    Working Principle<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    The PG Roller Crusher operates based on a compression crushing mechanism between two counter-rotating rollers. Raw material is drawn into the crushing chamber through friction between the rollers and the material surface.<\/p>\n

    As the rollers rotate inward, the material is compressed and fractured under high pressure. The adjustable gap between the rollers determines the final output size, ensuring uniform particle distribution and minimal over-crushing.<\/p>\n

    This low-speed compression process reduces dust generation, vibration, and excessive fines compared to impact-based crushing systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

    1. Material Feeding – Bulk material enters the crushing zone from the top feed opening.<\/p>\n

    2. Roller Compression – Two counter-rotating rollers pull the material inward and applycompressive force.<\/p>\n

    3. Controlled Size Reduction – Material fractures progressively under pressure.<\/p>\n

    4. Gap Adjustment – Adjustable roller spacing defines final discharge size.<\/p>\n

    5. Stable Continuous Operation – The drive system ensures synchronized rotation foruninterrupted production. final output size.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
