Case Study: Tackling Fly Ash Treatment for a Major Cement Plant

2025-09-19

Project Background

During cement manufacturing, the generation of fly ash is a significant operational challenge. For a major cement producer, the high water content and fine particles in their fly ash slurry made traditional solid-liquid separation inefficient. The environmental company servicing this client turned to us for an advanced dewatering solution that could meet stringent environmental regulations while lowering disposal costs.

Customer Challenges

High moisture content in fly ash (over 85%), difficult to handle and transport
Fine particle size requiring high-efficiency separation technology
Large processing volume demanding continuous, stable operation
Strict environmental discharge standards for water quality
Need to minimize operational and maintenance costs
Limited space for equipment installation in existing facilities

ZK SEPARATION Solution

Based on the specific requirements of fly ash treatment in cement production, we recommended the LW580 X 2400B two-phase decanter centrifuge with thin oil lubrication system. This equipment is specifically designed for handling fine particles and high-volume continuous operation in industrial applications.
