Grado Adroit – Gravimetric batch blender and extrusion control

Gravimetric batch blender, designed to blend free flowing pellets in processes which require accurate dosing and repeatability with efficient mixing. Unaffected by vibrations, GRADO ADROIT has been designed to be easily mounted directly onto the throat of the processing machine, to be installed either on a mezzanine, or on a vacuum take-off stand to feed one or more extruders.

MORE INFORMATION

SUPERIOR DESIGN COMPLYING RIGOROUS PROCESS REQUIREMENT

Full modular construction
For ingredient change, there is no need to stop and “dismantle” the machine
Practical and easy access to all parts for maintenance or quick and accurate cleaning
Drain spout for quick and complete ingredient feed hopper emptying
Clean out doors for fast removal of dust or ingredient residues and for visual inspection
Round bottom mixer can be completely emptied leaving no trace of residue material
Easy to use, simply set the dosing percentage

UNSURPASSABLE ENGINEERING AT TOP LEVEL IMPROVES RELIABILITY

Number of parts reduced at minimum
No one hand-made part, but cast aluminum, molded custom engineered plastic compounds, machined steel
PLC based control from market leader producer
Re-engineered manufacturing process reducing delivery time

IMPROVED THROUGHPUT CAPACITY IN A COMPACT SIZE

Advanced high noise immunity weighing system reduces weight measurement time
Throughput capacity results improved as per faster weighing cycle time

SUPERIOR BLENDING ACCURACY AND PRECISION

Enhanced control dynamics and weight measurement quality improves process capability

MIXING CHAMBER SIZING IMPROVES BLENDING CONSISTENCY

The 3 batches mixing chamber capacity ensure the right mixing time and improves blending consistency
As the motor mixer has a round bottom, there are no stagnation areas. The mixing paddle moves the entire mass of material resulting in a homogeneous blend and preventing the formation of preferential flows that would favor the separation of the ingredients into finer, heavier or more flowing granule sizes.
