POWDER DOSING UNIT

SF SERIES

 

Powder dosing unit - sf series

The loss-in-weight feeders of the SF series are suitable for dosing free-flowing powders. The product enters into the hopper manually or through a butterfly valve. A built-in mixer helps to feed the screw so as to avoid problems during the downward movement of the material. A weighing system with load cell measures any weight variation in real time. The required throughput is obtained by changing the speed of the screw which is driven by a motor with inverter. A Siemens PLC controls from 1 to 8 dosing stations.

Technical Specifications

  • Stainless steel structure.
  •  Driven by a motor with inverter.
  • Control board with a S7 200 Siemens PLC.
  •  Gearmotor-driven mixer.
  •  Load cell installed in a protection box.
  •  Adjustable supporting feet.
  •  Complete with static mixer.
  •  Also available: Profibus or Ethernet interface.
  •  5.7” Siemens touch screen.

ACCESSORIES

    • +/- 1% precision on the weight of dosed material.
    • Real-time control of the throughput.
    • Easy setting of parameters.
    • Easy to clean.
    • Diagnostics, counters and data tracking.
