Product Description

Large-capacity 3-point zero-gravity feeder
Zero-gravity scale, also known as zero-gravity feeder or loss-in-weight scale, is a weighing device that employs intermittent feeding and continuous discharging. It is mainly used for precise batching control of powdered and granular materials in industries such as cement, coal powder, chemical engineering, and food processing. Its core working principle is based on the combination of static weighing and dynamic PID control. By real-time monitoring the weight change rate of the material in the hopper, it adjusts the speed of the screw feeder or electric vibrating feeder to achieve accurate metering within a flow range of 0.01-300 t/h, with a system error ≤0.5%.
The equipment consists of a sealed hopper, feeder, load cells, and control system, adopting a modular design that supports quick assembly and disassembly. Two sets of PID algorithms perform coarse adjustment and fine adjustment of the flow rate respectively, and are accompanied by a make-up feeding mechanism to ensure continuous feeding, effectively solving problems such as material bridging. It features pressure resistance, explosion-proof capability, online calibration function, and is suitable for dusty environments. Through software support, it can achieve multi-scale coordination, formula storage, and remote communication, meeting the needs of industrial automated production.
Specification
Applications
System measurement accuracy ≤ 0.5%
System batching accuracy ≤ 0.5%
Batching measurement control range: 0.01-300 t/h
Application scope: Continuous stabilized soil, concrete mixing station cement batching, sintering quantitative control feeding, coal powder quantitative control feeding, and batching of various thick slurries, etc.
Product introduction of loss-in-weight feeder: Also known as loss-in-weight feeder, loss-in-weight feeder, and loss-in-weight batching scale.
The loss-in-weight feeder consists of a hopper, feeder (single or double screw feeder), weighing system, and regulator. During operation, the hopper, material, and feeder continuously weigh together. After the material is discharged, the actual loss-in-weight rate is measured and compared with the required loss-in-weight rate (set value). The feeder rate is automatically adjusted to correct the deviation from the set point, thereby enabling uniform and accurate continuous feeding of materials.
Suitable scope: Granules, powders, calcium carbonate, talcum powder, resin film powder products, flour, starch, etc.
Powder scale: Solves the feeding and metering addition problems of materials with very poor fluidity;
Granule scale: Solves any possible bridging problems.
