Cyclic breaking and screening device for feed

Abstract

The invention discloses a cyclic breaking and screening device for a feed. The device comprises a screening box, the top plate of the screening box is communicated with the discharging end of a crusher, the sidewall of the screening box is provided with a first sieve plate, a magnetic rod group and a second sieve plat, one side of the first sieve plate is in sleeve connection with one end of a return tube, the other end of the return tube is in sleeve connection with a feeding tube, a spiral track is mounted in the feeding tube, the feeding tube is communicated to the feeding end of the crusher, one side of the second sieve plate is in sleeve connection with a discharging tube, and the bottom plate of the screening box is provided with a collection port. The feed is broken by the crusher and then enters the screening box, the unsatisfied large-granule feed slides into the return tube along the first sieve plate, enters the feeding tube through the return tube, is conveyed into the crusher through the spiral track, and is broken again, the feed goes through the first sieve plate and falls on the magnetic rod group, iron scraps in the feed are sucked out and then fall on the second sieve plate, the satisfied feed slides into the discharging tube along the second sieve plate and is bagged, and the unsatisfied powdery feed falls down from the second sieve plate, and flows out of the collection port.

Description

technical field [0001] The invention relates to the technical field of feed production equipment, in particular to a feed circulation crushing and screening device. Background technique [0002] Feed is the general term for the food of animals raised by everyone, including more than ten varieties of feed materials such as soybeans, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, and feed additives. In the production process, the raw materials need to be mixed, tempered and processed into lumps, then the lump feed is broken into pellet feed, and finally the crushed pellet feed is screened, and the feed that meets the specifications is packaged. The feed needs to be processed. The current screening equipment only selects the larger feed particles, but the feed particles that are too small are not screened, resulting in powdered feed particles mixed in the finished product packaging. At the same time, the feed is crus...

[0002] Feed is the general term for the food of animals raised by everyone, including more than ten varieties of feed materials such as soybeans, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, and feed additives. In the production process, the raw materials need to be mixed, tempered and processed into lumps, then the lump feed is broken into pellet feed, and finally the crushed pellet feed is screened, and the feed that meets the specifications is packaged. The feed needs to be processed. The current screening equipment only selects the larger feed particles, but the feed particles that are too small are not screened, resulting in powdered feed particles mixed in the finished product packaging. At the same time, the feed is crushed It is easy to be mixed with iron filings, and the iron filings cannot be screened out, resulting in a decrease in the yield of feed products. Therefore, we propose a feed recycling crushing and screening device to solve the above problems
