When crushing operations demand both power and precision, especially with hard materials like granite and basalt, the equipment choice becomes critical. CONSTMACH's JCV-1 addresses this challenge by integrating three specialized crushing stages into a mobile solution that delivers consistently high-quality output without compromising on efficiency.
This triple-chassis configuration represents a strategic combination of the proven JC-1 mobile crushing plant and V-70 mobile sand making plant technologies. The result is a system engineered specifically for operators who need to process extremely hard rock while simultaneously producing fine material with excellent cubical characteristics. The engineering behind this mobile crusher goes beyond simple assembly—it reflects years of refinement in design, material selection, and manufacturing precision.
The first chassis houses the primary crushing stage, built around the CJC-60 jaw crusher. This unit handles incoming material up to 610 x 380 mm, processing it through a vibrating feeder that ensures consistent flow. What sets this stage apart is the integrated bypass conveyor system, which removes soil and unwanted material before it reaches the crusher chamber. The feeding conveyor then transfers crushed material directly to the second stage, while hydraulic legs provide rock-solid stability during operation. A dust removal system keeps the work environment clean, and the PLC-based automation allows remote operation through a tablet interface.
The second chassis centers on a Metso HP 100 cone crusher, though equivalent models can be specified based on project requirements. This stage refines the material from the jaw crusher, with a two-deck vibrating screen classifying the output. Material that needs further reduction cycles back through a feedback conveyor to the cone crusher, ensuring optimal sizing. The fold-up stockpile conveyors make material handling straightforward, while another feeding conveyor moves appropriately sized material to the third chassis. Like the first stage, this chassis operates on hydraulic legs and includes comprehensive dust suppression. Operators can opt for an integrated diesel generator set if grid power isn't available at the site.
The third chassis completes the process with a VSI 100 CR closed rotor vertical shaft impact crusher. This is where the mobile crushing plant truly distinguishes itself—the vertical shaft technology produces material with superior shape characteristics, critical for applications where particle geometry matters. A three-deck vibrating screen provides precise classification, with oversized material returning via feedback conveyor for additional processing. The multiple stockpile conveyors allow simultaneous collection of up to five different product fractions, each meeting specific gradation requirements.
Production rates range from 60 to 80 tons per hour, though actual throughput depends on material hardness and desired output specifications. The VSI-700-CR model employed in the third stage delivers the fine material quality that many applications demand, particularly in concrete production and asphalt manufacturing where aggregate shape directly impacts final product performance.
The automation system deserves particular attention. Built around Siemens and Schneider components, the PLC control architecture manages all three chassis from a single tablet controller. Operators can monitor performance parameters, adjust settings, and troubleshoot issues without climbing onto equipment or accessing multiple control panels. This isn't just convenient—it's a fundamental safety and efficiency improvement over older mobile crusher designs.
Mobility defines this system's practical advantage. Each chassis dimensions comply with international road transport regulations, meaning the entire plant relocates between job sites without special permits or route planning. The first chassis measures 10 meters long by 3.1 meters wide by 4.4 meters high. The second and third chassis are identical at 17 meters long, 3.8 meters wide, and 4.4 meters high. Combined weight reaches 90,000 kg across all three units, but the wheeled chassis design with hydraulic legs makes positioning straightforward.
Setup time matters in mobile crushing operations, and the JCV-1 addresses this through intelligent design choices. The hydraulic opening mechanisms on the feeding hopper and stock conveyors mean operators can deploy the plant without external equipment like cranes or loaders. This self-sufficiency reduces mobilization costs and gets the plant producing faster—often within hours of arrival on site.
Power requirements are substantial but manageable. Total motor power reaches 370 kW, requiring a 750 kVA generator if operating off-grid. Many operations find that existing site power can handle the load, but the option to integrate a generator set provides operational flexibility in remote locations.
The combination of jaw, cone, and vertical impact crushing in a mobile platform creates production capabilities that previously required fixed installations. Operators get primary reduction, secondary refinement, and tertiary shaping in one coordinated system. The five simultaneous product fractions provide immediate sortation, reducing rehandling and allowing direct loading for different applications.
Material quality from this mobile crushing plant consistently meets demanding specifications. The closed rotor design in the VSI stage controls particle shape while the multiple screening stages ensure tight size distribution. For applications where aggregate quality determines project success, these characteristics translate directly to performance and profitability.
CONSTMACH built the JCV-1 for sustained operation under demanding conditions. Component selection emphasizes durability and maintainability, recognizing that downtime in mobile crushing operations affects entire project schedules. The dust removal systems across all three chassis protect both equipment and operators, extending service life while maintaining site environmental standards.
The JCV-1 triple chassis mobile crushing plant serves operations that won't compromise on output quality or operational flexibility. It processes the hardest materials while delivering the fine gradations and particle shapes that modern construction demands, all within a mobile package that relocates as projects require.
