ZS Vertical Mill Special Cement Grinding Aid

ZS Vertical Mill Special Cement Grinding Aid

1. Product Introduction

What is ZS Vertical Mill Special Cement Grinding Aid?

ZS Vertical Mill Cement Grinding Aid is a liquid functional admixture suitable for raw material vertical mills and cement final grinding vertical mills. It is formulated based on the grinding mechanism of vertical mills, taking into account drag reduction and output increase, roller wear reduction, strength improvement, and particle size distribution. Unlike traditional ball mill grinding aids, it specifically solves the pain points of vertical mills such as material sticking to the grinding disc, high pressure difference, large roller wear, and low finished product strength.

How Does It Work?

Grinding aids encapsulate clinker and mixed material particles, neutralize surface static electricity, and reduce internal friction and adhesion to the grinding disc.

Reduces grinding disc adhesion, material bed instability, and high system pressure differential, stabilizing the material bed.

Reduces roller compaction load, minimizing roller skin and liner wear.

Refines powder, optimizing the 3-32µm effective particle size range, increasing vertical mill output per hour, and reducing grinding power consumption.

Deeply activates the activity of slag and fly ash, simultaneously improving 3-day and 28-day compressive strength.

5. Frequently Asked Questions

Q: How is the optimal dosage determined?

A: Recommended dosage is 200g – 500g per ton of cement. Exact dosage depends on clinker grindability, mill type, and target fineness. Our technical team can assist with mill trials.

Q: Will adding this product affect the vertical mill's hydraulic system and lubricating oil?

A: No. The dosage is extremely low; it only adheres to the material, does not volatilize, does not contaminate the lubrication system, and is non-corrosive.

Q: Does this product contain chlorides?

A: No. Chloride content is ≤0.1%, safe for reinforced concrete.

Q: How should the product be stored?

A: It is a weakly alkaline liquid. Store in a sealed plastic container at -5℃ to 40℃.

6. Application Scope

Application	Benefit
Vertical Mill Grinding	Improved throughput, lower energy intensity
Blended Cement Production	Enables higher SCM loading while maintaining strength
Roller Press + Vertical Mill Combined System	Improved material flowability, reduced circulating load, full-line power savings

7. Usage Guidelines

Calibration: Install a dedicated metering pump and calibrate to target dosage. Addition point: clinker feed belt or mill feed hopper outlet.

Application Point: Apply evenly onto the clinker flow on the vertical mill's feed belt and feed hopper outlet.

Monitoring: Track mill amperage, production rate (t/h), and cement quality (Blaine, residue).

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