1. PAINPOINT DRIVEN OPENING

Are you managing unpredictable pit geology, fluctuating feed gradation, and the constant pressure to reduce cost per ton? Inconsistent feed material leads to inefficient screening, premature wear on downstream crushers, and excessive production of offspec material. This variability directly impacts your bottom line through increased downtime for screen media changes, higher energy consumption from processing recirculating loads, and lost revenue from missed gradation targets.

How can you stabilize your operation when faced with heterogeneous sand and gravel deposits? What system can adapt to changing material conditions without requiring complete circuit reconfiguration? The solution lies in a purposedesigned Certified Sand Gravel Mining Design Service that transforms raw deposit variability into predictable, profitable output.

2. PRODUCT OVERVIEW

A Certified Sand Gravel Mining Design Service is a comprehensive engineering package that delivers a fully optimized processing plant layout and equipment specification. It moves beyond standard equipment selection to create a cohesive system engineered for your specific deposit’s characteristics. The operational workflow begins with (1) detailed site and material analysis, leading to (2) dynamic process simulation and flow sheet development, followed by (3) precise equipment sizing and integration planning, (4) civil and structural design coordination, and concluding with (5) commissioning protocols and operational training matrices. This service is scoped for greenfield sites, major brownfield expansions, or operations requiring fundamental efficiency overhauls. It is not intended for minor, singleequipment replacement projects.

6. APPLICATION SCENARIOS

Aggregate Producer Coastal Deposit Expansion

Challenge: A producer expanding into a new pit zone faced highly variable strata with intermittent clay lenses and ironstone bands within sand/gravel beds. The standard plant design risked frequent blinding of wash screens.
Solution: Implementation of the Certified Sand Gravel Mining Design Service included detailed core sampling leading to the specification of a robust scrubbing circuit with a log washer module ahead of screening.
Results: The tailored system maintained target production of 400 TPH even with poor feed conditions. Results included a reduction in screen media change frequency from every 3 weeks to every 8 weeks.

Public Works Contractor OnSite Processing Project

Challenge: A large infrastructure project required specific fill materials from onsite excavation but had severe space constraints preventing a traditional linear plant layout.
Solution:The Certified Sand Gravel Mining Design Service developed a compact vertical stacking plant design using highfrequency screens within steelframed modules.
Results:The spaceefficient design fit within the allowable site footprint while producing three separate certified materials concurrently.This eliminated offsite purchase of select granular fill,saving an estimated $18/ton in material costs.
