Gravimetric feeder

industrial

Overview
A gravimetric system in pneumatic conveying systems is an advanced technology designed to measure and control the flow of bulk materials in pneumatic transport systems. This system uses sensors and weighing devices to accurately monitor the amount of material being transported, ensuring that dosing specifications are met. Gravimetric systems are crucial for applications requiring precise control of material quantities, enhancing process efficiency and ensuring the quality of the final product.

Features

• Gravimetric in Stainless Steel / Carbon Steel.
• Upper system with 2 compartments for feeding 2 raw materials (PVC compound and calcium carbonate).
• Dynamic double-length mixing system with motor reducer at 180°.
• Control panel with Siemens PLC, 7" color touchscreen HMI Siemens, and electrical protections at 220-440VAC/60Hz/3Ph.
• Possibility of communication with client’s supervision software.
• Traceability of extruder machine consumption.
• Frequency inverters for motors.
• High-impact beater for static mixer.
• Field terminal block housing.
• Bottom connection to the hopper on the extruder machine.
• Easy-to-install monoblock equipment.
• Top connection to the hopper.
• Capacity between 30-50 PHR of calcium carbonate (according to requirements).

Types

• In-Line Weighing Systems: Directly integrated into the transport line, allowing real-time measurement of material flow during pneumatic transport.
• Batch Dosing Systems: Designed to measure and control specific quantities of material in each batch, providing precision in loading and unloading.
• Continuous Flow Control Systems: Continuously monitor and adjust material flow to maintain a steady rate and avoid process interruptions.
