Crushing And Screening Equipment
Crushing and Screening Equipment: Maximizing Throughput and Minimizing Downtime
The Operational Challenges You Face Daily
Every hour of unscheduled downtime in your crushing circuit costs you an average of $8,000–$15,000 in lost production, en fonction de votre tonnage et de la valeur matérielle. Plant managers across the aggregates and mining sectors consistently report three critical pain points:
- Classement incohérent des produits leading to rejected loads and recrushing cycles that eat 12–18% of your operational budget.
- Premature wear on wear parts — manganese and blow bars failing at 60–70% of rated life due to improper feed distribution and inadequate screening efficiency.
- Bottlenecked screening decks that reduce your crusher's effective capacity by up to 25%, forcing you to run secondary equipment longer and increase fuel consumption.
- Washing screen module (adds 15–20% to system cost) — for claycontaminated feed
- Séparateur magnétique for recycled metal removal ($45,000–60 000 $)
- Extended wear liner package avec 22% acier au manganèse ($28,000–35 000$)
- Solarassisted power system pour les sites distants ($120,000–$180,000)
- Plan de maintenance préventive: $4,500/month — includes quarterly inspections, service de lubrification, and wear measurement reports
- Contrat de service complet: $12,000/month — includes all scheduled maintenance, travail, and replacement wear parts (excluding manganese liners)
- Garantie de performance: $18,000/month — includes full service plus a contractual throughput guarantee (95% de capacité nominale) with credits for shortfalls
- Location-exploitation: 36–Conditions de 60 mois, $22,000–$35,000/month depending on package and residual value
- Prêt d'équipement: 10–20% down payment, 5–7 year terms at 6–9% APR based on credit profile
- Louer pour posséder: 24mois de location avec 70% of payments applied toward purchase
Your engineering contractors are demanding tighter spec compliance. Your buyers are pushing for lower costperton. Your maintenance teams are stretched thin. The question is not whether you need better crushing and screening equipment — it is whether your current setup can deliver the throughput, cohérence, and uptime your contracts require.
Présentation du produit: Integrated Crushing and Screening Systems
This crushing and screening equipment line comprises primary jaw crushers, concasseurs à cône secondaires, and highfrequency inclined screens engineered as a modular, interoperable system. The workflow operates as follows:
1. Réduction primaire — Runofmine or quarry feed (jusqu'à 800 mm) entre dans le concasseur à mâchoires, reducing material to 150–200 mm at throughput rates of 250–600 tph.
2. Scalping and PreScreening — A heavyduty vibrating grizzly feeder removes fines (<40 mm) avant le stade secondaire, eliminating 15–20% of unnecessary crusher load.
3. Concassage secondaire — The cone crusher receives the scalped material, producing a consistent 20–65 mm product with a cubical shape index above 90%.
4. Dépistage et classification — Dualdeck inclined screens (18°–20°) separate material into three fractions: surdimensionné (recirculé), taille moyenne (produit fini), et des amendes (stockpiled or further processed).
5. Recirculation Loop — Oversize material returns via a closedcircuit conveyor, assurer 100% of feed passes final spec.
Champ d'application: This system is suitable for hard rock (granit, basalte, quartzite), béton et asphalte recyclés, et minerais abrasifs avec une résistance à la compression allant jusqu'à 400 MPa. It is not recommended for clayheavy, matériaux collants dépassant 12% moisture content without a washing screen addon.

FAQ
Q: Can this crushing and screening equipment handle abrasive materials like basalt or river gravel?
UN: Oui. The standard configuration includes 18% manganese liners rated for abrasive feed. Pour les matériaux dépassant 25% teneur en silice, we recommend the extended wear liner package, which field testing shows extends liner life by an additional 15–20% in basalt applications.
Q: Quelle est la superficie minimale du site requise pour l'installation?
UN: The complete system requires a footprint of approximately 45 m × 30 m, including stockpile areas and access roads. The modular skid design allows for a compact "S" configuration that reduces this to 35 m × 25 m if space is constrained.
Q: How does the automated loadsensing feed control affect my existing operators?
UN: The system operates in an advisory mode for the first 30 jours, allowing operators to override settings. After this period, most operators prefer the automated mode because it reduces their workload and eliminates the constant manual adjustments previously required. Training is included in the purchase price.
Q: Quel est le délai typique entre la commande et la mise en service?
UN: Le délai de livraison standard est de 16 à 20 semaines à compter de la confirmation de la commande. Cela inclut la fabrication, quality control testing, et expédition. Site preparation and installation typically require an additional 2–3 weeks, with commissioning completed within 5 working days of mechanical completion.
Q: Can this system be integrated with my existing crushers or screens?
UN: Oui. The modular frame and standardized conveyor connections allow integration with most major brands (Racines, Sandvik, Terex) using adapter kits. Our engineering team will assess your existing equipment and provide a compatibility report before you commit to purchase.
Q: Quelle couverture de garantie est fournie?
UN: La garantie standard couvre 24 mois ou 8,000 heures d'ouverture, selon la première éventualité, for structural components and drive systems. Pièces d'usure (doublures, écrans, ceintures) sont couverts pour 6 mois ou 2,000 hours against manufacturing defects, pas d'usure normale. Garanties étendues jusqu'à 60 months are available on the structural frame.
Q: How does the equipment perform in extreme cold or highaltitude conditions?
UN: The standard package operates to 20°C. Pour les environnements plus froids, we offer a coldclimate package with heated hydraulic reservoirs, lubrifiants pour temps froid, and insulated control cabinets rated to 40°C. Pour les altitudes supérieures 3,000 mètres, motors are derated by 10–15% per 1,000 mètres au-dessus du niveau de la mer, and we recommend the highaltitude package to maintain full rated capacity.
Q: What training do you provide for maintenance teams?
UN: The purchase includes a 5day onsite training program covering mechanical maintenance, systèmes hydrauliques, electrical diagnostics, and predictive maintenance techniques using the remote monitoring data. This training is conducted by our field service engineers and includes handson exercises with your actual equipment. Additional advanced training modules are available at $3,500 par jour.
