Indonesia Grogat Mine 1250t/h Coal Crushing System Project Equipment Delivered
Our WRK client in Indonesia is an enterprise specializing in EPC (Design, Procurement and Construction) projects and heavy equipment leasing services. With its technical strength and rich project management experience, it has undertaken the construction tasks of multiple large-scale comprehensive engineering projects.
In 2024, WRK Company has an important new engineering project – the 1,250-ton-per-hour coal crushing system project at the Grogat mine. This project has extremely high requirements for equipment, as the efficient implementation of coal crushing work is directly related to the production efficiency and operational benefits of the entire coal mine. The main equipment required for the project includes high-efficiency Feeder breaker and secondary crushing equipment. These devices need to have stable and reliable performance and be capable of continuous operation for a long time to meet the coal crushing capacity requirement of 1,250 tons per hour.
Our company provided WRK with the TP1400-16.92 Feeder Breaker and the 2PLF100300 Secondary Sizer. The TP1400-16.92 Feeder Breaker has an efficient feeding and crushing capacity. It can quickly and stably convey coal and conduct preliminary crushing, preparing for the subsequent secondary crushing. The 2PLF100300 Secondary Sizer is equipped with a powerful secondary crushing function, which can further refine the initially crushed coal to meet the particle size requirements of the project. These two types of equipment have demonstrated outstanding performance and stable operation in actual operation, fully meeting the requirements of the 1,250 tons per hour coal crushing system project of Grogat Mine, and providing a strong guarantee for the smooth progress of the project.
Core equipment parameters
Device Name: Feeder Breaker, Secondary Sizer
Equipment model: TP1400-16.92, 2PLF100300
Material processing: Coal
Processing capacity: 1250t/h
Feed particle size: Feeder Breaker: ≤500mm, Secondary Sizer: ≤300mm
Output particle size: Feeder Breaker: ≤300mm, Secondary Sizer: ≤80-130mm
Technical requirements for equipment
According to the crushing requirements proposed by the customer, the feed particle size of the Feeder Breaker should not exceed 500mm and the output particle size should not exceed 300mm. After the equipment was completed in production, it underwent an 8-hour no-load test run. During the test, the equipment operated smoothly, and the temperature rise of the bearings did not exceed 30° C. All performance indicators met the predetermined standards.
The feed particle size of the Secondary Sizer should not exceed 300mm, and the output particle size should be between 80mm and 130mm. After the equipment was completed in production, it also underwent a strict no-load test run process. During operation, the double-toothed roller rotates inward, and the toothed rollers do not come into contact. The equipment should run smoothly without severe vibration or abnormal sounds. The overall noise of the machine should not exceed 80dB(A), the temperature rise of the toothed roller bearings should not exceed 55°C, and there should be no oil leakage at the gearbox seal. All technical indicators proposed by the customer should be met.
Project technical adjustment
The client pointed out that the main technical challenge of this project lies in handling the special material properties of coal, which has a relatively high moisture content and is prone to adhering to the surface of the equipment, causing blockages. Our feeder breaker has a pre-screening function, which is not available in other brands of feeder breakers. Through pre-screening, fine particles in coal can be effectively screened out in advance, reducing the burden on subsequent crushing equipment and significantly improving the overall crushing efficiency. In addition, the secondary crusher is equipped with wear-resistant comb plates. During operation, it can promptly clean the materials adhering to the surface of the tooth rollers, effectively preventing coal from adhering during the crushing process, thereby reducing the occurrence of clogging and further enhancing the crushing efficiency.
