The CONSTMACH JS-3 mobile jaw and secondary impact crushing plant represents a significant advancement in portable crushing technology, delivering production capacities between 250 and 300 tons per hour. This dual-chassis system combines primary jaw crushing with secondary impact crushing and integrated screening capabilities, making it an ideal solution for processing materials ranging from limestone and riverstone to dolomite and basalt. The plant's engineering focuses on operational efficiency, rapid deployment, and the ability to produce high-quality aggregates with excellent cubical shapes that meet demanding specifications for concrete production.
What sets the JS-3 apart is its thoughtful dual-chassis configuration. The first chassis houses the CJC-110 primary jaw crusher, which accepts material up to 1,050 x 800 mm in size through a vibrating feeder system. The feeding hopper integration includes a bypass conveyor that efficiently removes soil and fine materials before they reach the crusher, preventing unnecessary wear and maintaining optimal crushing performance. This chassis sits on a wheeled mobile platform equipped with hydraulic legs for quick leveling and stability during operation. The dust removal system integrated into this stage ensures cleaner operation and better working conditions on site.
The second chassis carries the CSI-1215 secondary impact crusher, which is where the JS-3 truly demonstrates its capabilities. This impact crusher features a specialized design that produces aggregates with superior cubical characteristics, which is particularly valuable for concrete production where particle shape directly affects strength and workability. The three-deck vibrating screen allows operators to produce three or four different product fractions simultaneously, giving flexibility to meet various market demands from a single setup. A feedback conveyor connects the screen back to the secondary impact crusher, enabling recirculation of oversized material for further reduction. Fold-up stockpile conveyors complete this chassis, and like the primary unit, it includes its own hydraulic leg system and dust suppression equipment.
Operation of the JS-3 mobile crusher is streamlined through a sophisticated automation system built around premium SIEMENS and SCHNEIDER electronic components with PLC control. The entire plant operates via a tablet controller, giving operators precise command over all functions from a single interface. This level of automation reduces the learning curve and minimizes the potential for operational errors while maximizing productivity. The system monitors performance parameters continuously, allowing operators to adjust settings in real-time to optimize output quality and throughput based on material characteristics.
One of the most practical advantages of the JS-3 mobile crushing plant is its rapid deployment capability. The plant can be operational in remarkably short time frames, particularly when equipped with the optional hydraulic opening mechanisms for the feeding hopper and stock conveyors. With these features, the plant can be set up without requiring external equipment like cranes or loaders, reducing mobilization costs and time significantly. This self-sufficiency is especially valuable when moving between job sites or when working in remote locations where support equipment availability may be limited.
The JS-3's design adheres to international road transport regulations, with dimensions that allow movement by a single tractor unit. The first chassis measures 10 meters in length, 3.2 meters in width, and 4.5 meters in height, while the second extends to 16 meters long with the same width and height. Combined, the plant weighs approximately 80,000 kilograms across both chassis. This portability doesn't compromise capability, as the plant's total motor power of 550 kW provides ample crushing force, requiring an 850 kVA electric generator when operating in diesel-electric mode. The optional generator can be adapted directly to the plant chassis for sites without grid power access.
The feeding height of 6.3 meters accommodates most wheel loaders and excavators commonly used in quarrying and demolition applications, streamlining material handling operations. The plant's versatility extends to various applications, from quarry operations producing construction aggregates to demolition waste recycling and mining operations. The ability to process materials of varying hardness levels while maintaining consistent output quality makes the JS-3 suitable for contractors and operators who handle diverse projects.
Premium component selection throughout the JS-3 reflects CONSTMACH's commitment to durability and long-term performance. The combination of robust mechanical design with advanced control systems results in a mobile crushing plant that balances productivity with reliability. Regular maintenance is simplified through accessible service points, and the quality of construction translates to extended operational life even in demanding conditions. This mobile crusher plant represents a practical solution for operators who need flexible, high-capacity crushing capabilities without sacrificing the output quality required for premium aggregate markets.
