Vietnam 250 TPH Limestone Dry Sand Making Plant

Client from Vietnam, the primary contractor of asphalt high-way in the northern part, has contracted large numbers of asphalt high-way projects around Hanoi. Furthermore, his subsidiary corporation for environmental-brick is the biggest supplier for government project in Hanam province. Under such circumstance, they have been looking for an aggregate plant which can get sand and powder at the same time, where the sand is used in high-way construction and powder is used as the raw material for making brick.


Material: Limestone
Output Size: 0-3 mm
Environment Criteria: No-water System; Low-dust system
Application: Highway construction and Brick Making

Conventional technology for making sand adapts water-washing system to remove the fine powder from the sand, where the percentage of powder must be controlled below 7%. As a result, powder will be transformed into mud and going to waste and contamination.

By taking use of our grinder technology, Rayco R&D team designs a new sand making system without using water. What’s more, powder can be recycled and reused.
