The crushing of feed ingredients is a very important part of animal feed mill processing. When producing powdered compound feed, the power consumption of the crushing section accounts for more than 60% of the entire animal feed mill. The animal feed grinding machine has the advantages of small size, high efficiency, convenient operation and maintenance, simple process configuration, and low power consumption. Therefore, hammer type animal feed grinders are commonly used in animal feed processing.
This type of animal feed grinding machine uses high-speed, rotating hammers to break the material. Its simple structure, convenient operation, low price and wide adaptability can crush almost all feed materials except for feed materials with higher water content.
Such as cereals with higher starch content, cakes with higher oil content, husks and straws with higher fiber content. At present, domestic and foreign feed factories generally use this type of animal feed grinding machine.
Crushing refers to the process of changing the physical properties of materials through mechanical force, destroying their internal cohesive force, and turning large bulk materials into small particles that meet the requirements of feed production particle size.
The crushing process is an important part of the animal feed processing in feed mills and farms. The crushing degree is directly related to the subsequent animal feed processing procedures and the quality of feed products.
The hammer-type feed grinder for animals is a kind of impact feed crushing equipment. It has high versatility, small footprint, good crushing quality, quick start without load, flexible transmission connection mode, and weak temperature sensitivity to feed, high productivity and convenient use and maintenance, etc., have been widely used in the feed processing industry at home and abroad.
The raw material falls into the inlet of the animal feed grinding machine by gravity from the top of the crusher, and the falling speed is about 1.64～3.28m/s. The raw material is hit by the hammer for the first time on the top of the rotor.
In the initial crushing zone, due to the raw material The speed at the end of the hammer is very different, and most of the material flow is crushed or broken.
This area is also the only area in the crushing chamber where the material flow is geometrically perpendicular to the animal feed grinding machine screen surface, and the screening capacity of the entire diameter of the screen can be used.
Subsequently, the flow of granular material is accelerated by the hammers to form an annular layer that moves along the inner surface of the animal feed grinding machine screen.
The speed of the annular layer is slightly lower than the speed at the end of the hammer. The speed of the material layer closer to the screen surface is lower, and the speed of the material layer closer to the end of the hammer is higher. This area is narrow and is called the acceleration zone.
The crushed material is to be discharged through the sieve holes, and its speed should reach a discharge speed perpendicular to the screen surface.
The crushed materials close to the screen surface are affected by the friction of the animal feed grinding machine screen surface to reduce its circulation velocity, and are subjected to centrifugal force, pressure and airflow perpendicular to the screen surface to allow it to be discharged out of the animal feed grinding machine screen.
The animal feed grinder base is the installation foundation of the animal feed crusher, and generally adopts a steel plate welded structure to support and connect the rotor of the crusher and other components.
The animal feed grinder base requires good rigidity and firmness, so as to achieve the purpose of reducing vibration, increasing reliability and prolonging service life. The lower part of the animal feed grinder base is the discharge port for crushed materials.
The rotor is the main moving part of the whole animal feed grinder crusher, which is mainly composed of the main shaft, bearing, bearing seat, hammer frame plate, pin shaft, hammer piece and other parts. Because of its high speed during movement, it is necessary before use. It is required that a dynamic balance check must be carried out.
The rotor is the core component of the animal feed grinder pulverizer and one of the rotating transmission components. It forms a pulverizing chamber with the animal feed grinder screen to crush the materials and screen them. Each part of the rotor can vibrate during the animal feed grinder working process.
The animal feed grinder rotor assembly and the motor are connected through a coupling and rotate at a high speed. During the rotation of the animal feed grinder, they collide with the material to break the material.
The animal feed grinder hammer is worn due to high-speed rotation at work, so it is one of the worn workpieces. For this reason, it is required to have a certain degree of hardness, strength and wear resistance.
In addition, the material, structure and arrangement of the animal feed grinder hammer have an impact on the efficiency of material crushing. Therefore, it is generally heat treated before use to increase its strength and wear resistance.
In addition, the arrangement of the hammers also has an impact on the efficiency of the animal feed grinder crusher. There are generally 4 arrangements, namely symmetrical arrangement, spiral arrangement, symmetrical staggered arrangement and staggered arrangement.
The sieve is also one of the easily worn parts in the animal feed grinder pulverizer, which can control the particle size of the pulverized product.
The animal feed grinder screen pieces are fixed on the machine body through the pressing window of the operating door to form a closed crushing chamber. After crushing, the materials will be sieved out of the screen holes to meet the crushing requirements.
The particle size of the material after crushing is controlled by the size of the sieve aperture, that is, the aperture of the sieve must be determined according to the crushing particle size.
The lower part of the operating door is equipped with a roller, which can be moved to the other side after opening it. The animal feed grinding machine screen is compressed by a special pressing mechanism, which is usually opened when the hammer or screen is replaced.
The upper part of the upper casing has a feed inlet, the lower part is connected with the base, and the two sides of the animal feed grinder are equipped with sieve plates respectively, and the base forms a crushing chamber for crushing materials.
Feeding guide mechanism. According to the rotation direction of the animal feed grinder rotor, the material is guided into the crushing chamber from the right or the left.

Keeping your animal feed grinding machine maintenance costs low starts before the animal feed grinding machine is installed at your animal feed plant.
By carefully selecting the animal feed grinding machine's wear parts and determining the best way to operate the feed milling machine in your application, you can minimize required maintenance while ensuring that the animal feed grinder mill provides top grinding performance.
To speed and simplify maintenance, you also should select wear parts designed for easy replacement.
The animal feed grinder should have at least 14 square inches of screen area per horsepower for most applications. Too little screen area will make the animal feed grinder inefficient and cause your material to heat up during grinding.
When using a very fine screen (with holes less than 5⁄64 inch), you may need to use more screen area per horsepower because the screen has less open area.
The number of hammers in your animal feed grinder is called the hammer pattern. For a large-diameter animal feed grinder (with a diameter of 38 inches or more) that uses hammers more than 10 inches long, the number of hammers you'll need for a screen with large (at least ⅛-inch) holes is typically one hammer per every 2.5 to 3.5 horsepower.
For a large-diameter animal feed grinder with the same hammer size but smaller screen holes, you may need more
hammers to prevent them from "rocking" back and forth on their pins and quickly wearing and enlarging
the hammer holes. To produce a finer grind, you should also use more hammers.
In most applications, the clearance between the hammer tip and screen has only minor influence on grinding performance. Generally, a larger tip-to-screen clearance provides the greatest grinding capacity and efficiency.
For a fribrous or other tough-to-grind material, however, setting the hammer tip near the animal feed grinder
screen can achieve a finer grind, but this can also increase screen and hammer wear.
To achieve a finer final size when using a feed grinder screen with holes smaller than ⅛ inch, you should use a high tip speed (greater than 18,000 fpm).
This speed is more efficient in producing finer grinds and permits the hammer to do more of the grinding work, minimizing screen wear. Use a lower tip speed and a screen with larger holes to produce a coarser, more uniform grind.
In livestock and poultry breeding, proper crushing and processing of feed is not only convenient for mixing ratio, but also can improve the palatability of feed, which is favored by livestock and poultry. At the same time, it is conducive to the digestion and absorption of livestock and poultry, and improves the effective utilization rate of feed.
However, due to the different types of livestock and poultry, the granularity of feed crushing and processing is
also different. According to the survey of relevant data, various feeds for piglets have a feed particle size of
0.85～0.95mm in diameter compared with a diameter of 1.7～1.8mm.
The percentage increase in digestibility is: organic matter 3～4%, crude protein 4～5%, crude fat 10～14%, crude fiber 5～6%, nitrogen-free extract 2～3%. It is not difficult to see from this that an appropriate feed particle size is one of the necessary ways to improve feed quality and increase feed remuneration.
The particle size of feed products after crushed feed materials should be determined according to the species of
raw materials and different types of livestock and poultry. Several different types of livestock and poultry have
different requirements for feed particle size:
