LNZDS1030 Aggregate Shaping and Sand Making Plant - Applied in Shouzheng Sichuan

Driven by Sichuan's infrastructure boom and green building material policies, Sichuan Shouzheng's sand and gravel processing project prioritizes “quality improvement, efficiency enhancement, and precise product control.” As a leader in building materials processing, the company urgently needed an intelligent sand making machine to convert ordinary limestone into multi-spec high-quality aggregates. The adoption of Ninon's LNZDS1030 Aggregate Shaping and Sand-Making Equipment—an advanced manufactured sand production line centered on vertical shaft impact crushing technology and full-process intelligent control—has solved core production challenges, becoming the “core driver” for dual upgrades in capacity and quality.

Limestone, a common raw material for sand making, has moderate hardness but tends to produce acicular and flaky particles, leading to disordered gradation in finished products from traditional equipment that fails to meet high-end construction demands. Ninon's sand making machine integrates an innovative “stone-on-stone + stone-on-iron” dual-mode vertical shaft impact crusher, with a cavity optimized for limestone. Materials projected by the high-speed impeller undergo inter-particle collision and targeted impact, reducing acicular particles at the source. This design not only delivers round cubic finished sand but also extends wearing parts' service life by 40% compared to traditional models, cutting costs for the manufactured sand production line.

At Sichuan Shouzheng's site, limestone from raw material silos is fully processed by the sand making machine, yielding six specifications: 26mm, 16mm, 11mm, 6mm, 3.5mm, and 0-3.5mm—forming a complete system from coarse aggregates to fine sand. The 16-26mm fraction suits expressway subgrades, 3.5-6mm fine sand for high-grade concrete, and 0-3.5mm stone powder for mortar, achieving full resource utilization aligned with green production goals.

The manufactured sand production line's efficiency hinges on its PLC intelligent control system. The central control screen displays real-time data—operating temperature, vibration, and output—allowing touch-based parameter adjustments. Fault early warning minimizes unplanned downtime, while automatic production reports support precise scheduling. Post-commissioning, the sand making machine maintains a stable daily output, with finished product qualification rate rising from 85% to 98%, resolving specification fluctuations and instability.

As a benchmark intelligent sand making machine, Ninon's LNZDS1030 meets Sichuan Shouzheng's multi-spec needs and Sichuan's strict environmental standards via full-enclosed design and negative pressure dust removal. This cooperation showcases the manufactured sand production line's technical strength and contributes to Sichuan's infrastructure development.

From limestone to high-quality manufactured sand, Ninon's sand making machine bridges traditional processing and intelligent control for Sichuan Shouzheng. Future innovations will bring more tailored manufactured sand production line solutions, empowering enterprises to achieve "resource value increment and efficiency improvement.”
