Rubber three-roll calender machine

Product Details

Key Specifications/Special Features:

  • Structure characteristics:

    • Rolls are made of chilled cast iron of vanadium and titanium alloy

    • Roll face is hard and anti-wear

    • For heating up or cool down, rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface

    • Machine is driven by DC motor with a wide range of speed adjustment Working linear speeds can be steplessly regulated within the fixed range for different applications

    • Rolls are equipped with lubrication failure alarm device, as well as nip display and speed display

    • Rolls can be arranged in L and I forms

    • Top roll has camber that can eliminate bending impact on the roll in working process

    • Thus, it is possible to make products with same thickness along axial direction

    • Transmission system adopts hard gear speed reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life

    • Machine is equipped with emergency device

    • When an emergent accident occurs, calendar will be immediately stopped to open the roll space so as to protect the operator and equipment

  • Applications:

    • Machine is chiefly applied to put rubber on fabric, canvas or other fabrics to rubberize fabrics or to make rubber sheets
