1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing a sand and gravel operation where inconsistent feed material, temps d'arrêt excessif, et la hausse des coûts opérationnels érode vos marges? The challenges of a traditional fixed plant are welldocumented: inflexible layouts that cannot adapt to changing deposit profiles, lengthy setup times that delay production, and high maintenance costs from component wear due to unprocessed oversize material. How much revenue is lost each season during plant relocation and reassembly? What is the true cost of unscheduled downtime caused by crusher blockages or conveyor failures? How can you improve your yield of spec product from variable pit material without constant manual intervention? The solution lies in moving from a static setup to a purposeengineered, modular system.

2. APERÇU DU PRODUIT

The Bespoke Sand & Gravel Mining Assembly Plant is a fully modular, semimobile processing system engineered for the specific demands of aggregate extraction. It is not a single machine but an integrated circuit of preengineered modules that can be rapidly configured onsite. Le flux de travail opérationnel est rationalisé: (1) Primary feeding and scalping to remove deleterious oversize; (2) Primary crushing and initial sizing; (3) Secondary screening and classification; (4) Tertiary crushing/sanding circuit (si configuré); (5) Final sorting and stockpiling. This plant is designed for commercialscale sand and gravel pits, alluvial deposits, and construction aggregate recycling operations. Its primary limitation is its designed maximum feed size and hourly tonnage capacity, which are specified during the engineering phase to match your reserve characteristics.

6. SCÉNARIOS D'APPLICATION

Aggregate Producer with Multiple Pit Sites | Défi: A regional producer faced significant lost time and cost each time their fixed plant needed moving between depleted and new sites, ce qui entraîne plus de 6 weeks of nonrevenue generating activity per year. | Solution: Implementation of a bespoke modular assembly plant with five core processing modules. | Résultats: Plant relocation time between permitted sites reduced to an average of 12 jours. This increased annual operational availability by approximately 8%, directly contributing to higher yearly output without capital expenditure on additional fixed plants.

Sable & Gravel Dredging Operation | Défi: Variable feed material from a dredge containing large cobbles and organic debris caused chronic blockages in the primary crusher, requiring daily shutdowns for clearing and increasing maintenance labor by two fulltime equivalents. | Solution: Integration of an aggressive heavyduty prescalping module with a dedicated waste conveyor ahead of the crushing circuit in their bespoke plant design.| Résultats: Oversizerelated stoppages were reduced by over 90%. The operation reallocated maintenance labor to preventive tasks, achieving a more consistent feed rate and improving overall circuit efficiency by an estimated 15%.

8. FAQ

1. How quickly can we modify the plant layout if our deposit characteristics change?
The modular nature allows for reconfiguration within days. For example, adding a washing screw or rerouting conveyors can be achieved by repositioning skidmounted units rather than cutting/welding structural steel.

2. What level of site preparation is required compared to a traditional fixed plant?
Site preparation is significantly reduced as no extensive concrete foundations are needed beyond simple levelling pads or sleeper arrangements for module stability.

3. Is the control system compatible with our existing fleet management software?
The SCADA system provides standard OPC data outputs that can typically be integrated into broader mine management platforms via established industrial communication protocols.

4. What are the lead times from order to commissioning?
Lead times vary by configuration complexity but are generally shorter than fixed plants due to parallel fabrication of modules—typically ranging from [Industry Standard Lead Time] months upon final design approval.

5. How does the operational cost per ton compare over a fiveyear period?
While initial investment may be comparable to some fixed systems industry testing demonstrates that savings in redeployment costs reduced downtime lower wear part consumption typically result in lower total cost ownership over five years particularly multisite operations

6 . Are these plants suitable regions strict environmental regulations noise dust?
Yes They designed incorporate enclosed conveyors covered screens integrated dust suppression spray systems Optional noise abatement kits available meet specific local decibel limits

7 . What happens one module requires major servicing?
