Straw Hammer Mill – High-Efficiency Straw & Grass Grinding Solution
Type: Straw & Grass Crushing Equipment
Capacity Range: 1 – 10 t/h
Power Range: 37 – 220 kW
Application: Corn straw, broomcorn straw, peanut vine, bean stalk, hay, and other straw/grass materials
Product Overview
The SYFP66 Series Straw Hammer Mill is a heavy-duty grinding solution specifically engineered for processing straw and grass materials. With top-mounted inlet design, robust steel plate construction, and direct drive transmission, this hammer mill delivers efficient, reliable performance for feed processing, biomass preparation, and agricultural residue treatment.
Key Product Features
1. Top Inlet Design
The feed inlet is positioned on the top of the machine, allowing for smooth material entry and consistent feeding. This design is particularly suitable for long-fiber materials such as straw and grass.
2. Durable & Wear-Resistant Construction
The grinding chamber is fabricated from thick steel plates with double wear plates at material contact points. All wear parts are replaceable, significantly extending service life and reducing maintenance costs.
3. Direct Drive Transmission
The motor and rotor share a common base, connected via coupling for direct drive. This design minimizes power loss, ensures efficient transmission, and simplifies installation and alignment.
4. Dynamic Balancing & Reversible Rotor
The rotor undergoes strict dynamic balance calibration and can operate in reverse, extending hammer life through symmetrical hammer arrangement. This design ensures smooth operation, reduced vibration, and high efficiency.
5. Simple, Safe & Reliable Operation
The machine features a straightforward design for easy installation and operation. Low shock and vibration levels, combined with safety features, ensure stable and reliable long-term performance.
