PP plastic masterbatch hydroponic auto doser

MCM series volumetric dosers are suitable for auto-proportional mixing of virgin materials, regrinds,   master- batch or additives. A gear motor with gear ratio of 50 : 1 or 30:1 is coupled to a dosing screw of 16, 20 or 25mm diameter to give a total of six models with output. ranging from 0.1~38kg/hr. Double color dosers can be assembled from two single color dosers if required. Five components automatic mixing can be realized if customers adopt four color dosers.

• Dosing screws are chrome plated for durability.


• Unit is comprised of standard modules for ease of cleaning, disassembly and interchangeability.


• Blender is a standard equipment for double color doser to make the material evenly mixed, while also a optional equipment for single color doser to do so.


• Main material hopper is a standard equipment for double color doser. It is optional for single color doser.


• External signals can be directly interfaced with control box.The current operation mode can be recorded, unaffected by power failure so operation would be returned to normal when power is on.


• Forced material cleaning is convenient to replace masterbatch.


• Applicable on extrusion machines, just need to make a few wire replacements.

• Rotating speed can be automatically adjusted according to extruder processing speed, which maintains the fixed proportion of masterbatch.


• 50 units of parameter recipes are available for permanently recording the period of material discharging and finished products weight (for extruder, it is max. throughput per minute).


• Use brushless DC motor and free from maintenance.


• Both master blockage and overload can be detected, then machine will halt and sound alarm.


• Based on customers demand, some mold cycles can be set to add additives periodically so that micro-metering can be achieved.
