Most Pulverizers have a housing with and internal rotors that spins at a high speed with either fixed or swinging knives, hammers, or rods/pins to size reduction using impact. Most have a screen discharge, where the product stays in the pulverizing chamber until it is small enough to fall through the screen. For finer particle sizes, Air classification mills are used, where the product stays in the pulverization chamber until it is light enough to flow out of the mill in an air stream.The different types of Pulverizers are:
