 9, a rotating shaft 10, a collecting pipe 11 and a feeding pipe.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1, the utility model relates to a fluid energy mill for lithium iron phosphate production, including rubbing crusher body 1, the top of rubbing crusher body 1 sets up the fine material export, the bottom sets up the coarse fodder export, rubbing crusher body 1 upper portion is the cylinder type, the lower part is the circular cone type, set up disengagement zone and crushing zone from top to bottom in rubbing crusher body 1, the disengagement zone is provided with material separating centrifuge, material separating centrifuge is used for separating fine material and coarse material, fine material gets into the collecting pipe, coarse material gets back to crushing zone again, the symmetrical material import that is provided with on the lateral wall of rubbing crusher body 1 in crushing zone; the crusher comprises a crusher body 1, a hopper 3 and a material pipe 6, wherein the hopper 3 and the material pipe 6 are arranged outside the crusher body 1, the material pipe 6 is transversely arranged, one end of the material pipe 6 is connected with the crusher body 1 through a material inlet, the hopper 3 is arranged above the material pipe 6 and is connected with the material pipe 6 through a discharging pipe 11, the other end of the material pipe 6 is connected with a conveying gas pipe 5, and the discharging pipe 11 is obliquely arranged towards the air inlet direction of the conveying gas pipe 5; be equipped with a plurality of first crushing blades 7 on the lateral wall of the rubbing crusher body 1 in crushing district, the top of material import is provided with pivot 9 that both ends and rubbing crusher body 1 lateral wall rotate to be connected, pivot 9 on be equipped with a plurality of second and smash blade 8.
