El desafío: Lo que el cliente necesitaba
A building materials producer in northern Vietnam wanted to enter the booming Hanoi construction market. They needed to process medium-hard limestone into two distinct high-end products simultaneously. Their target was high-quality concrete aggregate and uniform manufactured sand.
Traditional crushing lines produced too many flaky and elongated stone particles. Poor aggregate shape reduces concrete strength and fails strict municipal construction codes. The client required a high-efficiency system to control the flake rate strictly under 6%. They also demanded a precise sand-grading curve for premium concrete mixing.
La solución: Sunwe Dual-Purpose Production Line
Sunwe installed an integrated plant to achieve perfect aggregate shaping and precise sand making.
Paso 1: Secondary Aggregate Shaping
The material moves into our secondary Impact Crusher after primary reduction. This impact crusher uses high-speed blow bars to shape the limestone cubes. This process breaks weak edges and eliminates elongated particles effectively.
Paso 2: High-Precision Sand Making
Part of the crushed stone flows into our advanced VSI Sand Making Machine. The VSI crusher uses rock-on-rock crushing technology to grind stones into sand. This method produces highly uniform, cubical manufactured sand (M-Sand).
Paso 3: High-Precision Sifting
Fine-mesh vibrating screens separate the final outputs into exact commercial sizes. The system washes and sizes the sand to meet international blending standards.
Comparación de rendimiento
The table below displays the production quality before and after installing the Sunwe line.
| Indicador clave de rendimiento (KPI) | Conventional Crushing Line | Sunwe High-Precision Line | Mejora neta |
| Salida por hora (TPH) | 130 t/h | 180 t/h | +38.4% Capacity Boost |
| Flaky & Elongated Particles | 15% – 18% | Bajo 6% (Estricto) | Premium Cubical Shapes |
| M-Sand Fineness Modulus | 3.4 (Too Coarse) | 2.6 – 2.8 (Ideal) | Perfect Grading Curve |
| Market Selling Price (per Ton) | Base Local Price | Premium Market Price | +25% Higher Profit Margin |
Los resultados y el valor para el cliente
The Sunwe dual-purpose line has run successfully in Vietnam for over 10 meses. It easily delivers a reliable 180 TPH total yield.
The strict control of flaky particles under 6% opens doors to premium supply contracts. Our advanced VSI machine creates excellent cubical sand with perfect fineness. Consequently, the client successfully captures both the high-end concrete aggregate and fine-sand markets in Hanoi.
“Sunwe sand-making line transformed our business model in Vietnam. Their VSI crusher produces beautiful cubical sand that our concrete clients love. We easily achieved a flake rate under 6%, which doubled our high-end sales.”- Señor. Nguyen Van Thang, Production Director
