Animal Feed Grinding Machine

Animal Feed Grinding Machine Price And Parameter

How to choose suitable animal feed grinding machine

Animal feed grinding machine is mainly used to pulverize various feeds and various roughages. The purpose of feed pulverization is to increase the surface area of ​​the feed and adjust the particle size, increasing the surface area to improve the palatability, and it is easy to contact with the digestive juice in the digestion edge, which is conducive to improving the digestibility and better absorption of feed nutrients.

Adjusting the particle size by animal feed grinding machine ——on the one hand, it reduces the energy consumed by livestock and poultry chewing, and on the other hand, it is more convenient for transportation, storage, mixing and granulation, and the efficiency and quality are better.

Select the animal feed grinder machine according to the production capacity

Generally, the manual and nameplate of the animal feed pulverizer contain the determined production capacity (kg/hour) of the pulverizer, but several points should be noted:

1. The stated production capacity refers to the output in a specific state, such as a grain feed hammer mill grinder, which means that the crushed raw material is corn, its moisture content is safe for storage (about 13%), and the sieve aperture diameter is 1.2 mm. Because corn is a commonly used grain feed, the sieve with a diameter of 1.2 mm is the smallest sieve hole commonly used, and the production capacity is small at this time, which takes into account the more difficult state in production.
2. The production capacity of the selected animal feed grinding machine should be slightly larger than the actual required production capacity, otherwise it will increase the wear of the hammer and the air leakage of the air duct, which will lead to a decrease in the production capacity and affect the continuous production and supply of feed.

Select the animal feed grinding machine according to the crushing raw materials

For crushing grain feed, the top feeding animal feed grinding machine is optional. For crushing bran and wheat feed, claw crusher can be selected. If you require good versatility, mainly crushing grains, and taking into account the cake and straw, you can choose a tangential feed hammer mill.

To crush mineral feeds such as shells, a sieveless crusher for shells can be used. If it is used as the pretreatment of premixed feed, if the particle size of the product is required to be very fine and can be adjusted according to the needs, a special sieveless animal feed grinding machine should be used.

Select the animal feed grinding machine according to the discharge method

There are three ways to output the crushed products through the discharge device: self-weight blanking, negative pressure suction and mechanical conveying. Small single machine mostly adopts self-weight cutting method to simplify the structure. Most of the medium-sized animal feed grinding machines are equipped with a negative pressure suction device.

The advantage is that it can absorb the moisture of the finished product, reduce the humidity in the finished product and facilitate storage, improve the pulverization efficiency by 10% to 15%, and reduce the dust in the pulverizing chamber.

Select the feed grinder according to the matching power

Both the machine manual and the nameplate contain the power kilowatts of the electric motor of the animal feed grinding machine. It often indicates not a fixed number but a certain range.

There are two reasons for this:

• First, the power required for different types of crushed raw materials is quite different. For example, under the same working conditions, the power of crushing sorghum is - times greater than that of crushing corn.
• Second, when changing to different sieve holes, the load of the pulverizer has a great influence. Therefore, when the 9fq-60 type pulverizer uses a sieve with a diameter of 1.2 mm, the motor capacity should be 40 kilowatts. When changing to a sieve with a diameter of 2 mm, a 30-kilowatt motor can be used, and a sieve with a diameter of 3 mm is a 22-kilowatt motor, otherwise it will cause a certain degree of waste.

Select the animal feed grinding machine according to the energy saving situation

The energy consumption of the animal feed grinding machine is very large, and energy saving should be considered when purchasing. According to the standards of the relevant departments, when the hammer mill crushes corn with a sieve with a mesh diameter of 1.2 mm, the output per kilowatt-hour of electricity shall not be less than 48 kilograms.

The output per kWh of domestic hammer mills has greatly exceeded the above regulations, and the high-quality ones have reached 70-75 kg/kWh. The power of the pulverizer is marked on the machine manual and the nameplate of the pulverizer's matching motor in kilowatts. The indicated power kilowatts is often not a fixed number but a range.

There are two reasons for this. One is that the power required for crushing different types of raw materials is quite different. For example, under the same working conditions, the power of crushing sorghum is twice as large as that of crushing corn.

Second, when changing to different sieve holes, it has a great influence on the load of the animal feed grinding machine.

According to the standard, when the animal feed grinding crushes corn with a sieve with a diameter of 1.2 mm, the output per kilowatt-hour of electricity shall not be less than 48 kilograms. High-quality products have reached 70 kg to 75 kg per kilowatt hour.

Select animal feed grinding machine according to dust and noise

Dust and noise in feed processing mainly come from pulverizers. These two indicators should be fully considered when selecting models.

If a animal feed grinding machine with high noise and dust is selected as a last resort, noise reduction and dust-proof measures should be taken to improve the working environment and benefit the health of feed grinding machine operators.

Methods to reduce maintenance costs with careful animal feed grinding machine selection

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.

1. Selecting the screen area.

   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.

2. Selecting the hammer pattern.

   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.
   

3. Setting the tip-to-screen clearance.

   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.
   

4. Setting the tip speed.

   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.

Several different types of livestock and poultry have requirements for feed particle size

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:

Chicken feed particle size requirements

1. Young chickens: less than 1.0 mm in diameter
2. Medium chicken: 2.0 mm in diameter
3. Adult chicken: 2.0～2.5mm in diameter

Pig feed particle size requirements

1. Suckling piglets: less than 1.0 mm in diameter
2. Piglets: 1.0 mm in diameter
3. Early fattening: 1.0～1.2mm in diameter
4. Late fattening period: 1.2～1.5mm in diameter

The particle size requirements of dairy cow feed

1. Suckling calves: less than 1.0 mm in diameter
2. Young cattle: less than 2.0 mm in diameter
3. Calf: Diameter less than 2.2 mm (6.0 mm for pellets)
4. Adult dairy cows: less than 2.5 mm in diameter (15.0 mm for pellets)
