10-12T/H Round Bale Chopper for sale Italy

Po Valley Dairy and the Sorghum Challenge

The Po Valley in northern Italy is one of Europe's most productive agricultural regions, known for Parmigiano-Reggiano and Grana Padano cheese production. Dairy farms in this region typically house 150-500 cows and feed high-forage rations to produce milk with the right protein and fat content for long-aged cheeses.

Sorghum has become increasingly popular as a forage crop in recent years because it tolerates heat and drought better than maize, and Italian summers have been getting hotter and drier. However, sorghum bales present unique challenges: the stalks are woody and fibrous, and the bales are often baled at higher densities than grass silage or alfalfa.

The Cremona farm grows its own sorghum on 180 hectares, harvesting it in late August and baling it into 1.6m round bales at approximately 45-50% moisture. They also purchase dry alfalfa bales (12-15% moisture) from producers in Emilia-Romagna to boost protein content in the ration.

The feed formula is roughly 60% sorghum silage, 30% alfalfa hay, and 10% concentrate (corn meal, soybean meal, minerals). The farm owner was frustrated with his old bale breaker because it could not produce a consistent chop size, and cows were sorting through the feed, leaving the longer sorghum stalks behind.

He had been searching for a round bale chopper for sale that could handle both the wet sorghum bales and the dry alfalfa bales without adjustment. The RICHI YPPK-2800, with its larger 2.05m capacity and 90kW motor, was a perfect fit for his operation.

He ordered two YPPK-2800 round bale chopper units—one dedicated to sorghum silage, the other to dry alfalfa—allowing him to blend the two forages directly into his TMR mixer without cross-contamination.

The YPPK-2800 for Italian Sorghum and Alfalfa

The primary materials processed daily at this Italian dairy include:

• Sorghum silage bales (45-50% moisture): Sorghum stalks are woody and contain a pithy center that can be challenging to chop. The 48 hammers on the YPPK-2800 provide the impact frequency needed to break down the pith, while the damping plate prevents the bales from spinning in place.
• Dry alfalfa bales (12-15% moisture): Alfalfa is leafy and tends to produce dust when processed too aggressively. The YPPK-2800 runs alfalfa at a slightly lower rotor speed via adjustable VFD to preserve leaf matter, which contains most of the protein.
• Wheat straw bales (10-14% moisture): Purchased for dry cow rations and bedding. The YPPK-2800 processes straw at 10-12 tons per hour at the coarser bedding setting 30-40mm.

The target output size for sorghum and alfalfa is 20-30mm. This particle size is ideal for Parmigiano-Reggiano production because it provides the right fiber structure for rumen health without allowing cows to sort out long pieces.

Grabbing Woody Sorghum Bales

Sorghum bales are notoriously difficult to process because the stalks are stiff and the bales are dense—often weighing 800-900kg each. When a standard bale chopper's hammers strike a sorghum bale, the impact often just pushes the bale backward rather than tearing into it. The rotor spins, the bale bounces, and the operator has to push harder, risking injury.

The YPPK-2800 round bale chopper solves this with its damping plate, a stationary surface positioned precisely inside the crushing chamber. For Italian sorghum, this feature is critical:

The damping plate creates a pinch zone that holds the bale against the hammer tips just long enough for the hammers to penetrate the surface. Once the hammers have established a bite, the gear external chain rotary cutting at the feed intake helps pull the rest of the bale into the chamber. The result is consistent, self-feeding operation with minimal operator intervention.

For the Cremona farm, the damping plate means:

• No more manual pushing of bales into the rotor
• 40% faster throughput on sorghum compared to the old machine
• Reduced power spikes because the bale feeds evenly

48 Hammers for Woody Sorghum Fibers

The YPPK-2800 round bale chopper is equipped with 48 hammers—significantly more than the YPPK-2600's 36. This higher hammer density provides two advantages for sorghum processing:

1. More impacts per revolution: Each hammer strikes the material more frequently, breaking down the woody fibers more effectively.
2. Better coverage across the rotor width: The 48 hammers are arranged in a staggered pattern that covers the full 2.8m chamber width, ensuring that no material passes through unchopped.

The hammer construction is the same as other YPPK crusher machine models but scaled up:

• Base material: 65Mn manganese steel, heat-treated quenched to achieve a surface hardness of 45-50 HRC. This hardness allows the hammers to cut sorghum fibers rather than just crushing them.
• Wear surface: Tungsten carbide overlay welding applied to the working tips. Sorghum contains silica bodies that are highly abrasive, but the carbide layer resists wear effectively. The farm owner reported that after processing 900 sorghum bales approximately 700 tons, the hammer tips showed less than 3mm of wear.

What Happens to the Chopped Forage: Parmigiano-Reggiano Dairy Rations

Once the round bale chopper reduces the sorghum and alfalfa to 20-30mm, the farm uses the material in several specific ways:

1. Lactating cow TMR total mixed ration: The chopped sorghum silage 20-25mm and chopped alfalfa 20-25mm are blended with high-moisture corn silage, protein concentrate, and minerals. The uniform particle size ensures that each mouthful contains the correct fiber length, which is critical for rumen function in high-producing Holsteins. The farm's milk production increased by approximately 2.5 liters per cow per day after switching to the YPPK-2800—mostly because the cows stopped sorting and ate everything in the bunk.
2. Dry cow ration: For dry cows the 60-day period before calving, the farm uses a higher-fiber mix with more sorghum and less concentrate. The 25-30mm chop size provides the scratch factor needed to maintain rumen health during the dry period.
3. Youngstock starter: Heifers from 6-12 months receive a mix of chopped alfalfa 20mm and concentrate. The smaller particle size is easier for developing rumens to digest.
4. Bedding for calving pens: When processing wheat straw at 30-40mm, the output is fluffy and absorbent—ideal for calving pens where cleanliness is critical for newborn calf health.

A Smart Investment for Po Valley Dairy Farms

The round bale chopper for sale Italy represented by this Cremona dairy installation proves that heavy-duty Chinese equipment can handle the challenging sorghum and alfalfa processing requirements of Italian dairy farming. The YPPK-2800 processes dense sorghum bales that defeat standard shredders, delivers consistent 20-30mm output for high-end Parmigiano-Reggiano rations, and withstands daily commercial use without excessive maintenance.

For any Italian dairy farmer, custom feed processor, or biogas operator currently struggling with inconsistent chop quality and unreliable bale processing equipment, the YPPK series offers a heavy-duty, cost-effective solution. The ability to purchase two units for the price of one European machine provides operational redundancy and the flexibility to process multiple forage types simultaneously.

Contact RICHI Machinery directly for a site assessment, to request hammer samples for sorghum testing, or to arrange a conversation with the Cremona farm owner about his experience. The return on investment is clear: less sorting waste, higher milk production, healthier cows, and machines built to last through many Italian harvest seasons.
