fish food grinder
The fish food grinder is mainly suitable for the grinding system of various fish feed, shrimp feed and other aquatic feed, pet feed, piglet feed, etc. It is widely used in fish feed factory, shrimp feed factory, aquatic feed factory, livestock and poultry feed factory.
Generally, when producing ordinary fish feed, the particle size of the raw materials is required to be 40-60 mesh, but when producing special aquatic pellet feed (shrimp feed, eel feed, etc.), the particle size of the raw material must be more than 80 mesh.
Therefore, when a fish feed company chooses fish feed milling machine, it is necessary to consider many factors such as production varieties, crushing fineness requirements, quality, price, work efficiency and production cost of crushing equipment.
Type of fish food grinder
Fish feed grinder is an important equipment in feed production, especially the development of aquatic feed has higher requirements for crushing equipment. The design of RICHI fish feed milling machine is mainly considered comprehensively from the aspects of saving power consumption for pulverization, increasing the output of the fish feed grinding machine, controlling the uniformity of the pulverizing particle size, and reducing the loss in the pulverizing process.
Hammer strengthening research should be comprehensively considered from the aspects of wear resistance, impact resistance, long life and low cost. The screen should pay attention to strength and stiffness, reasonable opening rate and punching technology.
Water drop fish food grinder
The water drop fish food grinder is an advanced model. This machine fully exploits the advantages of the horizontal fish feed pulverizer. Using unique design ideas, one fish feed milling machine can form two kinds of hammer-screen gaps, which are suitable for ordinary pulverization and fine pulverization respectively. The pulverization fineness is more uniform, the finely pulverized particle size meets the production requirements of ordinary fish feed, and the power consumption is lower, which can reduce the production cost. After the model entered the market, it was favored by feed manufacturers.
The water drop type fish feed milling machine not only crushes twice, but can also change the position of the hammer at any time to adjust the coarse, fine and fine crushing of the material. The average diameter of the crushed particles is 100Lm-500Lm. Drop-type fish food grinder is a good choice for pulverizing aquatic feed.

If special aquatic feeds such as shrimp feed, eel feed, turtle feed, and crab feed are produced, the crushing particle size is required to be finer, and the general crusher cannot meet the requirements of micro crushing, and a fine powder grinding machine must be used for processing.
The micro-grinding of aquatic feed often adopts the secondary grinding process, that is, the first coarse grinding and then the fine grinding. Among them, the second micro-grinding generally uses a micro-grinder and a micro-classifier to achieve the required grinding particle size.
Ultra fine powder grinder
The vertical shaft ultra fine powder grinder is a micro-grinding equipment that integrates grinding, screening and separation, and can meet the grinding particle size requirements of special aquatic feeds.
Since the crushing chamber and the grading chamber are located in the same body, the ultra fine powder grinder can simultaneously complete the processes of crushing, air screening, separation and re-crushing, which can effectively prevent over crushing. Built-in high-precision micron-level wind classification, the crushing particle size can reach 60-200 mesh, and can be adjusted arbitrarily as needed.
The temperature rise of the crushed material is low, especially suitable for heat-sensitive materials. The whole process has compact structure, small footprint, low power consumption per ton of material, uniform particle size and high output after crushing. It is an ideal micro-grinding equipment for producing special aquatic feed.

Crushing is a necessary section in the processing of all feed products. It is necessary for animals to eat and digest feed, and it is also a prerequisite for subsequent batching, mixing and pelletizing. The purpose of fish feed grinding machine is to increase the surface area of the feed, make the digestive enzymes in the gastrointestinal tract fully contact with the feed, improve the digestibility of the feed by the animals, and increase the feed remuneration.

How to choose fish food grinder?
Different types of fish feed grinding machines and changes in the structure of the fish feed grinder have a considerable impact on the pulverized materials.
Generally, ultrafine grinders are suitable for pulverizing feeds with high protein, high fat and low cellulose content. On the contrary, hammer mills are suitable for pulverizing feeds with high fiber, low protein and low fat.
For different fish food grindering machine, air assist is very important. Pneumatic transport of pulverized material serves two important purposes. It transports the pulverized product from the electric fish mill machine to the receiving device, and the material in the pulverizing chamber is cooled by the surrounding air.
At present, fish feed manufacturers mainly focus on the following aspects when choosing a fish food grinder:
①How to make the crushed material reach the required particle size and reduce the energy loss in the crushing process. At present, many fish mill manufacturers take measures such as increasing the screening area, destroying the circulation layer of the crushing chamber, increasing the opening of the sunburn, and strengthening the air suction after crushing to improve the crushing efficiency.
②The durability of the vulnerable parts of the fish feed grinding machine is also an important factor to be considered when choosing a fish grinder. High-quality hammers can reduce the consumption of hammers in the crushing process and increase the output of the crusher per unit time.
③The optimization of the processing accuracy and assembly accuracy of the fish food grinder is also an important consideration in the selection of the fine grinding machine.
In order to produce high-quality aquatic feed that meets the requirements of aquatic organisms’ survival and growth, the design of water feed crushing program is the top priority. Richi Machinery will decide what fish food grinder machine to use and what crushing technology process to use by analyzing the species of aquatic animals, analyzing the characteristics of raw materials, analyzing the types of raw materials, and analyzing the requirements for the quality of aquatic feeds.
Requirements for the crushing fineness
As we all know, the feed of aquatic animals must be finely crushed to meet the needs of animal digestion and pelleting. The appropriate grinding fineness is affected by factors such as animal growth stage, nutritional needs, feed processing technology and fish food grinder. Reasonable crushing fineness selection is also an inevitable requirement to reduce costs, increase production capacity and ensure product quality.
Requirements of aquatic animal nutrition on grinding fineness
From a nutritional point of view, the smaller the crushed particles of the material, the more surface area there is to contact the digestive enzymes, so as to achieve a higher utilization rate of digestion. Generally speaking, the digestive tract of aquatic animals is short. In order to speed up digestion and absorption, the crushed aquatic feed particle size by fish food grinder should be smaller than that of livestock and poultry feed.
For example, in the production of eel feed, the particle size should reach 80-120 mesh. In addition, the aquatic animal compound feed has high protein content and low carbohydrate content, and the feed particle structure is compact, requiring high cohesion and water resistance. The nutritional requirements of these aquatic animals all require reasonable crushing of feed.
Requirements for grinding fineness in production
Appropriate grinding fineness plays an important role in processing. The smaller the pulverization fineness of the material, the easier it is to absorb the steam in the conditioner, so that the gelatinization is more sufficient. In addition, the extrusion force required for the granulation or expansion of finer materials is relatively small. If the pulverization fineness is too large, the energy consumption when passing through the fish feed pellet machine ring die or pressing roller will relatively increase, and the quality of pelleting and puffing will be affected, resulting in easy breakage of feed pellets and poor water stability.
There is a similar situation in extrusion granulation. When the material particles are large, it often takes more energy to crush the large particles. In addition, some fish feed pellet making machines cannot use large material particles due to the problem of extrusion structure, which may easily cause blockage of the ring die, thereby affecting the output and product quality. In addition to the grinding fineness of fish food grinder, the distribution range of the material particle size also has a very important influence on the processing.
Generally speaking, the smaller the distribution range of material particle size, the better. For example, during puffing, too large a difference in pulverized particle size can result in a lower level of starch gelatinization in the modulator, as more energy is expended in this case to gelatinize larger material particles. For the production process of first pulverizing by fish food grinder and then batching, since the raw materials are separately pulverized in the previous stage of processing, it is difficult to limit the particle size to a relatively narrow range in the subsequent mixing section.
Therefore, the general aquatic feed production process adopts the processing technology of first batching and then crushing or secondary crushing, which can make the particle size range of the material relatively uniform. In addition, reasonable screening of materials after secondary crushing is also an effective measure to improve the uniformity of crushing.
The mixing uniformity requirements on the crushing fineness
For aquatic animals, pellet feed must meet certain water stability in order to meet the needs of animal feeding. In order to obtain high water stability of the feed, on the one hand, the fineness of the material made by fish food grinder is required to be sufficiently fine, and on the other hand, the feed raw materials are required to be mixed evenly. From the perspective of mixing uniformity, it is generally required that 95% of the material can pass through the 177-250μm screen.
In particular, for the production of particles with a diameter of 0.8 to 1.5 mm or less, the requirements for fineness of grinding are even higher. There is a basic principle when determining the fineness of feed grinding that the maximum particle diameter of the crushed particles cannot be larger than 1/3 of the ring die. This principle is related to the size of the ring die, which determines the crushing particle size of the feed.
Float and sink requirements on the crushing fineness
The feed of prawns and other aquatic animals not only requires the satisfaction of nutrition, but also their feeding habits determine whether to adopt the production design of sinking or floating feed. In general, a good comminution particle size makes it easier for the feed to form tight bonds, thereby increasing the density of the pellets and making the feed easier to sink.
In addition, the smaller pulverized particles made by fish food grinder have a larger surface area, which makes the particles more tightly bound during pelleting, thereby preventing the feed from flooding and collapsing, and improving the water stability of the feed. If the particles are not tightly combined, the feed will easily collapse in the water and affect the water quality.
The fish grinder machine crushing process is the focus of the design of the aqua feed factory, and it is also the difficulty in the design process. The selection of crushing process and fish food grindering equipment should be reasonably selected according to the types of aquatic animals, the characteristics of raw materials, the quantity of raw materials, and the quality requirements of aquatic feed.
Selection of fish feed grinding system
Therefore, when designing the crushing system in the fish feed production line, RICHI Machinery will assist customers to select suitable fish food grinder and crushing process according to different product quality requirements and different crushing particle size requirements, and design a reasonable air suction system. Under the premise of requirements, the cost of crushing should be reduced as much as possible to reduce the production cost of the entire fish feed processing.
