Granule Doser Pellet Blender Powder Mixing Plastic Mixer

XGB-200 plastic mixing granules mixing power mixer plastic weighing gravimetric blender




 

STANDARD CONFIGRAUTION
♦  The microscale metering accuracy is ±0.1% when all materials are blended through gravity;
♦  Auto calibration function which is performed every time after material weighting ensures best proportioning accuracy;
♦  Up to 100 recipes can be stored for future use;
♦  Have alarm history record function;
♦  SGB-600 and models below are directly mounted on machines;
♦ For XGB-1200 and models above, floor stand is the standard supply (equipped with floor stand, material storage tank and pneumatic discharge valve);
♦  With function of material auto-suction control;

ACCESSORY OPTION
♦  Hopper low material level sensor is optional for advance warning when lacking materials;
♦  Floor stand, pneumatic discharge valve, storage bin and suction box should be equipped for floor mounting. (Applicable for XGB-600 and models below);
♦  Vacuum generator XVG and central hopper receiver XHR-U-ST are optional;
♦  Microscale metering valve is optional for XGB-40/200/600 to meter materials with proportion of 0.2%-0.5%;
♦  Function of recycled material auto-compensation is optional ( recycling hopper should option with low level switch).Aberration compensation can be automatically calculated according to the discharging amount of recycled materials.

RELATIVE TO BATCH CAPACITY
Ratios of masterbatch and additive are calculated relative to batch capacity:
E.g.:
BATCH=1.0Kg, Hopper 1=AUTO calculated, 
Hopper 2=40%, Hopper 3=3%, Hopper 4=2%. Thus real weights are:
Hopper 1(raw material)=1.0 × (100%-40%-3%-2%)=0.55Kg(550g) 
Hopper 2(recycled)=1.0 × 40%=0.4Kg(400g)
Hopper 3(master batch)=1.0 × 3%=0.03Kg(30g) 
Hopper 4(additives)(=1.0 × 2%=0.02Kg(20g) 

Under this mode, weight of both master batch and additives will be adjusted automatically depending on the availability of regrind ;
 

SPECIFICATION


Note:
1) The above data is based on continuous running of even particles whose bulk densities are 0.8kg/L and diameters are 3~4mm. The values varies along material features. Please further discuss if the material is not sure;
2) The main metering valve is suitable for proportion not lower than 5% and raw material of even particles or recycled materials of even particles whose diameters are within 6×6×6mm;
3) The secondary metering valve is suitable for proportion of 0.5%~5% and master batch of even particles or additives whose diamerters are within 4×4×4mm.
4) Microscale metering valve is optional for proportioin of 0.2%~0.5% and master batch of even particles or additives whose diamerters are within 4×4×4mm;
5) Special material metering valve is suitable for sheets and irregular materials whose diameters are within 12×12×12mm;
6) Mixing and ratio deviation refers to the difference between the setting percent and actual percent of each group. The microscale metering accuracy can reach to ±0.1%;
7) Come with a set of secondary metering valves for use when replacing recipe;

APPLICATION
XGB series gravimetric blender can be used in the fields of injection moulding machines,blow moulding machines and extrusion lines for proportionally precise mixing of several type of material.This series machines adopts PLC controller and latest ingredients calculation methods;

WORKING PRINCIPLE 
 

  

When machine starts working, metering valve of storage hopper 1 opens to let material fall into gravimetric hopper according to the preset weight and time; when time is up, the valve shut down and gravimetric sensor inside gravimetric hopper responses that weight reaches the default value, then the next storage hopper metering valve opens. The material metering repeats like this until all the hoppers finish feeding. Then the gravimetric hopper shut-off valve opens to let materials fall into mixing tank to be blended. Once material in gravimetric hopper falls into mixing tank, gravimetric hopper shut-off valve shuts. Mixers keep
 

Working for a period of set time and afterwards the pneumatic slide gate will be open manually or automatically to let material falls into storage tank or injection molding machine. Until here, a complete operation circle has been finished.
