With the acceleration of industrialization and urbanization, the urban
population continues to increase, and the living standards of urban and rural
residents continue to improve. The demand for livestock products will continue
to increase, especially the increase in farmers’ incomes, and the consumption of
livestock products will increase substantially. Coupled with the increased
demand for high-quality livestock products in the new round of consumption
upgrades, my country's feed industry showed a pattern of sustained and stable
development in 2015, and the total annual feed output is expected to exceed 250
million tons. Under such a background, the research and application of feed
equipment and production process have been developed rapidly. This article will
start from a typical feed production process and explain the equipment selection
for each section of feed production in the actual production process. Use
maintenance and other related issues.

-The process flow of a small and medium-sized livestock and poultry feed
factory is composed of raw material receiving, crushing, batching, mixing,
granulating, cooling and screening, and finished product packaging sections; the
core production equipment is grinder, mixer, granulator, etc. , The selection of
these equipments play a vital role in feed production and ensuring the quality
of feed. The following will briefly discuss the role and selection of the three
types of equipment in production.
The role and selection of crusher
Crushing is an operation method that uses mechanical methods to overcome the
cohesion of solid materials and break them. It is one of the most important
processes in the feed processing process. It is an important factor affecting
feed quality, output, power consumption and processing costs. . The effects of
crushed feed: a. Increase the surface area and particle size of the feed, which
is beneficial to the digestion and absorption of animals. Animal nutrition
experiments have shown that reducing the particle size improves the digestion
and absorption of dry matter, protein and energy, and reduces the feed-to-meat
ratio; b Improve and enhance the processing performance of materials. Through
pulverization, the particle size of the material can be basically the same, and
the material classification after mixing is reduced; for micro-elements and some
small component materials, only pulverized to a certain degree to ensure that
there are enough particles to meet the requirements of mixing uniformity;
Another example is the granulation process, the particle size of the crushed
material must consider the interaction between the crushed particle size and the
pelleted feed. The crushed particle size will affect the durability of the
pellets and the stability of the aquatic feed in the water; c The size of the
crushed feed can be significantly increased The conversion rate of feed can
reduce the excretion of animal feces, improve the utilization rate of animal
feed, and improve the efficiency and quality of subsequent feed mixing,
conditioning, pelleting, and expansion.
