Recently, EXCT has once again won a complete set of EPC project for a coal crushing station in the Xiasiqi area of Aceh Province, Indonesia. The project focuses on coal crushing, belt transportation, and large-scale storage requirements. We provide customers with a complete station solution covering civil engineering, steel structure, belt transportation system, and crushing equipment system.
The storage equipment for this project adopts a 42-meter fixed stacker conveyor with a processing capacity of 1,000 t/h and a total horizontal rotation range of 220°, helping customers achieve large-scale coal storage.
Prior to this, the customer had purchased a mineral sizer from our company based on the pleasant cooperation in the previous project. Based on this, the customer entrusted this entire set of coal crushing station EPC project to us again.
From single equipment to complete station EPC
This project's client is located in the Xiasiqi area of Aceh Province, Indonesia. It is one of the largest and most powerful open-pit coal mine developers in Indonesia. In response to the client's needs, EXCT undertook the project under the EPC total contracting model, and the service content covers:
- Civil engineering: foundation construction, site leveling, and support structure construction;
- Steel structure engineering: design, fabrication, and on-site installation of the steel structure frame;
- Belt transportation system: planning of the entire plant's material transportation routes and equipment installation;
- Crushing equipment system: selection of main equipment, automation control, and installation and commissioning of supporting facilities.
Project conditions
The Aceh region has a tropical rainforest climate, with high temperatures, abundant rainfall, and humid environment. This poses extremely high requirements for equipment corrosion prevention, moisture resistance, and continuous operation stability. EXCT focused on strengthening the environmental adaptability design of the equipment and system in the complete station plan, considering corrosion prevention, moisture resistance, and long-term continuous operation stability, to ensure the system operates reliably in high-temperature and high-humidity environments.
Process flow
The project adopts the process flow of "buffer silo - feeder breaker - belt conveyor - mineral sizer - belt conveyor - Stacker Conveyor".
The materials enter the feeder breaker from the silo for the initial crushing, then are sent to the mineral sizer via the belt conveyor for the secondary crushing, and finally enter the Stacker Conveyor through the belt conveying system to complete the storage. The entire process line is closely connected, covering key links such as receiving, crushing, transportation and storage.
As the core storage equipment of the project, the 42-meter fixed-arm stacker crane will undertake the task of large-scale coal storage. Its horizontal rotation range is 110° on the left and 110° on the right, with a total horizontal rotation range of 220°. Combined with the 42-meter arm length and 12.65-meter discharge height, it can effectively expand the storage coverage, improve the flexibility of on-site storage operations, and meet the large-scale storage requirements of customers.

Project Highlights
A 42-meter-long stacker with an expanded storage coverage radius, meeting the requirements for large-scale storage;
A total horizontal rotation of 220°, with 110° each on the left and right, enhancing the flexibility of storage operations;
A processing capacity of 1000 t/h and a design capacity of 1200 t/h, leaving room for the increase of the mining area's production capacity;
EPC full-chain service, covering civil engineering, steel structure, belt conveyors and crushing equipment systems;
Adapted to tropical rainforest conditions, with a focus on strengthening anti-corrosion, moisture-proof and continuous operation stability.
Conclusion
From the initial equipment cooperation to the current full station EPC turnkey project, the repeated choice of the Indonesian client is the highest recognition of EXCT's technical strength, manufacturing quality and project management capabilities. In the future, EXCT will continue to focus on the actual working conditions and production capacity requirements of the clients, providing reliable full station solutions and full-process services to help the Indonesian coal projects achieve efficient and stable operation.
