Stop Breathing Dust and Wasting Time on Manual Feeding
Imagine standing in a small barn or a backyard shed. You have a pile of corn kernels, dry straw, and maybe some soybeans. You need to make feed for your chickens, pigs, or cows. The old way is hard work. You shovel the grain into the machine by hand. Dust flies everywhere. It gets in your eyes, your nose, and your lungs. It is messy and unhealthy. Also, the machine gets clogged. The feed comes out in different sizes. Some pieces are too big for the baby chicks. Some are too small like flour. You have to stop and change screens all the time. It takes hours to finish a small batch. This wastes your energy and makes farming feel like a chore, not a business. You need a machine that does the hard work for you. You need a self-priming grinder that sucks the grain up automatically, crushes it evenly, and keeps your workshop clean.
What is a Self-Priming Corn Grinder?
This is not just a simple mill. It is a smart machine for small farms and home use. The “self-priming” part means it has a suction pipe. You put the corn or straw on the floor. You turn on the switch. The machine creates a vacuum. It sucks the material up the pipe and into the crushing chamber. No shoveling. No heavy lifting. It is fast and clean. Inside the machine, there is a high-speed rotor with teeth. These teeth hit the grain against a screen. The screen controls the size of the final powder. You can change the screen easily. If you want coarse grain for big cows, you use a big hole screen. If you want fine powder for chickens, you use a small hole screen. The machine crushes corn, dry straw, soybeans, wheat, and other grains. It is perfect for making mash feed or pellet feed. It uses electricity (220V for home light power or 380V for farm power). It is safe, quiet, and strong.
Key Features That Solve Your Problems
Automatic Suction Feeding System
You do not need to bend down or carry buckets. The suction tube lifts the material automatically. This saves a lot of labor. One person can run the whole feed processing line alone. It also stops dust from leaking out because the pipe is closed. This protects your health.
Dust-Free and High Efficiency
The crushing chamber is designed to keep air inside. The outlet has a bag or a cyclone to catch dust. This means your workshop stays clean. The motor is made of copper wire. It has high torque even at low speeds. It does not get stuck easily. The grinding speed is fast. You can process 80kg to 2000kg per hour depending on the model.
Uniform Particle Size
The screen ensures all the powder is the same size. This is very important for animals. If the feed is mixed with big and small pieces, animals pick the good parts and leave the rest. This is called “automatic grading.” Our grinder prevents this. Every bite is the same nutrition. Animals grow faster and stay healthy.
Multi-Purpose Crushing
Do not just crush corn. This machine handles many things.
- Grains: Corn, wheat, sorghum, barley, rice.
- Beans: Soybean, broad bean, pea.
- Straw: Dry corn stalk, peanut stalk, grass, hay.
- Others: Dry potato, ginger (for powder), even small insects (for protein feed).It is a true multi-functional tool for the farm.
Technical Parameters & Model Selection
We have different models for different needs. Check the table below to find the right one for your farm. We use a tooth-claw structure inside. This is better for fibrous material like straw.
| Model | Power (kW) | Capacity (kg/h) | Voltage | Dimensions (mm) | Weight (kg) | Screen Options (mm) |
|---|---|---|---|---|---|---|
| LY-15 | 1.5 | 80-100 | 220V | 450x650x700 | 17 | 1, 2, 3, 4, 6 |
| LY-19 | 2.2 | 100-130 | 220V/380V | 500x700x800 | 35 | 1, 2, 3, 4, 6, 8 |
| LY-23 | 3.0 | 150-270 | 220V/380V | 600x800x900 | 50 | 1, 2, 3, 4, 6, 8, 10 |
| LY-29 | 3-4 | 300-400 | 380V | 700x900x1000 | 75 | Customizable |
| LY-35 | 5.5-7.5 | 500-800 | 380V | 900x1100x1400 | 130 | Customizable |
| LY-45 | 15 | 1000-2000 | 380V | 1200x1200x1900 | 250 | Customizable |
Note on Screens: The default screen is 3mm. We give you 4 screens for free usually (1mm, 2mm, 4mm, 6mm). If you need very fine powder (like 80 mesh for flour), we can provide special fine screens. The rotor speed is about 3000-5000 RPM. It is very fast.
Real-World Usage Scenarios
Scenario 1: Small Backyard Chicken Farm
You have 50 chickens. You buy the LY-15 or LY-19 model. It runs on 220V home electricity. You put corn and soybeans on the ground. The machine sucks them up. You use a 3mm screen. The output is fine mash. You mix it with water or bran. The chickens eat it all. No waste. No dust in your yard. It takes 10 minutes to make feed for a week.
Scenario 2: Medium Pig or Goat Farm
You have 20 pigs or 50 goats. You need to crush dry corn stalks and corn grain together. You choose the LY-23 or LY-29 model. The 3kW motor has enough power to break the tough straw fibers. You use a 6mm or 8mm screen. The feed comes out coarse. The goats chew it well. It helps their digestion. The machine is heavy (50-75kg), so you put it on a concrete floor. It is very stable.
Scenario 3: Pellet Making Business
You want to make your own pellets to sell. You need very fine powder to make good pellets. You buy the LY-35 or LY-45 with a super-fine screen. The machine crushes the corn into flour. You mix it with vitamins and minerals. Then you put it into a pellet machine. The pellets are hard and smooth. Animals love them. Because the grinder is automatic, you can produce 1 ton of powder per hour easily.

Frequently Asked Questions
Q: Can I grind wet corn?A: No. This machine is for dry materials only. If you put wet corn in, it will clog the screen and block the motor. Please dry the corn first.Q: How often do I need to sharpen the teeth?A: The teeth are made of high-carbon steel. They last a long time. If you grind straw every day, check them every 3 months. If you only grind corn, they last 1 year. Replacing them is easy. Just unscrew the bolts and put in new ones.Q: Is it noisy?A: It makes a grinding sound, like a vacuum cleaner. It is not loud like a hammer mill. You can talk while it is running. We can add a sound cover if you need it to be very quiet.Q: Can I use it for wheat flour for baking?A: Yes. If you use a very fine screen (80-100 mesh), it works like a flour mill. But it is better for animal feed. For human food, you might need a specific stainless steel model to avoid metal contamination.
