Key features:

1.The equipment boasts a simple installation foundation, requiring merely a flat surface for setup, with a hardened floor recommended for easy cleaning.

Its box-shaped frame structure allows for quick and efficient installation, streamlining operational readiness.

2.Additionally, the design offers a high degree of integrity, as all systems are integrated into one cohesive framework, with the exception of the finished material stacking belt conveyor.

This thoughtful configuration not only ensures the overall integrity of the equipment but also provides adequate space for maintenance and inspection.

The combination of convenience and security in this design makes it an ideal choice for various operational environments, ensuring both functionality and ease of use.

3.The equipment is designed for easy disassembly and transfer, ensuring high integrity for convenient storage and transportation at construction sites.

Its streamlined assembly process involves simply loosening the bottom fixing bolts and the hanging wire rope to pack the finished stacking belt conveyor into the main frame’s base.

This efficient design prioritizes mobility without compromising functionality.

4.Moreover,  a core screening system can enhance its working reliability because it employs a mixing principle reminiscent of a mixer. In this system, raw materials undergo continuous rolling and pushing thanks to spiral blades, which create friction among the materials inside the mixing drum, resulting in effective processing and dependable operation.

This combination of easy portability and robust performance makes the equipment an excellent choice for construction projects.

5.The flat design of the roller screen drum significantly enhances the material flow, achieving a flow rate more than five times that of traditional methods.

This unique configuration allows sand materials to be repeatedly rolled, ensuring thorough dispersion and effective screening.

Unlike inclined roller screens or vibrating screens that often lead to incomplete screening and mixing due to the squeezing of materials of varying sizes, this system minimizes those issues.

By efficiently separating and processing materials, the roller screen drum provides a more reliable and uniform screening solution, ultimately improving productivity and material quality.

This innovative approach to screening not only optimizes performance but also ensures a more consistent and accurate separation of materials.
