The embodiment of the application provides a grind machine with static screen cloth, has solved current grinding medium and has easily caused sound ring damage, hourglass ball problem when less.

In order to achieve the above object in the prior art, the utility model adopts the following technical scheme:

a grinder with static screen includes a feed inlet, a discharge outlet and a grinding chamber, in which a grinding rotor, a grinding pin and a discharge rotor are arranged, the grinding pin grinds materials by stirring grinding media, and further includes: the front shroud, it is located one side tip in grinding the chamber, the front shroud includes: the discharging channel is formed on the front cover plate and extends into the protruding part in the grinding cavity; and the static screen is arranged in the discharging rotor, and one end of the static screen is fixedly connected with the protruding part.

Further, the discharge channel is communicated with the inside of the static screen.

Further, the front cover plate is arranged at one side end of the grinding cavity, the discharge port is formed in the front cover plate, the front cover plate further comprises a protruding portion extending into the grinding cavity, the protruding portion is fixedly connected with one end of the static screen, and the discharge channel is communicated with the inside of the static screen.

Further, the other end of the screen is provided with an end cover.

Furthermore, the discharging rotor is driven by a rotating shaft, and a machine seal is arranged on the position, close to the feeding hole, of the rotating shaft.

Furthermore, a bearing seat is arranged on one side of the machine seal, and a bearing is arranged inside the bearing seat.

Further, a plurality of grinding rod pins are arranged on the grinding rotor along the circumferential direction.

Compared with the prior art, the beneficial effects of the utility model are that:

1. by arranging the static screen, a bead material separation system of the dynamic and static rings is omitted, so that a small grinding medium can be used, and the grinding medium can be effectively and completely separated from the material when the grinding medium is small, thereby improving the grinding effect;

2. through setting up static screen cloth on the apron before, can realize static screen cloth and discharging channel's direct intercommunication, simplify ejection of compact structure, make things convenient for the change and the washing of screen cloth.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, a grind machine, it includes feed inlet 1, discharge gate 6 and grinds the chamber 8, grind the intracavity and be equipped with grinding rotor 2 and ejection of compact rotor 4, grind rotor 2 and be equipped with a plurality of grinding rod round pins 3 along the circumferencial direction. After the grinding material enters the grinding cavity 8 from the feeding hole 1, the grinding material is ground by the grinding medium, and the ground material and the grinding medium are discharged from the discharging hole 8 after being centrifugally separated by the discharging rotor 4.

As shown in fig. 1, the grinding machine of the present invention further includes a front cover plate 9, which is disposed at a side end of the grinding chamber 9, the front cover plate 9 includes a discharging channel 91 and a protrusion 92, the discharging channel 91 is formed on the front cover plate, and the protrusion 9 extends into the grinding chamber 8.
