Sand Gravel Mining Assembly Plant Datasheet
1. PAINPOINT DRIVEN OPENING
Managing a sand and gravel mining operation means contending with persistent bottlenecks that directly erode profitability. Are you facing these common challenges?
Inconsistent Feed & Processing Bottlenecks: Variable feedstock from the pit leads to surges and starvation in your plant, causing constant manual adjustment, reduced throughput, and higher wear on crushers and screens.
Excessive Downtime for Maintenance: Traditional, hardwired plant designs with multiple conveyors and transfer points require frequent liner changes, belt repairs, and bearing replacements, leading to hundreds of unplanned downtime hours annually.
High Labor & Energy Intensity: Operating multiple standalone units—excavators, feeders, crushers, screens—requires significant fuel and operator hours per ton of final product.
Difficulty Meeting Spec & Product Contamination: Inefficient separation and screening processes result in offspec material or crosscontamination between product stockpiles, leading to rejected loads and revenue loss.
Limited Site Mobility & High Redeployment Costs: Fixed or semimobile plants are capitalintensive to relocate, locking you into a single deposit and preventing pursuit of new market opportunities.
What if your primary processing could be consolidated into a single, intelligent unit that addresses these issues directly? The solution lies in reevaluating your plant’s core assembly.
2. PRODUCT OVERVIEW: Modular Sand & Gravel Mining Assembly Plant
The Modular Sand & Gravel Mining Assembly Plant is an integrated processing system designed to replace traditional fixedplant setups. It combines primary crushing, screening, material washing (optional), and conveying into a single, trailermounted footprint. This configuration is engineered for rapid deployment and highvolume production in sand and gravel extraction.
Operational Workflow:
1. Integrated Feeding & Primary Crushing: Runofpit material is fed directly into the hopper module, which regulates flow to the integrated jaw or impact crusher.
2. Onboard Primary Screening: Crushed material is immediately conveyed to an integrated vibrating screen deck for primary size separation.
3. Product Routing & Stockpiling: Oversize material may be recirculated or diverted, while onspec sand and aggregate fractions are conveyed via onboard stacking conveyors to designated stockpiles. An optional integrated screw washer or cyclones can be incorporated for sand classification.
Application Scope:
Ideal for virgin aggregate deposits requiring primary reduction.
Suited for mediumtohigh volume operations (see specifications).
Effective for producing road base, concrete aggregate, and washed mason sand.
Limitations:
Not designed as a tertiary finishing plant for precision asphalt chips.
Maximum feed size is constrained by the model’s integrated crusher aperture.
Requires stable ground conditions for setup without extensive civil works.
3. CORE FEATURES
Unified Chassis Design | Technical Basis: Structural integrity analysis with centralized load distribution | Operational Benefit: Enables relocation within 2448 hours using standard heavy haul equipment | ROI Impact: Reduces site mobilization/demobilization costs by up to 60% compared to fixed plant construction.
