1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing grinding operations where contamination, inconsistent output, and high operational costs are eroding your margins? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the true cost of a ball mill extends far beyond its initial purchase price. Tenez compte de ces défis opérationnels courants:
Contamination matérielle: Noncompliant grinding media or liners can introduce restricted substances (comme du plomb, cadmium, mercure) into your product batch, leading to costly rejections, especially for electronics, médicaments, or highpurity ceramics.
Mouture incohérente & Rendement: Variable feed size or worn components cause fluctuations in final particle size distribution. This reduces downstream process efficiency and product quality, ayant un impact direct sur vos résultats.
Consommation d'énergie excessive: An inefficient drive system or poorly designed chamber can lead to energy waste constituting up to 4050% of your milling operational costs.
Temps d'arrêt imprévus: Frequent maintenance stops for liner replacement or bearing failures disrupt production schedules, creating bottlenecks and delaying order fulfillment.
Coût total de possession (Coût total de possession) Creep: Hidden costs from short component lifespan, high energy draw, and potential compliance fines accumulate silently.

How do you specify equipment that ensures product purity guarantees reliable throughput and provides a predictable operational expense? The solution lies in precision engineering focused on compliance and efficiency from the ground up.

2. APERÇU DU PRODUIT

This product line encompasses a series of industrialgrade RoHS Compliant Ball Mills engineered for consistent, contaminantfree size reduction. These mills are designed for wet or dry grinding of ores, minéraux, produits chimiques, and other materials where strict control over heavy metal introduction is paramount.

Flux de travail opérationnel:
1. Alimentation contrôlée: Raw material is fed into the rotating cylindrical chamber containing RoHScompliant grinding media.
2. Impact & Usure: As the chamber rotates, the tumbling media crushes and grinds the material through impact and friction.
3. Particle Size Refinement: The ground material is continuously reduced until it reaches the target fineness, determined by residence time and mill dynamics.
4. Décharge & Classification: The processed slurry or powder is discharged through a grate system for further classification or direct use in the next production stage.

Champ d'application: Ideal for mineral processing pilot plants, advanced ceramic powder production, specialty chemical manufacturing, and electronic material preparation. Non conçu pour le concassage primaire de grosses matières premières (>25mm) or for processing highly explosive materials without specialized modification.
