Why Can Batching Accuracy Be Stably Maintained at ±2%? Decoding the Electronic Weighing Technology of UNIK's Batching Station
In concrete block production, batching accuracy is directly related to product quality stability and production cost control. For every 1% increase in batching error, the waste of high‑cost raw materials such as cement increases correspondingly, while the fluctuation range of block strength also expands. UNIK Machinery's PL series batching station consistently maintains batching accuracy within ±2%. Behind this accuracy indicator lies a complete system of electronic weighing and intelligent control technologies working in synergy.
1. Electronic Load Cells: The Leap from Mechanical Scales to Digital Weighing
Traditional batching stations mostly use mechanical lever scales or mechanical‑electronic combined weighing systems. These not only have slow response times but are also affected by mechanical wear, temperature changes, and other factors, making it difficult to maintain accuracy over the long term. UNIK's PL series batching station fully adopts electronic load cells for weighing measurement. The sensors convert the weight of aggregates into electrical signals, which are then amplified, filtered, and converted from analog to digital before being sent to the control system. They offer fast response, strong anti‑interference capability, and excellent long‑term stability, providing the hardware foundation for achieving ±2% batching accuracy.
2. Three Models: Covering Weighing Capacities from 0.8 m³ to 1.6 m³
UNIK's PL series batching station offers three main models: PL800, PL1200, and PL1600, with weighing capacities of 0.8 m³, 1.2 m³, and 1.6 m³ respectively, and maximum load capacities ranging from 1500 kg to 4000 kg. All three models achieve ±2% batching accuracy, allowing customers to select the appropriate model based on their target production capacity (with corresponding productivity rates of 48 m³/h, 72 m³/h, and 96 m³/h respectively). In terms of hopper capacity, the PL800 is equipped with 2×2 m³ bins, the PL1200 with 3×4 m³ bins, and the PL1600 with 3×7 m³ bins, fully meeting the aggregate storage needs of production lines of various scales.
3. Intelligent Drop Compensation: Eliminating the Error of "Material in the Air"
A common source of error in the batching process is "material in the air" – when the batching station's gate closes, some aggregates are still falling. The weight of this material is not recorded by the sensors but still ends up in the mixer. UNIK's batching station control system incorporates an intelligent drop compensation algorithm. By monitoring parameters such as gate closing speed and material flow rate in real time, it automatically calculates and compensates for the weight of material in the air, ensuring that the actual weight of each material entering the mixer precisely matches the set value.
4. Modular Design: Flexible Adaptation to Different Production Line Layouts
UNIK's PL series batching station features a modular design, allowing flexible configuration of the number and arrangement of bins according to the customer's site conditions. In terms of loading height, the PL800 is 2300 mm, the PL1200 is 2500 mm, and the PL1600 is 2600 mm, accommodating different sizes of wheel loaders. Whether for a new plant or an existing line upgrade, UNIK can provide customized batching station layout solutions.
To date, UNIK's PL series batching stations have been widely used in block production lines across Southeast Asia, Africa, the Middle East, and many other countries and regions, consistently earning customer trust through stable batching accuracy and reliable operational performance. Global customers are welcome to contact UNIK Machinery for customized batching station solutions tailored to your production line requirements.
