The economic and environmental benefits of mobile crusher

AKURE, Nigeria - Oct. 28, 2024 - PRLog -- Introduction
The construction aggregates industry has witnessed revolutionary changes with the advancement of mobile crushing technology. Mobile Crusher offer unmatched versatility and flexibility compared to stationary plants, enabling on-site material processing with minimal waste. Beyond transportation efficiency gains, their deployment translates to tangible economic and environmental benefits. This report analyzes these benefits to provide industry stakeholders a clearer understanding of mobile crushers' value proposition.

Transportation Savings
Transportation is a major cost component in quarrying, accounting for 30-40% of total project expenditure. Mobile Crusher eliminate intermediate haulage of raw material to stationary plants for primary crushing, directly processing feed on location. This reduces payload mass and associated fuel usage. A typical three-axle mobile jaw crushing unit consumes 30-50% less diesel per tonne of material processed versus conventional trucking. Overall fuel savings conservatively equal $5/tonne even after factoring mobile unit operation costs.

Equipment Sizing Flexibility
Mobile Crusher (https://www.sbmchina.com/equipments/mobile-crusher.html) allow 'right-sizing' of equipment spreads to active quarry phases or short-term construction jobs versus fixed overcapacity. Components can be rapidly redeployed as resource extraction faces advance or jobs wind down. Capital is thus efficiently utilized versus idle stationary assets. Modular configurations further optimize equipment sizing. Selective addition of modules scales capacities, avoiding under/over-investment.

Stripping Reduction
On-site crushing shrinks the stripped overburden footprint around quarries by 25-45% depending on reserves depth. Overburden becomes easier to excavate productively without intermediate stockpiling. With fewer trucks mobilized, noise and dust pollution near communities also drops. Mobile units cut waste at the source, feeding only optimum sizes to downstream processes for maximum recovery. This enhances stripping ratio and extends pit life.

Land Usage
Stationary plants occupy large permanent tracts for plant facilities, stockyards and road access. In contrast, mobile solutions require minimal stationary infrastructure given their compact assemblies trucked into place. Temporary workspaces suffice as crushers relocate with extracting faces. Valuable lands are salvaged for alternate usage, boosting owners' real estate portfolios. Smaller footprints also aid operating in environmentally sensitive zones.

Energy Efficiency
On-site processing shortens material haul distances versus centralized stationary systems, reducing fuel consumption from haul trucks. Estimates indicate mobile crushing delivers 15-30% energy savings overall. Mobile units driven by Tier-4 Final certified engines further cut emissions by 60-90% through stringent after-treatment. Noise shielding enclosures maintain quietness near settlements. Optional hybrid-power technologies promise even lower environmental impact.

Waste Reduction
Crushing ahead of stockpiles eliminates oversize content buildup in storage. Broken rock requires minimal further processing before sale versus reclaimed larger fragments. Marketable product gradation is sooner achieved with fewer secondary crushing stages, enhancing stockpiles' commercial value. Sand and gravel producers report waste reductions of 15-30% from proper sizing enabled by mobile crushing.
