1. PAINPOINT DRIVEN OPENING

Are unpredictable breakdowns and inconsistent output crippling your stone quarry's profitability? Managing a primary crushing station is a constant battle against high operating costs and unplanned interruptions. Key challenges include:

Excessive Downtime: Unplanned maintenance on crushers or feeders can halt your entire upstream operation, costing thousands per hour in lost production and idle labor.
Inconsistent Feed & Crusher Damage: Poorly regulated feed from the apron feeder leads to crusher cavity packing, uneven wear, and potential overload damage, resulting in premature component failure.
High Operational Costs: Rising energy consumption from inefficient material handling, combined with frequent replacement of wear parts under punishing conditions, erodes your margin.
Safety & Environmental Risks: Uncontrolled dust emissions at transfer points create health hazards and compliance issues, while manual adjustments expose personnel to moving machinery.

Is there a crushing plant solution that integrates robust primary crushing with intelligent feeding and material flow to deliver predictable tonnage and lower costperton?

2. PRODUCT OVERVIEW

The Stone Quarry Crushing Plant Assembly is a preengineered, heavyduty stationary crushing circuit designed for highvolume primary reduction of blasted quarry rock (limestone, granite, basalt). It integrates key components into a synchronized system for reliable firststage processing.

Operational Workflow:
1. Controlled Feed: Dump trucks discharge shot rock into a rugged vibrating grizzly feeder (VGF), which scalps out natural fines and regulates feed to the crusher.
2. Primary Reduction: Oversize material is conveyed to a highcapacity jaw crusher or primary gyratory crusher for initial size reduction.
3. Material Transport: Crushed product is discharged onto main conveyor systems for transport to secondary crushing or stockpiling.

Application Scope & Limitations:
Scope: Ideal for greenfield quarry development or replacement of aging, inefficient primary circuits. Suited for processing abrasive materials with compressive strengths up to 350 MPa.
Limitations: Not designed as a portable/mobile unit. Maximum feed size is determined by crusher opening; excessive clay or moisture content without preprocessing may cause handling challenges.

3. CORE FEATURES

HeavyDuty Vibrating Grizzly Feeder (VGF) | Technical Basis: Highstrength steel deck with adjustable grizzly bars | Operational Benefit: Removes subsize material before the crusher, reducing cavity volume and wear while providing consistent, regulated feed | ROI Impact: Increases crusher throughput by up to 15% and extends manganese wear life by an estimated 2030%

Modular BoltTogether Structure | Technical Basis: Fabricated steel modules with precisionmachined connection points | Operational Benefit: Significantly reduces field installation time and cost versus traditional welded designs; allows for future reconfiguration or relocation | ROI Impact: Can reduce plant assembly time by up to 40%, accelerating timetorevenue

Centralized Greasing & Lube System | Technical Basis: Automated, programmable lubrication points routed from a central station | Operational Benefit: Ensures critical bearings on the crusher and feeder receive consistent lubrication without manual intervention in hazardous areas | ROI Impact: Mitigates risk of catastrophic bearing failure, reducing unscheduled downtime and associated repair costs

Integrated Dust Suppression System | Technical Basis: Nozzle arrays at key transfer points (feeder discharge, crusher inlet/outlet) tied to plant operation | Operational Benefit: Actively controls respirable dust at the source, improving site visibility and air quality | ROI Impact: Lowers compliance risk and reduces housekeeping labor costs

PLCBased Control & Monitoring Panel | Technical Basis: Industrial programmable logic controller with HMI interface displaying amperage, temperature, and operational status | Operational Benefit: Provides operators with realtime visibility into plant performance for quick diagnostics and optimal load management | ROI Impact: Enables proactive maintenance scheduling and prevents minor issues from escalating into major failures

5. TECHNICAL SPECIFICATIONS

Capacity Range: Configurable from 400 to 1,500+ tons per hour (TPH), depending on rock characteristics.
Primary Crusher Options: Jaw Crusher (900x1200mm to 1500x2000mm) or Primary Gyratory Crusher.
Power Requirements: Total installed power typically ranges from 300 kW to 600 kW for main drives (crusher, feeders, conveyors). Specific requirements depend on configuration.
Material Specifications: Fabricated from S355JR structural steel; wear surfaces utilize AR400 steel liners; crusher components are highgrade cast steel or manganese.
Physical Dimensions: Footprint varies by capacity; a typical 800 TPH plant requires approximately 25m (L) x 15m (W) x 12m (H) foundation space.
Environmental Operating Range: Designed for ambient temperatures from 20°C to +45°C. Dust suppression system effective up to wind speeds of 8 m/s.

6. APPLICATION SCENARIOS

Granite Quarry Expansion | Challenge: An existing quarry needed to double primary capacity but had limited space for new foundations and a tight commissioning window of three months. Manual feeding led to frequent jaw crusher bridging. | Solution: Implementation of a compact Stone Quarry Crushing Plant Assembly with a boltedframe design installed on a prepared pad adjacent to the old plant. The integrated VGF was keyed for aggressive granite feed. | Results: The plant was operational in nine weeks. Crusher bridging incidents were eliminated by the VGF regulation. The site achieved its target of 850 TPH consistently within the scheduled timeframe.

Limestone Aggregate Production for Highway Project | Challenge: A contractor setting up a temporary quarry faced strict particulate matter (PM10) regulations and needed guaranteed weekly tonnage for asphalt plants. Downtime would delay the entire highway project. | Solution: A turnkey crushing plant assembly featuring an emphasized dust suppression package with sealed transfer points and automated spray systems was deployed alongside a robust jaw crusher known for low fines generation.| Results: The plant passed all environmental inspections without issue. It maintained availability above 92%, delivering over 35,000 tons of base material weekly as required throughout the project lifecycle.
