The process of grinding or crushing a solid material into fine powder or particles. Pulverization increases surface area, which increases reaction rates and improves mixing. Used in sample preparation for analysis, ore processing, and pharmaceutical manufacturing.
Properties & Characteristics
Pulverisation is the mechanical size reduction of a solid material into a fine powder by crushing, grinding, or milling. Methods include: ball milling (steel balls in rotating drum), jet milling (high-speed air jets), hammer milling, and cryogenic grinding (brittle materials cooled with liquid N₂). Pulverisation increases surface area dramatically, affecting solubility, reactivity, and dissolution rate of the material.
Uses & Applications
Pulverisation is used in: pharmaceutical manufacturing (micronisation of drug particles to improve bioavailability), pigment processing, cement production, mineral processing (ore grinding for extraction), food processing (flour milling, spice grinding), and in ceramic powder preparation for sintering.
Safety Information
Pulverisation creates fine dust particles (respirable fraction < 10 μm, alveolar fraction < 2.5 μm). Fine dust of combustible materials (metal powders, grain, coal, pharmaceutical actives) is a dust explosion hazard. Mineral dust (silica, asbestos, limestone) causes chronic lung disease. All pulverisation operations require dust collection systems and respiratory protection.
