Powder vacuum weighing systems are capable of handling the storage, conveying, weighing and batching, dust removal, and mixing of various raw materials, including powders, granules, lumps, flakes, and more. Depending on material characteristics, feeding methods such as belts, screws, discs, or regulating valves can be employed, combined with control technologies like frequency converters and servos. This enables batching accuracy up to one-thousandth, ensuring precise adherence to customer formulations.

The weighing system utilizes the following measurement methods:

Loss-in-Weight (Reduction Method), mainly suitable for:

Processes requiring high precision in batch batching;

Requirements for continuous and uniform quantitative feeding;

Situations where installation constraints make the gain-in-weight method inconvenient.

Gain-in-Weight Method, mainly suitable for:

Processes with relatively lower precision requirements in batch batching;

Situations where installation constraints make the loss-in-weight method inconvenient.

Powder vacuum weighing systems offer numerous features, including flexible setting of multiple formulation weight values, user-friendly and intuitive operation, and free ratio mixing of various materials, supporting formulations with up to ten or more ingredients.

Feeding and weighing processes are continuous, without interruptions, and highly efficient.

The entire process adopts a sealed structure, with an automatic dust collection system for dust removal, ensuring a clean and pollution-free on-site environment.

Multiple material formulations can be pre-programmed and stored, offering flexibility, reliability, and convenience.

Depending on material characteristics, feeding methods such as belts, screws, or vibration can be selected, complemented by frequency modulation devices and high-precision flow control valves to effectively regulate material flow and ensure batching accuracy.

Signal protection or shielding devices can be included to prevent interference from industrial control signals.

The system can be configured with various anti-bridging devices such as air pads, agitators, or vibrators to prevent material segregation or separation.

Safety: The entire system can be controlled and operated using only compressed air, without the need for electrical or mechanical energy. No heat is generated during operation, ensuring safety and explosion-proof performance. Effectively eliminates static electricity in materials and causes no pollution to the surrounding environment.

Simplicity: Automated control allows the suction and discharge times to be set flexibly within 0–30 seconds. Operation is simple and convenient.

Hygiene: Enclosed conveying prevents dust leakage and cross-contamination, complying with GMP standards and meeting CIP requirements. Capable of providing sterile-grade products.

Lightweight: Compact size, lightweight design, and simple, quick installation.

Quiet Operation: No vibrations and low noise levels.

Cleanliness: Dust-free operation with modular design, eliminating dead corners. Quick and easy disassembly, cleaning, and material changeover.

Efficiency: Conveying capacity can reach up to 6 tons per hour, with horizontal conveying distances up to 50 meters and vertical distances up to 30 meters, effectively addressing the issue of material segregation.

Economy: A single machine can be used in rotation across multiple setups. Energy-efficient, with no warm-up or standby requirements, resulting in low operational and maintenance costs.
