1. PAINPOINT DRIVEN OPENING

Are your aggregate production targets consistently undermined by inconsistent feed material, unplanned downtime, and spiraling operational costs? For commercial quarry operators in Lagos and beyond, the challenges of maintaining a profitable and compliant site are multifaceted. Consider these common operational hurdles:
Variable Feed & Product Inconsistency: Fluctuations in rock hardness and size from the blast face lead to uneven crusher loading, causing bottlenecks, premature wear, and offspec product that fails to meet stringent project or regulatory standards.
Excessive Downtime for Maintenance: Traditional plant configurations often require full shutdowns for routine servicing of key components like crusher liners or screen meshes, directly costing you hundreds of thousands of Naira in lost production per day.
High Operational & Energy Costs: Inefficient crushing circuits and standalone units consume excessive power per ton of output. Coupled with high wear part consumption from suboptimal rockonsteel or steelonsteel reduction, your profit margins are continuously eroded.
Space & Logistics Constraints: Setting up a traditional multistage crushing and screening plant requires significant land area and complex logistical planning for foundation work and interequipment conveyancing—a major challenge in secured, approved sites.

How do you increase throughput while controlling capex and opex? Can you achieve a more consistent product grade to command better pricing? Is there a solution that reduces your site’s physical footprint without compromising capacity?

2. PRODUCT OVERVIEW

The Mobile TrackMounted Cone Crusher Plant represents a advanced class of secondary and tertiary crushing solution designed for highvolume aggregate production in quarry applications. This integrated system combines a highperformance cone crusher, onboard vibrating screen, and recirculating conveyor on a single tracked chassis.

Operational Workflow:
1. Primary Feed: Sized material (typically 8" or 200mm) from a primary jaw crusher is fed directly into the plant via an integrated hopper or from a separate loader.
2. ClosedCircuit Crushing & Screening: The cone crusher reduces the material, which is then discharged onto the onboard screen. Onspec product is separated out, while oversized material is recirculated back to the crusher via a cross conveyor or returned to the feed conveyor.
3. Product Stockpiling: Correctly sized aggregates are conveyed to designated stockpiles for future use or direct loading.

Application Scope: Ideal for producing precisely graded aggregates (e.g., 3/8", 1/2", 3/4" stone) for asphalt production, concrete batching, and road base construction. It is particularly effective for processing hard, abrasive igneous rock (e.g., granite) common in many regions.

Limitations: Not designed as a primary breaker for runofquarry shot rock. Optimal performance requires prescreened feed to remove fines. Maximum feed size is determined by the specific cone crusher model installed.

Granite Quarry Expansion Project

Challenge: A largescale quarry operator needed to establish secondary/tertiary crushing capacity at a new pit within their existing licensed boundary but faced prohibitive cost estimates for fixed plant infrastructure due to difficult terrain.
Solution: Deployment of two mobile trackmounted cone crusher plants configured in series.
Results: The units were operational within two days of arrival onsite. The setup eliminated need for concrete foundations and extensive conveying structures. The quarry achieved full secondary crushing capacity at the new face within one week, maintaining overall site output without interruption.

Urban Aggregate Supply Contract

Challenge: A contractor winning multiple concrete batching supply contracts across Lagos required consistent production of multiple aggregate specifications but had limited longterm land lease options for a fixed plant.
