150 t/h River Stone Crushing Plant in Indonesia

Introduction

An Indonesian aggregate producer needed to expand into manufactured sand from locally available river pebbles. DC Machinery designed a three-stage crushing and sand-making line that produces both crushed aggregate and high-quality manufactured sand from a single plant, using wear components optimized for abrasive river stone.

Challenge

River pebbles are fine-textured yet highly abrasive, causing standard crushers to suffer rapid wear and fatigue. The client sought a production line capable of producing crushed aggregate while keeping operating costs under control.

Solution

The crushing production line we designed employs a PE series jaw crusher for primary crushing and a Symons cone crusher for secondary and tertiary crushing; it is also equipped with screening equipment for material classification and utilizes wear-resistant parts specifically selected to handle the abrasive nature of river pebbles.

Outcome

• 150 t/h combined aggregate and manufactured sand output
• wear parts optimized for abrasive river pebble, extending service intervals
• Local commissioning team supported installation on site
• Additional plant ordered by the customer after 6 months
• Documented commissioning report: no-load and load trial run records with bearing temperature, vibration and power draw.
• Spare-parts kit supplied with the plant (jaw plates, mantle, concave) so a worn part never stops production.
