1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing persistent bottlenecks in your size reduction process? Distribution granulométrique incohérente, coûts excessifs de remplacement des pièces d’usure, and unplanned downtime for maintenance are not just operational nuisances—they directly erode your profit margins. When your hammer mill struggles with feed variability or requires frequent screen changes and rotor servicing, your entire production line suffers. The resulting costs are quantifiable: lost throughput during changeovers, rising energy consumption per ton processed, and labor hours spent on reactive repairs instead of proactive operations.

Ask yourself: Is your current comminution equipment causing unpredictable product quality? Are your operational expenses for wear parts exceeding budget forecasts? How much production capacity is lost annually to maintenance cycles? Un robuste, wellengineered hammer mill is not merely a piece of machinery; it is the core of your material preparation circuit, and its performance dictates your plant’s efficiency.

2. APERÇU DU PRODUIT

The industrial hammer mill is a highimpact size reduction crusher designed to transform coarse raw materials into a predetermined, consistent granular or fine product through repetitive hammer blows. Its operational workflow is a continuous, highspeed process:

1. Consommation alimentaire: Bulk material is gravityfed or conveyed into the grinding chamber via a controlled feed mechanism.
2. Réduction de taille: Centrifugal force swings hardened hammers outward, shattering material upon impact against the liner plates and forcing it through a perforated screen.
3. Classification des particules: The screen acts as a sizing gauge; particles small enough pass through, while oversized fragments are retained for further reduction.
4. Décharge: Sized material exits the chamber, généralement par gravité ou système pneumatique, pour le traitement en aval.

This equipment is highly effective for intermediate crushing and fine grinding of mediumhard to soft materials (par ex., calcaire, charbon, agrégats, certains minéraux). Its primary limitation is suitability for highly abrasive or very hard (>Mohs 7) materials without incurring prohibitive wear costs.

6. SCÉNARIOS D'APPLICATION

Production globale & Limestone Quarrying Challenge A midsized quarry faced inconsistent product gradation for their agricultural lime products and high weekly downtime for hammer rotation/replacement due to abrasive silica content.

Solution Implementation of a heavyduty hammer mill featuring reversible HiCr hammers and an adjustable grinding screen system tailored for their specific feed stock.
Results Achieved a consistent minus10mm product with >95% fiabilité. Wear part service intervals extended from weekly to biweekly cycles, increasing annual crusher availability by an estimated 18%.

Mineral Processing PreConcentration Challenge A mineral sands operation needed to liberate valuable minerals from softer gangue material ahead of concentration but found their existing crusher created excessive fines (100 engrener), leading to losses in downstream recovery circuits.

Solution A centerfeed hammer mill configured with larger screen apertures and lower peripheral tip speed was integrated into the circuit.
Results Effective liberation was achieved while reducing the generation of problematic fines by over 30%. This improved overall recovery rates in the subsequent gravity separation stage.
