This project is a typical limestone production line project. It forms a closed-loop circulation system from exploration --Primary crushing--secondary crushing-sand making -sieving-conveying-mixing plant-finished mixer truck, which implements a three-shift 24-hour continuous production, its conveyor system covers the entire mining area from explore site to crushing, screening, finished material stock yard, mixing plant, and has laid a solid foundation for the continuous production of the project. This project is the largest self-operated limestone crushing production line in local, providing a large amount of material requirements for local infrastructure construction and making an outstanding contribution to local city construction.
All bulk material conveyors adopt the top domestic external electric roller, stable single-beam main structure, domestic first-grade brand belts, comprehensively maintained and repaired double-sided grille walkway, top-grade deviation rope switch protection, open dust cover, first-class iron remover, metal detector and other high standard configuration as per user’s requirements.Its design process strictly meets national standards, and the configuration requirements are at domestic first-class level.
The screening and conveying system handles the materials are crushed rock and sand at various stages, and the finished products are used in the mixing splant. Therefore, the various parts of the system, especially the vibration feeder, vibrating screen, conveyor head chute, slide pipe, wear-resistant liners, etc, can not only meet the requirements for smooth passing the materials during the maximum conveying efficiency operation, but also meet the requirements of materials for impact wear on components, which ensure normal discharging and conveying safely, conveniently with stable efficiency.
The system equipment is equipped with perfect safety protection devices and necessary safety protection facilities to ensure the safe operation of the equipment. The working status of the safety protection device of the whole screening and conveying equipment can be realized by the centralized control station system on the spot, and can also be manually operated at the machine side.
1. Typical stone crushing project, strictly adopt national standards and environmental protection requirements;
2.Electric roller drives, improve the operation efficiency of the conveying system, reduce the damage to drive device caused by the environment, and facilitate the maintenance;
3. The plant design and power calculation are accurate, and the overall stage is closely linked;
4. The electric droller is equipped with a backstop to prevent the belt conveyor from slipping.
5. The system covers all conveyor belt models and length;
