Old Craftsman carbide crusher hammers improve mining efficiency primarily by significantly extending the service life of the crushing equipment, which leads to less downtime, lower maintenance costs, and more consistent crushing performance. Our tungsten carbide crusher hammers combine a tough steel hammer body with highly wear-resistant carbide working surfaces, helping mining operations achieve longer service life and more stable crushing performance.
1. Exceptional Wear Resistance
Tungsten carbide provides extremely high hardness and excellent resistance to abrasive wear. This makes carbide crusher hammers particularly suitable for hard and abrasive materials such as granite, basalt, quartzite, limestone, ores, and aggregates.
Compared with conventional hammer materials, carbide can better maintain the working surface during continuous crushing, reducing the rate of material loss.
2. Longer Crusher Hammer Service Life
Frequent hammer replacement can interrupt production and increase spare-parts consumption. Old Craftsman carbide crusher hammers are designed to provide substantially longer wear life, depending on the crusher, feed material, impact conditions, and carbide grade.
Field research on tungsten-carbide hardfaced hammer heads has also demonstrated significant service-life improvements compared with conventional steel hammer heads.
3. More Consistent Crushing Performance
As ordinary hammers wear, their working profiles gradually change, which can affect crushing efficiency and product size consistency. Carbide maintains its wear-resistant profile for longer, helping the hammer continue delivering stable crushing performance.
This is especially valuable when consistent particle size is important for downstream screening, grinding, or mineral-processing operations.
4. Reduced Maintenance Downtime
Longer wear life means fewer planned and unplanned hammer changes. For continuous mining operations, this can translate into:
- Fewer crusher shutdowns
- Lower replacement frequency
- Reduced maintenance labor
- Less spare-parts consumption
- Higher equipment availability
Vacuum brazing can further improve the reliability of carbide-to-steel connections by creating a strong metallurgical bond between the carbide inserts and steel hammer body.
5. Better Balance Between Wear Resistance and Impact Toughness
Crusher hammers need more than hardness—they must also withstand repeated impact. Old Craftsman can select carbide grades and hammer structures according to the specific operating conditions.
For example, carbide grades such as YG8 and YG15 can be considered for different combinations of impact and abrasion requirements. The optimum grade should be determined according to feed material, crusher type, rotor speed, feed size, and actual wear conditions.
6. Lower Total Operating Cost
Although carbide crusher hammers may have a higher initial purchase price than conventional hammers, the real value comes from total cost of ownership.
A longer-lasting hammer can reduce replacement parts, maintenance labor, downtime, and production interruptions. Therefore, carbide can provide a more economical solution for high-abrasion mining applications over the complete operating cycle.
