1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing grinding circuit bottlenecks that limit your plant’s throughput? Unplanned downtime for mill liner changes and mechanical failures directly erodes profitability, with stoppages costing thousands per hour in lost production. Inconsistent grind size and product quality can lead to downstream processing inefficiencies and noncompliance with product specifications. Rising energy consumption per ton of processed material remains a primary operational cost driver. En outre, navigating complex international markets requires not just performance, but guaranteed compliance.

How do you select a ball mill that delivers consistent operational reliability, minimise le coût total de possession, and provides the certified documentation required for seamless deployment across Europe and other regulated markets? The solution requires machinery engineered for performance and backed by unambiguous regulatory certification.

2. APERÇU DU PRODUIT

This product line comprises a range of CE Marked Ball Mills, engineered for continuous or batch grinding operations in mineral processing, production de ciment, and industrial minerals sectors. These rotating cylindrical shells use steel grinding media to reduce material particle size through impact and attrition.

Flux de travail opérationnel:
1. Présentation du flux: Crushed ore or raw material is fed into the mill via a sealed inlet trunnion.
2. Action de broyage: Le moulin tourne, lifting the charge of steel balls which cascade and tumble, fracturing the material.
3. Classification & Décharge: Ground material is discharged through an outlet grate; la taille des particules est souvent contrôlée en circuit fermé avec un classificateur externe (par ex., cyclone).

Champ d'application: Ideal for wet or dry grinding of abrasive and hard materials in mining, carrière, and chemical industries.
Limites: Ne convient pas au broyage ultrafin en dessous de ~20 microns sans conception de circuit spécialisée; physical footprint and foundation requirements must be assessed during plant design.
