Rubber Conveyer Belt Calendering Line

Rubber Conveyer Belt Calendering Line

Application
For producing rubber sheet, rubberizing carcass/fabric of conveyer belt

Scope
Φ610X1730 / Φ700X1800 / Φ800X2500 / Φ900X2800

Product Features

  • Small L/D ratio of rolls, enables small deformation in the action of the same calendering strength.
  • The roll surface and shaft journal are clamped and grinded on high precise CNC grinder, which enable roller with micron geometric tolerance.
  • The calender frame is casted with nodular cast iron, of high rigid and shock absorption.
  • The left/ right frame is processed and molding for once on CNC boring lathe, which ensures both frame the consistence of dimension.
  • Double row cylinder roller bearings of high precise are used to support the calender roll, which possess higher precise of rotation by contrast with self-aligning roller bearing.
  • Pre-bending systems are amounted at Roller#1,#3,#4, which keeps machine stable and the product with high precision.
  • Hardened gears are adopted for all gears inside gearbox. All the surfaces of gears are machined by grinder (made by Niles Germany) and of high precision. Rolls are kept in steady speed when rotating.
  • Encoder of high precision is adopted for detecting motor speed of roll. Speed closed-loop control system keeps roll hard mechanical property while enlarging load.
