    • The hammer mill is designed for efficient size reduction of powders and granules. Material is evenly fed into the milling chamber through a rotary valve, where high-speed rotating blades apply impact and shear forces to achieve fine and uniform particles with a milling precision of up to 200 mesh.

    Features
    • Dead-corner-free milling chamber for easy cleaning and maintenance
    • Modular design adaptable for various process requirements
    • Equipped with automatic protection against overheating and overloading
    • Adjustable rotor speed ranging from 2500–6000 RPM
    • Quick disassembly of rotor and screen for easy cleaning and safe operation
    • Controlled screening delivers uniform particle size and steady throughput

    The hammer mill is ideal for milling dry, brittle, and crystalline materials such as active pharmaceutical ingredients (APIs), food additives, dyes and pigments, and herbal materials. Once fed into the chamber, materials are rapidly reduced under the impact of high-speed rotating hammers, resulting in fine and uniform output.

    The CFJ hammer mill features a more precise structure and a superior hygienic design. It operates on a combined high-speed shearing and centrifugal impact principle, producing finer, more consistent particles. The system is easy to dismantle for cleaning and fully compliant with GMP standards.

    The milling equipment is constructed from 304 or 316L stainless steel, with a highly polished internal surface (Ra ≤ 0.4 μm) and dead-corner-free design. The quick-release structure allows easy cleaning and product changeover, fully meeting GMP requirements for pharmaceutical and food applications.

    The hammer mill is designed for moderate-speed operation with a compact structure that minimizes heat generation. When equipped with a dust extraction system, airborne particles are effectively controlled. For heat-sensitive materials, a low-temperature milling or air-cooling configuration can be provided to prevent degradation.
