Screw Doser

CM series volumetric dosers are suitable for auto-proportional mixing of virgin materials, regrinds, master-batch or additives. A gear motor with gear ratio of 38: 1 or 75: 1 is coupled to a dosing screw of 12, 14 or 16mm diameter to give a total of six models with output. Ranging from 0.1~32kg/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. Features* 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.
