Jaw Crushers and Sand Making Machines: Powering Aggregate Production​

  The global construction boom demands high-quality aggregates, from road bases to concrete components. Behind every reliable infrastructure project lies efficient crushing and sand-making equipment. ,Sentai Machinery with 20 years of expertise, delivers jaw crushers and sand making machines that transform raw materials into essential building resources, trusted by contractors and miners worldwide.​

Jaw Crushers: The Foundation of Crushing​

    Jaw crushers serve as the workhorses of primary crushing, handling rocks, ores, and construction waste with ease. Our JC series jaw crushers feature a robust design with a deep crushing chamber and optimized toggle plate angle, ensuring a 10:1 reduction ratio—capable of breaking 500mm boulders into 50mm fragments in one pass.​

Key advantages include:​

    Durability: Manganese steel jaws resist wear, lasting 30% longer than standard alloys in granite crushing applications.​

    Efficiency: A 160kW motor delivers 150-300 tons/hour throughput, balancing power and energy consumption.​

    Safety: Hydraulic overload protection prevents damage from uncrushable materials, a critical feature in urban demolition sites.​

    In a quarry in Turkey, our JC1315 jaw crusher processes limestone 24/7, producing 200 tons/hour of aggregate for a highway project. Its simple maintenance design allows blade replacement in under 4 hours, minimizing downtime.​

Sand Making Machines: Precision in Particle Shaping​

    After primary crushing, sand making machines transform crushed stone into high-quality construction sand. Our VSI series vertical shaft impactors use centrifugal force to create cubical particles with consistent gradation—essential for concrete strength and workability.​

    Notable features:​

    Adjustable settings: Operators can modify rotor speed and feed rate to produce sand meeting ASTM C33 or EN 12620 standards.​

    Low wear: Ceramic liners reduce abrasion, extending service life when processing hard materials like basalt.​

    Water-saving: Optional dry processing systems eliminate the need for washing, saving 10,000 liters/day in arid regions.​

    A construction company in Dubai uses our VSI9526 to produce 120 tons/hour of fine sand. The machine’s ability to maintain 0-5mm particle distribution ensures their ready-mix concrete meets strict quality certifications, securing contracts for high-rise projects.​

Integrated Solutions: From Quarry to Construction Site​

    The synergy between jaw crushers and sand making machines creates a complete aggregate production line. In Malaysia, a mining operation combines our JC1110 jaw crusher with a VSI8518 sand maker:​

    The jaw crusher reduces granite from 300mm to 50mm.​

    A vibrating screen separates 5-20mm aggregate for road base.​

    Oversized material feeds into the sand maker, producing 0-5mm sand.​

    This setup increased their daily output by 40% compared to using separate systems, while lowering energy consumption by 18% through optimized material flow.​

Addressing Industry Challenges​

    Modern aggregate producers face two key challenges: sustainability and cost control. Our equipment addresses both:​

    Waste recycling: Jaw crushers efficiently process concrete rubble, while sand makers convert it into recycled sand—reducing reliance on natural resources. A recycling plant in Germany now processes 150 tons/day of demolition waste using this combination.​

    Operational savings: The durable design of our machines reduces maintenance costs by 25% over five years. Remote monitoring systems (optional) send real-time alerts for wear parts, preventing unexpected breakdowns.​

Future Trends in Aggregate Equipment​

    The industry is moving toward smarter, more flexible solutions. Our R&D focuses on:​

    Energy efficiency: Next-gen jaw crushers with variable frequency drives adjust power based on material hardness.​

    Modular design: Sand makers with quick-change rotors adapt to produce different sand grades in under an hour.​

    Eco-friendly features: Low-noise operation and dust suppression systems for urban worksites.​
