A Vietnamese construction company in Quang Ninh Province needs to produce high-quality sand and aggregates from hard mountain rocks for local infrastructure projects.
• Location: Vietnam
• Material: Mountain rock 40-100mm
• Capacity: 15 tons per hour
• Final product: 0-5mm sand (for concrete) + 5-10mm aggregate (for road surface)
The customer's existing hammer crusher generates excessive dust and uneven particle size, resulting in a high scrap rate. SMAT's solution was to provide the customer with the 2PG0640 double-roller crusher. Heavy-duty rollers, high manganese steel rollers, and replaceable worn sections. Hydraulic clearance adjustment (2-8mm), precise control.
According to customer requirements, equipped a dust removal system to meet local environmental protection needs, and a vibrating screen for efficient particle size separation.

The output of 0-5mm sand (90% cubic) + 5-10mm aggregate complies with the Vietnamese TCVN 7570 standard.
The production capacity is 16 tons per hour (exceeding the target) to enhance production efficiency.
The power consumption is 30kw (low energy consumption), which is 50% lower than that of hammer crushers.
Dust emissions of less than 15mg /m³ (with water spray) comply with Vietnam's environmental protection regulations.
“The low maintenance and stable output of the roller crusher enable us to provide high-quality sand for a major highway project. The dust control system has changed the safety of our workers.”
