High-precision Gear Pump For Cement Grinding Aids

This gear metering pump is custom-engineered for the precise dosing of liquid grinding aids in cement plants. As a precision positive-displacement pump, it is suitable for handling various types of retarding and composite cement grinding aids and admixtures. The pump body is available in 304/316 stainless steel or corrosion-resistant composite materials to handle mildly corrosive, medium-viscosity media, ensuring stable, pulsation-free flow.

It offers high metering repeatability, with flow rates linearly adjusted via variable frequency drive (VFD). It integrates with DCS automation systems to synchronize dosing with mill output, ensuring consistent cement quality and minimizing grinding aid waste. Featuring a robust, durable design, the pump withstands the harsh, dusty, and high-temperature environments of cement plants and is easy to maintain. Options include mechanical seals or leak-free magnetic drive seals, with customizable displacement and mounting interfaces, making it widely used in automated grinding aid dosing systems at cement grinding stations.

Advantages

Precise metering, uniform dosing, reduce grinding‑aid consumption

Wear‑resistant, reliable for dusty cement plant environment

Variable speed control, compatible with automatic DCS system

Multiple anti‑corrosion material options for different additives

Simple structure, low maintenance, long‑time continuous operation

FAQ

1. Q: Can the flow rate be automatically adjusted to match the mill's output?
A: Yes; the pump can be equipped with a variable frequency drive (VFD) or servo motor and integrated with a 4–20mA signal to enable fully automatic, demand-based feeding.
2. Q: Will minor sedimentation in the grinding aid damage the pump?
A: The gear-based design is resistant to minor impurities; using an upstream filter yields even better results, making it well-suited for cement plant operating conditions.
3. Q: Can the pump achieve zero leakage?
A: Yes; it can be upgraded to a magnetic drive configuration, completely eliminating the risk of additive drips or leaks contaminating the site.
