Our customer, Sackers Scrap Metal & Waste Recycling, wanted to know which grade would last the longest in their application: metal recycling shredder liners.
They ordered a set of liners in 400HB and Creusabro® 8000 to do a comparison.
The 400HB liners lasted just 2 months whilst the Creusabro® 8000 liners lasted 4 to 5 months giving 100 – 150% extra wear life when compared to 400HB.
Not only does the C8000 work out cheaper when we compare the £’s per hour of the parts but it also reduces the amount of plant downtime for changing parts.
Abraservice UK were asked to give advice on upgrading chutes at one of Hanson’s cement plants. The customer was having issues with existing liner plates breaking (chrome carbide overlay plate) or falling off (ceramic) due to impact. They were looking for a solution to eradicate the need for constant maintenance and expensive clean-up costs from the excessive amounts of dust leaking from the chutes.
We recommended using CREUSABRO® 8000 to replace the damaged liners and backing plates based on its unique concept. The CREUSABRO® grades strongly improve their wear resistance in service by surface hardening up to +70 HB (known as the TRIP-effect). The soft quenching rates produce a uniform through-hardened plate with lower levels of residual stress resulting in higher levels of crack resistance. The grades are also suitable for continuous use at higher operating temperatures; the specific chemical composition and microstructure make the material more resistant to softening. Cement plants are well known for having issues caused by impact, abrasion (wet or dry), and high temperatures which made CREUSABRO® 8000 the perfect choice.
On approval of the material we went back to site to do a full scope of work which included measuring up 11 different chutes for new liners and backing plates where needed and making suggestions of improvements to chutes with other issues (flow / damage). We provided detailed layouts for fitting on site by contractors and created a full parts library for ease of ordering spares.

We would like to thank Hanson Cement for the opportunity and work, we look forward to working with you again in future.
