What is Poultry & Chicken Feed Grinder
Our water drop poultry feed crusher machine is widely used as a chicken feed grinder machine for fine grinding of corn, soybean, and other raw materials like wheat, etc. In small and medium-sized poultry feed processing factories. water drop hammer mill chicken feed crusher machine is a machine aiming at crushing materials by the collision between the high-speed hammer and materials. The chicken feed crusher machine is suitable for grinding poultry feed, chicken feed, duck feed, goose feed, bird feed, broiler feed, layer feed etc. It is usually used together with poultry feed mixer to make poultry feed. The special water drop type design of livestock forage poultry feed crusher machine can ensure a larger space for grinding chamber and improves working efficiency by 40%.
Why a 2mm Screen is Crucial for Chicken Feed
Through years of experience in poultry feed processing, we know chickens have a very special digestive system. Because chickens have no teeth, they swallow food whole and use their gizzard (muscular stomach) to grind it. The output size of your chicken feed grinder machine directly affects how fast your chickens grow and lay eggs. For most poultry farms, grinding the feed through a 2.0 mm to 3.0 mm screen is the best choice. Let’s look at why fine grinding is so important.
Key Biological Benefits
- Better Nutrition Absorption: When corn or soybean is crushed finely to 2mm, it has a much larger surface area. This makes it very easy for the intestinal juices to mix with the feed. Chickens can absorb the protein and energy much faster, improving the feed conversion ratio (FCR) and saving your total feed cost.
- Protect the Intestines: Big, hard, and sharp pieces of grain can easily scratch the sensitive intestines of small chickens, leading to digestive diseases or inflammation. A uniform 2mm crushing size is soft and safe, keeping their digestive tract very healthy.
- Stop Feed Sorting: If the feed size is mixed with big and small pieces, chickens will pick out the big corn pieces and leave the fine vitamins or minerals behind. Grinding everything to a fine, even size forces them to eat a balanced nutrition in every single bite as you planned.


Recommended Screen Sizes for Different Poultry
We know that a poultry farm may have different chickens. To get the best feed result, you need to match the right screen size with your chicken’s age and breed. Here is a reference guide for you to choose the screen size for our poultry feed grinder machine:
| Chicken Age / Breed | Optimal Grinding Size (Screen Hole) |
| Chick (0-8 Weeks) | 1.0 – 1.5 mm |
| Pullet (8-20 Weeks) | 2.0 – 2.5 mm |
| Laying Hen (20+ Weeks) | 3.0 – 3.5 mm |
| Broiler Chicken | 2.5-3.5 mm |
| Bantam Breeds | 1.5-2.0 mm |
| Heavy Breeds (e.g., Jersey Giant) | 3.0-4.0 mm |
(Note: We can customize different sizes of screen meshes according to your farm’s exact requirements.)

Features and advantages of Poultry/Chicken Feed Crusher machine
- Precision 2mm Output: Guarantees uniform particle size to prevent feed sorting and protect the sensitive digestive tracts of chicks and layers.
- Safe & Dust-Free Operation: Features an advanced inset seal that eliminates dust overflow, protecting your poultry farm’s air quality.
- High-Efficiency Dual-Crush: The unique water drop chamber of the poultry feed grinder machine allows for a secondary crushing impact, boosting daily poultry feed output by up to 40% with the same energy consumption.
Working Principle of Chicken Feed Crusher Machine
- The raw material enters into grinding chamber of the poultry feed crusher machine through feed hopper and is held there until it is reduced to the size of the openings in the screen, and there are flailing hammers spinning very fast and close to a perforated screen.
- Under the drive of airflow, the ground material is moving along the rotor outer edge and has a continuous collision and friction against the hammer, toothed plate and sieve, then the material is ground. Once the particle size below the diameter of the screen holes, feed powder will pass through the screen.
- The feed particle discharges to the fan, and products are blown through the cyclone and delivered into storage bags under the suction force of working fan.
The materials ground by hammer blades with common teeth are usually of 1.0-1.5mm; and crushed with fine teeth are of 1-2.5mm.
