Rubber Three-roll Calender

Rubber Three-roll Calender

Application
For one-side rubberizing fabric, canvas and other textile, and rubber sheet calendering for inner layer of tyre

Scope

Product Features

  • The rolls are made from alloy chilled cast iron, sturdy and durable.
  • 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 bearing of high precise is used to support the calender roll, which possess higher precise of rotation by contrast with self-aligning roller bearing.
  • Pre-loading systems are amounted at Roll#1, 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.
