Color masterbatch mixer/ Volumetric dosers :
Volumetric dosers are suitable for auto proportional mixing of the virgin, regrinds, masterbatch and additives for injection, extrusion or blow molding machines.
A stepper motor is used in this series, according to the set mixing proportion, the microprocessor accurately controls the rotation of the high precise dosing screw to squeeze out the materials with an accuracy of +/-1%.
The unit can be connected with molding machines and work synchronously to ensure the stability of the products.
APPLICATION
• Suitable for automatic proportional mixing of new materials, recycled granulation, color masterbatch or additives.
MOLDE FEATURES
● Everlasting data memorizer and settings storage.
● Use brushless DC motor and free from maintenance.
● Microprocessor control, intelligent and accutate in calculation.
● External signals can be directly interfaced with the control box.
● Dosing screws are chrome plated for durability.
● Unit is comprised of standard modules for ease of cleaning, disassembly and interchangeability.
● Three-tubes hopper magnet is equipped at the base of the single color doser to absorb metal impurities so to prevent the screw of moulding machine from damage.
● Single color doser takes base blender as an option to make blending more evently.
● Blender built-in a standard accessory for double color doser and it can meet client's need for double blending.
● Main material hopper is a standard accessory for double color doser. It is optional for single color doser.
WORKING PRINCIPLE
• According to the predefined addition of proportional parameters, through the conditions set by the all-digital computer control system automatically converted to the speed directly drive precision screw extrusion raw materials,its error value is not higher than 1%.
Different output of 0.1 to 100 kg per hour is available for customers to choose from
