Hongtai Concrete Co., Ltd. (located in Nankang District, Ganzhou City, Jiangxi Province) is a key local precast concrete enterprise founded in 2011, operating multiple concrete mixing lines. As Ganzhou's infrastructure and prefabricated building sectors boom, demand for high-quality aggregate and manufactured sand has soared. However, the company faced critical issues: externally purchased aggregates had unstable quality and inconsistent gradation, undermining concrete strength and workability; long-distance aggregate transportation pushed logistics costs to over 35% of raw material expenses. To resolve these, Hongtai selected Ninon's DS200 sand making machine as the core of its integrated manufactured sand production line, achieving self-sufficiency in premium aggregate and manufactured sand.

The customized DS200 manufactured sand production line integrates crushing, shaping, screening, and dust removal, with standout technical strengths:

◆Superior Finished Products: The sand making machine adopts vertical shaft impact crushing, realizing "crushing + shaping" in one pass. Finished aggregates are cubical with needle-like particle content ≤5% (far below GB/T 14685-2023's ≤10% for C60 concrete). Manufactured sand has a stable fineness modulus of 2.3-3.0 and controlled stone powder content (3-5%), meeting high-grade concrete requirements for municipal and infrastructure projects.

◆Efficient & Energy-Saving: This manufactured sand production line perfectly matches Hongtai's annual concrete output needs, balancing productivity and energy efficiency.

◆Eco-Friendly & Intelligent: The fully enclosed sand making machine, paired with a high-efficiency pulse dust collector, reduces emissions to ≤8mg/m³, exceeding Ganzhou's environmental standards. Its intelligent system enables real-time gradation and stone powder adjustment, 7×24 unattended operation, and remote monitoring, cutting maintenance costs by 40%.

Since commissioning, the DS200 manufactured sand production line has delivered remarkable results: Concrete product qualification rate rose from 95% to 99.8%. Relying on the sand making machine's precise control, Hongtai successfully produced C60 high-grade concrete, applied in Nankang's infrastructure renovation projects and praised by clients for excellent workability and strength stability.

“The DS200 sand making machine completely solved our long-standing aggregate quality instability and environmental pressure,” noted Hongtai'[s production director. “The manufactured sand production line's performance is reliable, and its intelligent control simplifies operation. Ninon's sand making machine boosts our product competitiveness and lays a foundation for sustainable development. We will deepen cooperation for future capacity expansion.”

As a core product of Fujian Ninon Technology Co., Ltd., the DS series sand making machines focus on high-quality manufactured sand production. Equipped with patented aggregate shaping and stone powder control technologies, they are widely used in concrete enterprises, infrastructure projects, and building materials bases nationwide. Over 100 sets of this manufactured sand production line have been delivered and put into operation, earning industry recognition for “high efficiency, energy saving, and environmental friendliness.”
