Cement & Aggregates - Cement mixer - Bottom scrapers - Stationary equipment - Belgium - +43% lifetime

Objective

Assess the performance of Creusabro^® 4800 as a replacement for 400 HB water-quenched steel in the bottom scrapers of a cement mixer, with the aim of extending wear life and reducing maintenance downtime in a high-friction, rotating environment.

Test Conditions

• Location: Cement plant in Belgium

• Environment: Constant abrasive contact with raw mix material inside the cement mixer. The scrapers are subject to frictional wear from continuous scraping against both material and drum surface.

• Function: Bottom scrapers ensuring proper flow, mixing and cleaning inside the drum.

• Original material: 400 HB water-quenched steel

• Replacement material: Creusabro® 4800, processed by plasma cutting and drilling.

Results

• The 400 HB steel scrapers achieved a wear life of 200 operating hours before requiring replacement.

• The Creusabro® 4800 scrapers extended service life to 290 hours, representing a +43% improvement in durability under identical working conditions.

• The plates were cut and drilled using standard methods, allowing for easy integration into the existing system.

Value Delivered

• Longer Wear Life: +43% improvement reduced scraper replacement frequency and unplanned maintenance.

• Greater Equipment Availability: Extended scraper lifetime meant fewer production stops and improved process continuity.

• Cost Savings: Less frequent part replacement resulted in reduced maintenance and spare part costs.

• Easy Fabrication & Fitment: Processing with plasma cutting and drilling ensured a smooth and efficient installation.

Conclusion

By upgrading to Creusabro® 4800, Douterloigne and Abraservice implemented a durable and cost-efficient solution for cement mixer scrapers — achieving a 43% gain in service life, reduced downtime, and better operational efficiency.

Creusabro® 4800 confirms its value in the abrasive, high-friction conditions of cement mixing applications, where reliability and resistance are key.
