1. Addressing Core Operational Challenges in Aggregate Production
Managing a sand and gravel operation requires balancing relentless production demands with stringent control over profitability. Industry data indicates that unplanned downtime and inconsistent product quality are primary drivers of eroded margins. Are you facing these specific challenges?
Kostot e larta të pjesëve të veshjes & Ndalesa të paplanifikuara: Abrasive silica and aggregate materials degrade equipment rapidly. Frequent component failure on primary crushers or screens leads to production halts, kushton mesatarisht $1,800 per hour in lost output and emergency maintenance.
Inefficient Material Classification: Inaccurate sizing from underperforming screening equipment results in product contamination. This leads to load rejections, premium product being downgraded, and an inability to meet tight specifications for concrete or asphalt mixes.
Gjenerimi i gjobave të tepërta & Yield Loss: Improper crushing chamber geometry or excessive crusher speed creates more fine material than marketable product, directly reducing the yield of highvalue coarse aggregates.
Konsumi i lartë i energjisë për ton: Older, nonoptimized crushing circuits can consume 3040% more power per ton of processed material, making energy a topthree operational expense.
Rigid Plant Layout & Scalability Limits: Fixed conveyor systems and stationary primary units complicate site progression and make it difficult to economically process satellite deposits, limiting reserve life.

2. Pasqyrë e produktit: HighCapacity Mobile Cone Crusher Plant
This solution is a trackmounted, closedcircuit cone crusher and screening plant designed for secondary and tertiary crushing in sand and gravel applications. It processes feed material from a primary crusher into precisely sized aggregates.
Rrjedha e punës operative:
1. Pranimi i furnizimit: Sized feed (në mënyrë tipike 5" / 125mm) from a primary jaw crusher is delivered via excavator or wheel loader into the integrated feed hopper.
2. ClosedCircuit Crushing & Përmasat: Material is crushed in the highperformance cone crusher chamber. The entire output is conveyed to an onboard sizing screen.
3. Product Separation: The tripledeck screen separates output into multiple specification products (p.sh., ¾" çip, concrete sand, shkëmb kullues).
4. Riqarkullimi & Grumbullimi i rezervave: Oversize material is automatically recirculated back to the crusher inlet (closedcircuit operation). Onspec material is conveyed to designated stockpiles via radial conveyors.
Fusha e Aplikimit & Kufizimet:
Fushëveprimi: Ideal for producing spec aggregates for road base, konkrete, asfalt, and drainage applications. Excels in processing hard, materiale gërryese si graniti, kuarcit, dhe zhavorr lumi.
Kufizimet: Not designed as a primary crusher for runofquarry shot rock exceeding recommended feed size. Optimal performance requires consistent feed gradation and controlled moisture content to prevent screen blinding.
