JS-1 Mobile Jaw and Secondary Impact Crusher Plant 60-80 TPH

CONSTMACH's JS-1 mobile crushing and screening plant represents a significant advancement in processing medium-hardness materials including limestone, riverstone, and dolomite. This dual-chassis configuration combines sophisticated engineering with practical mobility, delivering consistent performance across diverse jobsite conditions.

The JS-1 mobile crusher stands out through its integrated approach to material processing. The first chassis houses a feeding hopper equipped with a vibrating feeder that channels material directly into the CJC-60 primary jaw crusher. This initial crushing stage handles maximum feed sizes up to 600 x 380 mm, making it suitable for various quarrying applications. A by-pass conveyor allows operators to extract soil and fines before the crushing process begins, improving overall efficiency and reducing unnecessary wear on crushing components. The feeding conveyor maintains steady material flow, while hydraulic legs provide stable positioning on uneven terrain. All control functions are centralized through an integrated power and control panel mounted on the wheeled mobile chassis.

The second chassis features the CSI 1210 secondary impact crusher, which transforms primary crushed material into precisely sized aggregates. This mobile crushing plant incorporates a three-deck vibrating screen that separates material into distinct fractions. A feedback conveyor returns oversized material from the screen back to the secondary impact crusher's hopper, creating a closed-circuit system that maximizes product quality. Fold-up stockpile conveyors simplify transport and allow rapid deployment at new locations. Like the primary unit, this chassis includes hydraulic legs for stability, its own power and control panel, and a dust removal system that maintains cleaner operating conditions.

Production capacity ranges between 60 and 80 tonnes per hour, with variation depending on the hardness characteristics of the processed material. The secondary impact crusher's specialized design produces final aggregates with excellent cubical shape, a critical requirement for concrete production where particle geometry directly affects concrete strength and workability. Operators can simultaneously generate three or four different size fractions, providing flexibility to meet varied market demands without system reconfiguration.

The JS-1 mobile crusher plant operates through a sophisticated automation system built around premium SIEMENS and SCHNEIDER electronic components controlled by a programmable logic controller. The entire plant is managed through a tablet interface, giving operators intuitive control over all crushing and screening functions. This high-tech approach simplifies operation while providing real-time monitoring of system performance.

Transportation logistics receive careful attention in the JS-1's design. Both chassis conform to international road transport regulations, allowing the complete plant to move between jobsites using a single tractor. The first chassis measures 11 meters long by 3 meters wide by 4.4 meters high, while the second chassis extends 17.8 meters in length, 4.3 meters in width, and 3.35 meters in height. The feeding height of 4.5 meters accommodates standard loading equipment without requiring specialized machinery.

Rapid deployment capabilities make this mobile crushing plant particularly valuable for contractors working multiple sites or projects with tight schedules. The user-friendly design allows quick assembly, and operators can bring the plant online in minimal time. When equipped with optional hydraulic opening mechanisms for the feeding hopper and stock conveyors, the system becomes fully operational without external equipment such as cranes or loaders. This independence reduces mobilization costs and eliminates delays waiting for auxiliary machinery.

The complete system operates on 275 kW of total motor power, requiring a 550 kVA electric generator when grid power is unavailable. CONSTMACH offers an optional diesel-electric generator set that can be adapted directly to the plant's chassis, providing self-contained power generation for remote locations. The entire plant weighs approximately 60,000 kg, distributed across both chassis for balanced road transport.

Quality components and thoughtful engineering ensure the JS-1 delivers reliable performance over extended service periods. The combination of proven crushing technology, effective screening, and integrated material handling creates a comprehensive solution for aggregate production. Whether processing riverstone for construction aggregates or crushing limestone for industrial applications, the JS-1 mobile crusher provides the versatility and performance contractors need to meet demanding production schedules while maintaining product quality specifications.
