Product technology uses special equipment such as jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, various vibrating screens and feeders to crush and screen construction waste.

After optimizing and strengthening the design, the product has higher strength, better efficiency and more compact structure. The product has the characteristics of reliable efficiency, good stability, strong maneuverability, low material transportation cost, flexible combination, strong adaptability and convenient maintenance. The products can be widely used in baking-free brick, road foundation, construction and other industries, which provides a new development idea for urban construction to embark on a virtuous circle.

It is urgent to strengthen the comprehensive utilization of construction waste.

The harm of construction waste occupies space, pollutes groundwater and air, and is difficult to decompose.
