Gravimetric Blender
Application
It is mainly used for handling 2 to 12 different components by dosing and blending in total throughput from 35kg/hr to 1000kgs/hr; including virgin, regrind materials, masterbatch and other various additives. This series adapts high precision load sensors to make batch blend resulting in a highly accuracy within±0.5%( accurate tolerances are varied according to batch to batch blend ratio ). Full wide range of this series can satisfy versatile requirements on high precision blending.
Feature
• The ratio or percentage of materials can be set for simple and convenient operation;
• The next batch is weighed while blending;
• Adopting advanced batching algorithm, self-optimization, automatic adjustment compensation and vibration prevention function to ensure the best batching accuracy;
• Modular removable structure design, saving space and convenient cleaning;
• Handle up to five kinds of materials at the same time;
• Color chart display, touch screen operation interface;
• It has the function of recipe storage and can up to 20 recipes can be stored for later use;
• Multilevel password protection and historical alarm record;
• USB interface for saving recipe data to flash disk, automatically recording the proportion and weight of each batch;
• With sound and light alarms to facilitate operators to quickly and accurately reach the scene of failure machines;
• All parts in contact with the material are made of stainless steel to prevent contamination of the material;
• Can be installed directly on the machine or the optional foot frame is installed next to the machine;

Note:
1) The mixing ratio error refers to the difference between the set percentage and the actual percentage of each component;
- The knife metering valve is suitable for the ratio of 5% or more, and the mixing ratio error can be controlled within ±0.3-0.5%;
- (screw or) micrometer is suitable for the ratio of 5% (excluding) to 0.5%, the mixing ratio error can be controlled at ± 0.2%;
- The above max processing amount and mixed ratio error data are measured by continuous operation of the uniform material of the bulk density of 0.7kg/L and diameter of 3-4mm. The max output will vary according to the amount and proportion of the measured components.
- The machine voltage specification is: GDK-5 and below models: 1Φ230VAC, 50Hz; GDK-10 and above models: 3Φ380VAC, 50Hz
Options
• Floor stand, pneumatic slide gate, storage bin and suction box should be optionally purchased for floor mounting.
• Ethernet interface, MODBUS, PROFIBUS communication module, which can realize remote monitoring, or with extruder, injection molding machine to transfer data.
