Hammer Mill Corn

Corn is tricky – high starch, medium fiber, and moisture can change a lot. So we built the Lvlon series corn hammer mill to handle corn grain, corn cobs, and corn stalks. It's widely used for pig, chicken, and ruminant feed, also for corn flour and ethanol production.

Particle size control & feed digestibility

 

Different animals need different corn grinding particle size. We follow animal nutrition recommendations and offer matching screen sizes. Check the table:

Animal type	Recommended size (mm)	Recommended screen hole (mm)	Feed digestibility note
Piglets, weaners	0.8–1.2	2.0–2.5	Each 0.2mm finer → ~1.5% better digestibility
Finishing pigs	1.2–1.5	3.0–4.0	Avoid too fine – risk of stomach ulcers
Layers, broilers	1.0–1.5	2.5–3.5	Too coarse hurts digestibility, too fine affects eating
Ruminants (cattle, sheep)	2.0–4.0	5.0–8.0	Needs coarse particles to help rumination

 

Our Lvlon series comes standard with two screens (you pick the hole sizes). Screen mesh size options: 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, 8.0, 10.0 mm. Change them in seconds – no tools needed.

Energy efficiency – real-world energy consumption per ton

 

Corn grinding usually eats up the most electricity in a feed mill. We tested our LV-420 (11 kW, 4mm screen, corn at 14% moisture).

Energy consumption per ton: 14.2 kWh/t

That's noticeably better than the industry average of roughly 18–20 kWh/t.

Run it 2000 hours a year (output ~1500 kg/h), and you save about 11,000–17,000 kWh compared to typical machines.

 

Temperature control – preventing starch gelatinization

 

Corn starch starts to gelatinize above 60°C – that hurts digestibility. Our design keeps things cooler:

• Large curved screen area for better airflow
• Optimized rotor and hammer arrangement to reduce useless friction
• Real test: after one hour of continuous grinding (4mm screen, room temp 25°C), discharge temp ≤52°C.
• Temperature rise ≤27°C – much lower than the usual 35–40°C you see elsewhere. That's real starch gelatinization prevention in action.

* Output numbers based on corn grain, 14% moisture, 4mm screen. For corn cobs, expect about 60–70% of that; for stalks, about 40–50%.

Every machine comes with a Shakron dust collector and two screens. We also offer diesel hammer mill or gasoline engine versions if you need them.

For comparison, ordinary carbon steel hammers (~35 HRC) last about 196 tons. Our alloy hammers give 77% longer life – less downtime, fewer changes.

Look & feel – any paint color, your own logo, nameplate, decals.

Power source – electric motor / gasoline engine / diesel hammer mill.

Special needs – screen for corn cob grinding, magnetic separator, extended feed inlet.

Warranty – one year warranty on the whole machine. Wear parts like hammers have different coverage based on usage.

Spare parts – after warranty, all parts at factory cost.

We deliver to Southeast Asia, Africa, South America – you name it. If you do corn processing in South America, need animal feed processing equipment in Africa, or look for agricultural machinery in Southeast Asia, we've got you covered. Just ask.
