Grinding is accomplished by many types of manual and mechanical operations involving impact, attrition and cutting. a) Hammer mills: are mostly impact grinders with swinging or stationary steel bars forcing ingredients against a circular screen or solid serrated section designated as a striking plate. The material is held in the grinding chamber until it's reduced to the size of the openings in th ...

Among the various stages of the pelleting process, grinding is one of those that consume more energy, but it’s essential for pelletizing because it allows to create a homogeneous mixing and to reduce the volumes. In fact, in the compound-feed production process 60% of the total energy consumption is used for pelleting, 16% for milling, 14% for conveying, 7% for receiving, 2% for mixing and 1 ...

The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. In fact, only then the assortment of ingredients (formula) will create the best results and uniformity of the feed pellets is secured. Prior to the mixing process, the feed ingredients have been weighed and ground and the vitamins and minerals have been added to the feed compou ...

Mixing may be either a batch or a continuous process. Batch process means discontinuous, the simplified production sequence as follows: venting spigot must always be open to vent air in a filter, preferably slightly under pressure; filling through the product inlet, with the unloading door closed: mixing, with unloading door closed, product inlet closed or open only if connected with a closed feed ...

The result of mixing dry solid ingredients may be a definite pattern of particle segregation. This is due to differences in the physical properties of ingredients and the shape and surface characteristics of the mixer. Particle size may be the most important factor in causing this phenomenon. In general, the smaller and the more uniformly sized the ingredients are prepared, the more nearly they w ...

An optimal grinding requires the right amount of intake of air, which is cleaned in the nozzle filters. This also guarantees an economic use of the hammer mill. The air is necessary to quickly transport the fine product from the area of the hammers through the grinding sieve and, at the same time, to cool the product. By the ventilator, mounted in front of the filter a vacuum is generated and air ...

To produce pellets or extruded feeds of acceptable quality the particle size of the ground materials must be correct. Finer grinding will result in a better-quality pellet or extruded feed, increases the capacity of the pellet mill or extruder, and reduces wear of the pellet mill or extruder working parts such as dies, rollers, and worms. Because animal needs vary considerably, the degree of proc ...

Sandeep kumar , our technicians say that a reduction in the air flow rate leads to:• a reduction in mill capacity• finer product• higher specific energy consumption• greater heating during milling• greater wear• greater dust formation.With screen holes diameter lower than 3 mm is not possible to work without aspiration because the risk of clogging is too high.

Thank you all for your interest in this topic. I am pleased to see that there are many professionals in the Animal Feed industry who are happy to share their experiences and knowledge with others.Based on the experience of La Meccanica, I agree with Mr. Enrique Diaz when he says that the question is not whether pre-milling is better than post-milling or vice versa. The question is where and when t ...
