Working Principle
The 9F-70 Forage Chopper operates on a sophisticated hammer-mill principle that combines impact, shear, and compression forces to efficiently process agricultural materials into uniform feed particles. Understanding this working mechanism helps operators optimize machine performance and achieve the best possible results.
Material Feeding: Raw agricultural materials such as corn stalks, straw, or hay are introduced into the machine through the cylindrical feeding system. This feeder is designed to maintain a consistent flow rate while preventing material bunching or bridging that could interrupt processing.
High-Speed Impact: Once inside the crushing chamber, materials encounter the rapidly rotating rotor spinning at 1800 revolutions per minute. The 64 hammer blades mounted on the rotor strike the material with tremendous force, shattering it into smaller pieces upon impact. This high-speed impact is the primary mechanism for size reduction.
Secondary Processing: As material is beaten against the chamber walls and stationary anvil bars, additional shear and compression forces further reduce particle size. The material circulates within the chamber until particles are small enough to pass through the perforated sieve at the bottom.
Discharge: Properly sized particles fall through the sieve openings and are discharged through the collection outlet. Oversized particles continue to be processed until they achieve the desired size, ensuring uniform output quality. The adjustable sieve opening size allows operators to control final particle dimensions based on specific feed requirements.

Customer Reviews
We purchased the 9F-70 two years ago for our dairy farm in Minas Gerais, and it has been a game-changer for our operation. Previously, we struggled to process enough feed for our 200-head herd, often spending long hours with smaller equipment. This machine handles everything we throw at it – corn stalks, sugarcane tops, and even some of the thicker sorghum stalks that used to jam our old chopper. The diesel engine runs smoothly and hasn’t required major repairs. Our feed costs have decreased by about 30% since we started using properly processed forage.
As the manager of a commercial feed processing facility in Bavaria, I need equipment that can handle high volumes consistently. The 9F-70 has performed admirably, processing around 150 tons per week during peak season. The build quality is solid, and the 64 hammer configuration produces very uniform particle sizes which our customers appreciate. One minor issue is that the machine is quite loud during operation, but that’s expected with this type of equipment. The after-sales support from Brazil Agricultural Balers has been responsive, though parts delivery to Europe takes some time. Overall, good value for the price point compared to European brands.
Our cooperative serves 45 small-to-medium farmers in the Jalisco region, and we needed something powerful enough to justify the investment. The 9F-70 processes not only corn and sorghum but also sugarcane waste which is abundant here. The capacity of 5-20 tons per hour means we can serve all our members within a reasonable timeframe. The machine is straightforward to operate – we trained three of our staff in about half a day. We’ve had it for 18 months now with no major issues, just routine maintenance. The Brazilian company provided detailed manuals in Spanish which helped enormously.
We use this machine to process agricultural residues for our biomass power generation facility. The 9F-70 handles rice straw, wheat stalks, and corn cores quite effectively. The output particle size is consistent enough for our combustion requirements after we adjusted the sieve. The machine is heavy and requires proper foundations, but it’s built like a tank. Our only concern is that getting replacement parts in China can take time, so we keep a stock of critical wearing parts on site. The Chinese-language technical support could be improved, but the English support via email is quite good.
I run a 500-head beef cattle operation in Texas, and we process a lot of crop residues from neighboring farms. The 9F-70 has exceeded my expectations in terms of durability and throughput. We were initially skeptical about a Brazilian machine, but the build quality matches or exceeds American equipment at a significantly lower price point. The diesel engine is easy to maintain, and I’ve been able to do most repairs myself using the detailed parts manual. Shipping and customs were handled smoothly by the company. Would recommend to other ranchers looking to improve their feed efficiency without breaking the bank.
As an agricultural engineer who advises farms in the Netherlands, I’ve evaluated many forage processing machines. The 9F-70 from Brazil Agricultural Balers offers an interesting combination of high capacity and competitive pricing. My clients who purchased it appreciate the simple design which makes maintenance straightforward – something that’s increasingly important given the shortage of qualified technicians here. The machine performs well with grass silage and alfalfa. The dust collection could be better designed for European environmental standards, but this can be addressed with aftermarket solutions. Good technical documentation makes my job easier when helping clients with troubleshooting.
