screen should be 0.5 inches (≈ 12 to 14 mm) for size reduction of cereal grains. The velocity or tip speed of the hammers is critical for proper size reduction. Tip speed is calculated by mul-tiplying the rotational speed of the drive source (shaft rpm) by the circumference of the hammer tip arc (For-mula 1). Formula 1: feet per minute = πD ...

Mechanism of size reduction · Impact – this involve hammer or bar at high speed (hammer mill). Particle Size 50-8,000 µm. · Compression- particle crushed b/w rollers by the application of force (roller mill). Particle Size 50-10,000 µm. · Cutting – the material cut by a sharp blade (cutter mill), Particle Size 100-80,000 µm.

Hammer milling parameters such as screen size, blade selection and rotor speed can be optimized for each application, depending on the equipment used. The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm. Hammer mills tend to yield less than 25% of particles below 150 μm.

Hammer Mill has various advantages: It produces specified top size without the need for a closed-circuit crushing system. Produces relatively numerous size distributions with a minimum of fines due to self-classification. It has high reduction ratio and high capacity whether used for primary, secondary or tertiary grinding.

Hammer Mills for Size Reduction . Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill's grinding chamber.
