The Comprehensive Guide to Crushing and Sand-Making in the Aggregates Industry
The global demand for high-quality aggregates continues to rise, driven by infrastructure development, urbanization, and construction projects. The UK, with its stringent regulations on sustainable sourcing and recycled materials, presents a growing market for crushing and sand-making equipment. Used conveyor belts, crushers, and screens are increasingly sought after as cost-effective solutions for small-to-medium operations or temporary projects.
1. Primary Crushers: Jaw crushers and gyratory crushers break down large rocks (e.g., granite, basalt) into manageable sizes. Used models like LT105 or QJ341 are popular in the UK for their reliability.
2. Secondary/Tertiary Crushers: Cone crushers (e.g., , ) and impact crushers refine material further, producing cubical aggregates ideal for concrete or asphalt.
3. Sand-Making Machines: Vertical shaft impactors (VSIs) like or CV200 transform crushed stone into manufactured sand (M-sand), a sustainable alternative to river sand.
4. Screening & Conveying: Vibrating screens (e.g., Powerscreen Chieftain) segregate materials by size, while used conveyor belts (e.g., Dunlop, Fenner) transport bulk materials efficiently.
Q1: What’s the lifespan of a used cone crusher?
A: With proper maintenance (liner replacements, lubrication), a refurbished cone crusher can last 8–12 years.
Q2: Are used conveyor belts reliable?
A: Yes, if inspected for wear (cover thickness, splice integrity). Brands like Sempertrans offer durable used options.
Q3: How to choose between VSI and HSI for sand-making?
A: VSI produces finer sand with low fines content; HSI suits harder rocks but may generate more dust.
A Scottish operator integrated a used QH441 cone crusher and a second-hand Powerscreen Warrior screen to process 400 tph of basalt. By reusing equipment, they cut capital costs by 35% while meeting BS EN aggregate standards for a highway project.
The UK’s aggregates sector benefits from robust pre-owned markets—balancing cost-efficiency and sustainability without compromising output quality. Whether sourcing a used jaw crusher or conveyor system, prioritizing condition and application fit ensures long-term ROI in crushing and sand-making operations.
