The Pulverized Coal Rotor Scale is a high-precision continuous weighing and feeding device designed for fine powdered materials such as pulverized coal and fly ash. It is widely used in cement kiln precalciners, rotary kiln burners, lime kilns, metallurgical injection systems, and chemical plants. This product achieves 100% localization of all critical equipment, while its electrical control system surpasses comparable European and American products in control accuracy, response speed, and long-term stability.

All mechanical components, load cells, VFDs, controllers, and actuators are designed and manufactured in-house.
Short spare parts lead times and rapid on-site service – eliminate months of waiting for imported parts.
More competitive pricing and significantly shorter payback periods.
High-precision digital weighing module + adaptive PID regulation – dynamic control accuracy up to ±0.5%.
Response speed approximately 20% faster than comparable European/American products, quickly compensating for coal moisture and air pressure fluctuations.
Full-featured intelligent HMI in multiple languages, with one‑key calibration, fault self‑diagnostics, and historical trend logging.
Seamless integration with DCS systems via Profinet, Modbus TCP, EtherNet/IP, and other protocols.
Strong immunity to interference in high‑dust, high‑temperature, and high‑EMI environments typical of cement and lime plants.
Power consumption reduced by 15%–25% compared to traditional vane feeders + impact plate flow meters.
Precision-calculated rotor-to-housing clearance with wear‑resistant treatment – no jamming, no leakage.
Long‑term drift-free operation; monthly cumulative error ≤1%.
Extended maintenance intervals – wear part replacement time cut by more than 50%.
Long‑term strategic cooperation with major global cement groups (e.g., Conch, Huaxin, Lafarge, Holcim) and large lime producers (e.g., Omya, Trinidad).
Products exported to Southeast Asia, the Middle East, Africa, and South America.
Received formal praise and satisfaction feedback from over 100 owners – high repeat order rate.

“After more than three years of use, the scale’s zero point has barely drifted – it’s actually more stable than the previous German brand. Most importantly, if any issue arises, our domestic engineers arrive on site within two days. No more waiting for imported parts.”
— Kiln Operation Manager, a Fortune 500 cement group
“The rotor scale’s control system responds very quickly. Even when the kiln hood pressure fluctuates, the coal feed rate remains almost unaffected. We have converted multiple production lines to this supplier.”
— VP of Production, a major lime company
“The energy saving is obvious. At the same output, our power meter shows nearly 20% less consumption, and the HMI is far more user‑friendly than the European one.”
— Plant Manager, a cement plant in Central Asia
On‑site commissioning and operator training
Long‑term spare parts supply (dispatch within 24 hours)
Remote technical support and predictive maintenance guidance
Retrofit and upgrade of existing scales (drop‑in replacement for imported brands)
