In the batching process for monolithic refractories, long-standing issues such as bridging and blockages of powders, significant metering errors, excessive dust, and inefficient product changeovers have plagued operations. These problems not only affect product stability but also drive up production costs and constrain capacity. Sihyde’s automated batching line with 30 bins for monolithic refractories directly addresses these industry pain points, offering a fully automated, end-to-end solution that provides reliable support for refractory companies seeking to improve quality, enhance efficiency, and stabilize production.
I. Arch Breaking and Blockage Prevention: Avoiding Material Interruptions and Downtime
In traditional batching lines, powders are prone to bridging, and aggregates often flow poorly, leading to frequent stoppages for cleaning.
l Sihyde employs a composite arch breaking and blockage prevention technology, combining pneumatic jetting and mechanical vibration in a dual-action mechanism. High-frequency vibration in aggregate bins forces material flow, while powder bins are equipped with WAM level monitoring and air-pad flow aids.
l Coordinated storage across 30 bins, paired with air cannon cleaning devices, accommodates materials of varying densities, such as high-alumina aggregates and silica fume. For ultra-fine materials, a disk feeder resolves floating issues, ensuring continuous material supply from the outset.

II. High-Precision Metering with 0.5% Accuracy: Ensuring Consistent Formulation
Inaccurate batching ratios directly cause fluctuations in product performance.
This production line utilizes two-stage speed regulation with closed-loop feedback. A screw conveyor handles rough dosing, while a vibratory feeder precisely adjusts the flow rate. This is coupled with 0.5%-accuracy compression load cells and a Siemens PLC for real-time control. Pneumatic valves provide precise material cut-off, achieving a dynamic error of ≤ ±0.5%. This ensures high consistency across multiple batches, effectively reducing the rejection rate.
III. Fully Enclosed Dust Suppression: Ensuring Environmental Compliance and a Better Workspace
Heavy dust in refractory workshops and increasing pressure to meet environmental standards are common industry challenges.
l Sihyde has developed a fully enclosed dust suppression system, where bins, conveyors, and mixers are sealed throughout the process.
l This is complemented by a centralized pulse-jet dust collection system, with galvanized ductwork directing dust extraction at key points. From material feeding to packaging, there is no significant dust escape, meeting environmental requirements while significantly improving the working environment.
IV. Intelligent Palletizing: Tangible Cost Reduction and Efficiency Gains
In production scenarios featuring multiple varieties and small batch sizes, challenges such as slow recipe changeovers, high labor dependence, and inefficient palletizing are prominent.
l The production line is built around a Siemens PLC central control system, enabling one-click recipe switching and full production traceability, reducing manual intervention by 30%.
l At the backend, it integrates full-stack robotic palletizing. For 25kg bags, it automates edge folding, sewing, and intelligent stacking with deviation correction, boosting overall efficiency by 60%. This achieves an unmanned, end-to-end process from batching to palletizing.
Conclusion
Sihyde’s automated batching line with 30 bins for monolithic refractories integrates five core advantages: arch breaking and blockage prevention, high-precision metering, enclosed dust suppression, intelligent scheduling, and robotic palletizing. It provides a one-stop solution to the chronic industry problems of blockages, inaccuracy, dust, and slow changeovers, stabilizing quality, enhancing efficiency, and empowering enterprises in their journey toward automated upgrading for monolithic refractory production.
