ZS-High-Efficiency Enhanced Cement Grinding Aid

ZS-High-Efficiency Enhanced Cement Grinding Aid

1. Product Introduction

What is ZS-High-Efficiency Enhanced Cement Grinding Aid?

ZS-High-Efficiency Enhanced Cement Grinding Aid is a high-performance product that combines powerful grinding assistance with superior strength enhancement. It is formulated for Portland cement, ordinary Portland cement, composite Portland cement, fly ash Portland cement, pozzolanic Portland cement, slag Portland cement, and masonry cement. This product aims to improve grinding efficiency, increase mill output, enhance cement strength, and improve the mechanical properties of the final cement product.

How Does It Work?

Particle Dispersion: Neutralizes static charges on cement particle surfaces during grinding, preventing agglomeration and reducing the "cushioning effect" inside the mill.

Grinding Efficiency: By keeping particles separated, it allows the grinding media to work directly on the clinker, reducing energy consumption per ton.

Strength Activation: The active components chemically interact with cement phases (C₃S, C₂S), promoting more complete hydration and contributing to both early and late strength development.

5. Frequently Asked Questions

Q: What types of cement is this product suitable for?

A: It is suitable for Portland cement, ordinary Portland cement, composite Portland cement, slag cement, pozzolanic cement, fly ash cement, and masonry cement. For specialized types such as oil well cement, please contact our technical team for custom formulations.

Q: How is the optimal dosage determined?

A: The recommended range is 250g – 1000g per ton of cement. Exact dosage depends on clinker grindability, mill type, target fineness, and SCM content. Our team can assist with industrial trials to find your economic optimum.

Q: Does Shengchuan have real case studies for this product?

A: Yes. In a Guangxi P·O 42.5 plant, clinker usage dropped from 86.6% to 80.0% while maintaining 28-day strength. In another Guangxi P.C 32.5 plant, SCM usage increased from 29.5% to 34.7%, and both early and late strength improved.

Q: What is the difference between this and the General-Purpose series?

A: The High-Efficiency Enhanced series features a dual-action formula combining powerful grinding assistance with superior strength activation. It contains enhanced active components, ideal for plants requiring maximum strength improvement or aggressive clinker reduction.

Q: How should the product be stored?

A: It is a weakly alkaline liquid. Store in a sealed plastic container at temperatures between -5℃ and 40℃. Shelf life: 12 months.

Q: What are the main components?

A: The product is mainly composed of alcohol amines, polymeric polyols, and sugars, with a small amount of inorganic salts. It is generally light yellow, odorless, and does not harm human health or cement concrete properties.

6. Application Scope

Application	Benefit
Ball Mill / Vertical Mill Grinding	Lubrication and drag reduction, increased production and reduced consumption
Blended Cement Production	Enables higher SCM loading while maintaining strength targets
High-Volume Limestone Cement	Enhanced particle size distribution for improved workability

7. Usage Guidelines

Calibration: Install a dedicated metering pump and calibrate it according to the target dosage. Direct metering can be used when no lift is required; otherwise, a two-stage pumping method is recommended. The addition point should be on the clinker feed belt or at the mill inlet.

Application Point: Apply the grinding aid evenly onto the clinker feed before entering the mill to ensure uniform dispersion.

Monitoring: Track mill amperage, production rate (t/h), cement quality (Blaine, residue), and critically, 28-day compressive strength to quantify performance improvement.

Note: We provide customers with methods for detecting and controlling the feed rate.
