Using method for feed pulverizer with separating screen

Abstract

The invention discloses a using method for a feed pulverizer with a separating screen. The using method comprises the following steps that A, during working, raw materials such as corns and bones are extruded and pulverized when entering a gap between coarse crushing rollers through a material inlet and then are extruded and pulverized again through the gap between the coarse crushing rollers; B, the coarse crushing rollers are adjusted: a control device controls a piston rod of an upper adjustment cylinder to extend to push one of the coarse crushing rollers to slide on a sliding rail so as to adjust the gap between the two coarse crushing rollers; C, fine crushing rollers are adjusted: the control device controls a piston rod of a lower adjustment cylinder to extend to push one of the fine crushing rollers to slide on the sliding rail so as to adjust a gap between the two fine crushing rollers; D, the separating screen vibrates to screen materials falling down from a material outlet of a stander, and fine materials are led out along a fine material outlet so as to be collected; a coarse material outlet in the side surface of the separating screen is used for introducing large-particle materials into the material inlet through a conveying belt for secondary pulverization. The using method disclosed by the invention is simple; a used product is simple in structure and convenient to use; the materials can be screened after being pulverized, so that secondary screening can be reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of poultry breeding, in particular to a method for using a feed grinder with a sorting screen. [0003] Background technique: [0004] At present, large-scale chicken farms have adopted automatic chicken raising equipment, and feed crushing equipment is one of them. Poultry feed is an important part of my country's current feed products. my country is the country with the largest poultry feed production. The annual poultry feed total The volume is 50 million tons. The feed consists of hard pellet feed and powdered aquatic feed, of which the total output of hard pellet poultry feed accounts for more than 90%. And these hard pellet feeds generally all need to use pulverizer to pulverize. Raw materials such as corn and bones need to be crushed by a feed mill before being processed into feed. The structure of the existing feed mill generally includes: a frame, a feed port arranged at the upper end o...

AI Technical Summary

Problems solved by technology

The existing feed grinder has poor crushing effect and low degree of automation, which cannot meet the crushing needs. Moreover, after crushing, it is directly poured out along the discharge port, and cannot be sieved.
