The 9YDB-90 silage baler wrapper machine is an integrated round bale pressing and wrapping machine with an hourly output of 55-60 bales. It automatically finishes feeding, high-density compressing, film wrapping and bale discharging in one continuous process, forming firm bales with a standard size of 90*90cm.
This machine suits a wide range of raw materials for livestock feed production. Major applicable materials include fresh corn stalks, napier grass, alfalfa, ryegrass and other green pasture forages. It also handles crop residues like wheat straw, rice straw, sorghum stalks and peanut vines. Chopping stalks into short segments beforehand helps boost bale compactness and fermentation quality, supplying stable preserved feed for cattle, sheep and large-scale breeding farms.

How does the silage baler wrapper machine work?
- Feeding stage: Green grass, corn stalks or straw are sent into the large hopper, and the internal conveyor steadily transports raw materials into the compression chamber. Spilled materials are recycled by the scraper recovery device to avoid waste.
- Compression baling stage: Multiple heavy-duty rollers rotate and squeeze the loose forage continuously, exhausting air to form a tight, solid round bale of fixed size and weight.
- Transfer & wrapping stage: Once the bale is shaped, it is conveyed to the wrapping station. Two wrapping arms rotate evenly and wrap multiple layers of silage film to form a fully airtight seal.
- Discharging stage: After wrapping finishes, the finished sealed silage bale is automatically ejected. The machine immediately starts the next round of feeding and baling for non-stop continuous operation.
9YDB-90 silage baler wrapper machine advantages
- High Production Capacity – The machine can produce 55–60 bales per hour with a processing capacity of over 23 tons per hour, making it ideal for large-scale farms and silage processing plants.
- Large Bale Size – It produces large 90×90 cm silage bales weighing 300–430 kg, reducing the number of bales required for storage and lowering transportation costs.
- High-Density Compression – Equipped with 28 or more compression rollers, the machine creates dense and compact bales, improving silage fermentation quality and extending feed preservation time.
- Dual-Arm Wrapping System – The dual-arm automatic wrapping design ensures faster and more uniform film coverage, providing better sealing performance and minimizing nutrient loss during storage.
- Fully Automated Operation – Feeding, compressing, baling, and wrapping are completed automatically, reducing labor requirements, improving efficiency, and minimizing operational errors.
- Material Recovery Design – The machine features a material recovery system that collects scattered forage, reducing waste and improving raw material utilization.
- Suitable for Various Forage Materials – It can process corn silage, pasture grass, alfalfa, wheat straw, rice straw, and other forage crops, making it a versatile solution for livestock farms.
- Reduced Storage and Feed Loss – By producing tightly wrapped and sealed silage bales, the machine helps prevent mold growth, reduces nutrient loss, and ensures long-term feed preservation.
How to choose the right silage baler wrapper machine?
We provide four sizes of integrated silage baler wrapper machines including 55, 60, 70 and 90 types, differentiated by bale size, output, power and load capacity. Your breeding scale, daily forage yield, tractor power and transportation conditions are core factors to decide the proper model.
- Model 55 & 60 : Small lightweight units, low power demand, small bale weight. Perfect for small family farms, scattered pastures and users with limited traction power; easy to move and feed livestock with small batches.
- Model 70 : Medium balanced configuration with moderate processing efficiency and bale density. Best match for medium-scale cattle and sheep farms with steady daily silage production, balancing cost and working capacity.
- Model 90: High-capacity heavy-duty machine, largest bale dimension, hourly output over 23 tons. Designed for large breeding bases, commercial silage processing plants and bulk field baling tasks; fits thick corn stalks and large-volume green forage raw materials.
Additional reference tips: Larger bales from the 90 model require bigger transport trucks and sufficient storage space; wet, thick stalk materials gain better compression and fermentation effect on 70 and 90 high-density machines.
