  • Mixing capacity: 2-60g
  • Drum temperature: normal temperature ~ 300鈩
  • Heating method: electric heating (new process design, electric heating of open mill drum, automatic constant temperature)
  • Temperature accuracy: 卤2鈩 (The thermostat adopts a high-precision PID intelligent microcomputer control system, with an internal constant automatic calculation function, which is more accurate than manual setting and saves time. It has an over-temperature function to protect machinery and production materials)
  • Drum speed: 0-19 rpm adjustable
  • Roller speed ratio: 1:1.25 (speed ratio can be customized according to customer needs)
  • Roller size: 褎76mm脳L 300mm (high hardness surface hard chrome plating, no sticking, no delamination)
  • Roller spacing: 0.1~5mm adjustableProtection device: Multiple touch-type emergency stops (with reverse function, humanized design, no work-related injuries to operators)
  • Motor: 0.3KW 1 set (new process design, mechanical structure adjustment, the output torque is as large as the traditional process mechanical transmission 1KW, achieving the purpose of energy saving)
  • Power: 1KW
  • Volume: (W脳D脳H) 1100脳400脳1180mm. The volume is smaller than that of traditional processes with the same functions.
  • Roller lubrication: The excellent wear-resistant bearing contact area and traditional copper sleeve extend the service life by 2/3.
  • Mechanical structure: steel plate (lighter weight, smaller volume, higher mechanical strength and better toughness than traditional cast iron)
  • Power supply 5鈭, AC380
  • Weight: about 160kg
