Démystifier 15-20 Concasseur De Pierre De Tonnes: Powerhouse Solutions for Medium-Scale Aggregates

The quest for reliable, efficient aggregate production often leads to the versatile segment of 15-20 ton stone crushers. Occupying a crucial middle ground, these machines deliver substantial crushing power while maintaining maneuverability and operational flexibility. Understanding their capabilities, candidatures, and key considerations is vital for selecting the right workhorse for demanding medium-scale projects.

Capacités de base: Striking the Balance

Machines in this weight class are engineered to handle significant volumes of hard rock, calcaire, granit, basalte, et béton recyclé. Their defining characteristics include:

1. Robust Output: Expect production capacities typically ranging from 80 à 180 tonnes par heure (TPH), depending heavily on:
Feed Material Hardness & Taille: Harder rocks and larger feed sizes reduce throughput.
Desired Final Product Size: Finer grading requires more crushing stages or closed-circuit screening, impacting overall rate.
Type de concasseur & Configuration: Jaw crushers excel on primary hard rock; cone crushers are ideal for secondary crushing to finer sizes; impact crushers suit softer materials and shaping applications.

2. Significant Power: Driven by diesel engines or electric motors usually ranging from 55 kW (75 HP) jusqu'à 132 kW (180 HP) ou plus. This power translates into the force needed to fracture tough materials consistently.

3. Flexibilité opérationnelle:
Mobile Versions (Dominant): Most modern 15-20T crushers are mobile units – either tracked or wheeled. Tracked crushers offer superior mobility on rough terrain directly at the face or within demolition sites. Wheeled options are often faster to relocate on roads between sites.

Semi-Mobile/Skid-Mounted: Offer a stable platform with easier setup than fixed plants but less mobility than full-tracked units.
Encombrement compact: Designed to work effectively in constrained spaces common in quarries, chantiers de construction, and recycling yards.

Applications principales: Where They Shine

This capacity range makes 15-20 ton crushers exceptionally well-suited for:

1. Medium-Sized Quarrying Operations: Serving as primary or secondary crushers in pits producing aggregates for local construction markets.
2. Projets d'infrastructures: Crushing material directly on-site for road base, sous-base, ballast ferroviaire
