metal chip briquette density

Ask a maintenance engineer what killed the last briquetting mould set and the answer usually points at the material. In practice, three mechanisms work together — abrasive wear, compressive fatigue, and misalignment — and the order in which they appear decides which part fails first. Quick Answer A briquetting press mould set fails through three mechanisms acting together: abrasive wear from the material being pressed, compressive and fatigue loading at the punch face and die bore, and misalignment caused by worn guide sleeves and bushes. The earliest reliable signals are falling briquette density, ejection that starts to stick or squeal, and rising press pressure for the same stroke. Key Takeaways A briquetting press mould set is a consumable system: punch, die or mould, guide sleeve or...
