1. PAINPOINT DRIVEN OPENING

Are you managing a quarry operation where ballast production is a critical yet problematic bottleneck? The challenges of producing consistent, specificationgrade railway ballast directly impact your profitability and project timelines. Common operational hurdles include:
High Wear Costs & Unplanned Downtime: Abrasive feed material rapidly degrades crusher components, leading to frequent maintenance stops and soaring spare parts inventories.
Inconsistent Product Gradation: Failure to maintain tight control over particle size distribution results in offspec material, causing rejection by rail authorities and costly reprocessing or stockpiling.
Low Throughput Efficiency: Inefficient crushing chambers and suboptimal kinematics fail to maximize yield of the required 2850mm aggregate fraction, wasting energy and potential revenue.
Excessive Fines Generation: Overcrushing creates an excess of 10mm fines, a waste byproduct that diminishes the saleable tonnage of premium ballast.

How do you increase the saleable tonnage of inspec ballast while controlling operational expenditure and minimizing disruptive downtime? The solution lies in selecting purposeengineered crushing equipment designed for the specific rigors of sustainable quarry ballast production.

2. PRODUCT OVERVIEW

This product line comprises heavyduty, stationary cone crushers specifically configured for secondary and tertiary crushing stages in hard rock quarries. Engineered for the continuous production of highquality railway ballast, these machines transform primary crushed feed (typically 150mm) into precisely graded, cubical aggregate.

Operational Workflow:
1. Primary crushed aggregate is fed into the crusher’s regulated feed hopper.
2. Material enters the optimized crushing chamber, where interparticle comminution and sustained compression break down particles along natural fracture lines.
3. The hydraulic adjustment system allows realtime control of the closedside setting (CSS) to finetune final product size.
4. Crushed material exits through the discharge opening, with oversize automatically recirculated via a closedloop system.
5. Final product is conveyed to screening decks for precise separation into ballast specification fractions.

Application Scope: Ideal for processing hard, abrasive igneous rock (granite, basalt) and limestone for railway ballast production. Best deployed after a primary jaw crusher.

Limitations: Not suitable for primary crushing of runofquarry rock or for processing highly cohesive, claybound materials without prior washing and preparation.
