YB-WSZ Micro Loss-in-weight Feeder

The YB-WSZ micro-quantity twin-screw loss-in-weight feeder is a continuous quantitative feeding device specifically developed for small-flow materials based on the twin-screw loss-in-weight feeder. It features lighter overall weight, smaller structure, and more flexible installation. Utilizing small-range weighing sensors, it is more sensitive to material weight, facilitating precise feeding and improving production efficiency.

Product features include self-cleaning twin screws, high corrosion resistance and IP protection rating, automatic dual-speed switching gearbox, lean-designed dual-arch-breaking mechanism, stainless steel clamp structure, and a dedicated microchip controller for loss-in-weight feeders. Its dynamic measuring accuracy ranges from 0.2% to 0.5%.

Suitable for sticky, blocky, free-flowing, and difficult-to-handle powder materials, the YB-WSZ micro-quantity twin-screw loss-in-weight feeder plays a crucial role in the production batching process.

High Precision Weighing:

Independently developed microchip controller, fully digital weighing technology, industry-proven overall structural design, and dual closed-loop PID regulation achieve higher precision feeding technology, with static accuracy better than 0.1%; linear, repeatability dynamic accuracy better than 0.3%.

Excellent Control Technology:

Controlled by a dedicated microchip for loss-in-weight scales, it offers more advantages compared to ordinary PLCs, with high-speed computation, quick response, stable operation, achieving higher feeding accuracy and stability. It features 2 communication interfaces for data exchange with touch screens, industrial PCs, etc.

High Corrosion Resistance and IP Protection Rating:

All parts in contact with materials are made of 304 stainless steel, with an appearance treated by electrolytic polishing process, combining aesthetics and stability. Even in harsh environments, it is durable and suitable for industries such as pharmaceuticals, food, and chemicals that demand cleanliness and corrosion resistance.

Dual Arch Breaking Mechanism:

Featuring a specially designed spherical hopper structure, for high viscosity, high specific gravity materials, a dual arch breaking mechanism is employed: vertical arch breaking agitator + horizontal mixing device, ensuring smooth discharge of any material while fully ensuring the stability of feeding accuracy.


Principle:

The loss-in-weight scale weighs the measuring hopper and the entire feeding mechanism as one unit. As material flows out of the loss-in-weight scale, the control system rapidly and frequently collects weight signals from the scale body, calculates the weight reduction of the material in the measuring hopper per unit time, and determines the actual flow rate of the loss-in-weight scale through unique filtering and optimization processes. Simultaneously, the control system compares this feeding speed with the preset feeding speed, and feeds the comparison result back to the feeding mechanism of the loss-in-weight scale to automatically adjust the feeding speed, forming a closed-loop control, thereby making the actual flow rate infinitely approach the desired flow rate to meet control requirements.
