[0001] The utility model relates to the technical field of high-pressure roller mills, in particular to a feeding device of a high-pressure roller mill. Background Art

[0002] As we all know, the roller pressing principle of the high-pressure roller mill is that the material passing through the roller surface completes the "material layer crushing" under the action of two squeezing rollers. Only after the material is squeezed by the roller surface, it has an important effect on the crushing effect of the material. The existing high-pressure roller mill generally has problems such as abnormal vibration of the body and iron feeding. The abnormal vibration of the body may be due to the uneven particle size of the feed material, which is mostly a feeding problem. Therefore, it is necessary to process and screen the material before feeding. For this reason, we propose a feeding device for the high-pressure roller mill. Utility Model Content

[0011] Beneficial Effects

[0012] The utility model provides a feeding device for a high pressure roller mill. It has the following beneficial effects:

[0013] (1) The feeding device of the high-pressure roller mill cooperates with the internal components of the screening assembly. The material passes through the inside of the feeding barrel and falls to the side of the conveying device. The iron products in the material are magnetically attracted by the conveying device crawler. At the same time, the conveying device performs a circular motion. The iron products move with the conveying device to the position of the restraining plate. The restraining plate shovels the iron products off the side of the conveying device and collects them inside the receiving plate. The remaining materials fall to the next layer with the movement of the conveying device, and then pass through another group of conveying devices for one-side screening to remove the metal iron products in the material. In this way, it plays a screening role during feeding and avoids damage to the roller sleeve after iron is fed.

[0014] (2) The feeding device of the high-pressure roller mill cooperates with the internal components of the feeding assembly. The screened materials fall to the side of the crushing plate, and the first telescopic device pulls the connecting block to perform rapid reciprocating motion. The connecting rod rotates inside the ear block, so that the two groups of crushing plates perform relatively rapid extrusion motion. The retraction and resetting of the first telescopic device can adjust the crushing distance between the crushing plates, and the material is initially crushed. This ensures that the particle size of the feed is relatively uniform, thereby improving the efficiency and quality of fine grinding of the high-pressure roller mill.
