    Please read this manual carefully before installation and using of the machine to prevent damage or personal injuries. The SCM-E series "Standard" volumetric dosers are suitable for auto-proportional mixing of new materials, regrinds, master batch and additives. A carbon-brush motor is used in this series. The operator controls the precise dosing screw by setting its rotation speed to extrude materials with an accuracy of ±1％.

  • Page 8: Coding Principle

    1.1 Coding Principle 1.2 Feature Standard configuration 1) Motor rotating speed and plasticizing time can be adjusted simply and directly. 2) High and low potential starts can be selected for IMM connecting signal 3) Fixed 60-second output testing. 4) Machine halts and sounds alarm when motor faults. 5) Use carbon brush motor, the carbon can be replaced at fixed period.

    Structure Characteristics and Working Principle 2.1 Main Functions The SCM-E series "Standard" volumetric dosers are suitable for auto-proportional mixing of new materials, regrinds, master batch and additives. A carbon-brush motor is used in this series. According to the set mixing proportion, the microprocessor accurately controls rotation of the high precise dosing screw to squeeze out materials with an accuracy of ±1％.

  • Page 16: Working Principle Of Two-Color Doser

    2.2.2 Working Principle of Two-color Doser Two-color doser combines two dosing units with a blending system. It can be used to convey two color additives at the same time. Choose different kinds of dosing units according to additive usage. Each dosing unit is controlled by separate system, suitable for accurate dosing of virgin material, regrind, materbatch or other additives.
