The JC-3 Mobile Crushing Plant is a wheeled, two-chassis hard stone crushing and screening plant built around a CJC-110 Primary Jaw Crusher, a secondary cone crusher and a vibrating screen. The notes below summarise the materials it processes, the products it makes, its applications, and how it compares with other configurations.
What materials can the JC-3 process?
The plant is configured for hard, abrasive, high-silica rock and general aggregate feedstocks, including:
Granite
Basalt
Gabbro
River stone and river gravel
Other competent quarried hard stone
What products does it make?
As a closed-circuit jaw-cone-screen plant, the JC-3 produces sized aggregate. The multi-deck screen separates the crushed material so that three or four fractions can be produced simultaneously, while oversize is recirculated to the cone crusher for further reduction.
Which industries and applications use it?
High-volume aggregate production for concrete and asphalt
Major road, highway and infrastructure projects
Hard stone quarrying
Mining and mineral processing
Contractors needing large mobile crushing capacity at the working face
Mobile versus stationary: what is the trade-off?
The JC-3 delivers high capacity while remaining relocatable on hydraulic legs without foundations, which suits large but time-bound projects and quarries that reposition processing capacity. A stationary plant of equivalent capacity generally offers higher sustained output and more configuration flexibility but is fixed and requires significant civil works. The JC-3 balances high throughput with mobility.
What are the main wear parts and maintenance points?
Principal wear items are the jaw plates and cheek plates of the jaw crusher and the mantle and concave liners of the cone crusher, together with conveyor belts, screen media and feeder liners. Because the JC-3 is sized for very hard, high-silica rock such as granite and basalt, liner wear is significant and benefits from regular inspection and timely replacement.
How does it compare with alternative plants?
The JC series uses a cone crusher for the secondary stage, which is well matched to hard, abrasive feed and offers durable liner life at high tonnage. CONSTMACH's JCV plants add a vertical shaft impactor as a third stage for more cubical product, while mobile jaw-and-impact plants use an impact crusher instead of a cone and are generally directed at softer, lower-abrasion stone such as limestone.
How does it integrate into a complete plant?
The JC-3 runs as a self-contained two-stage closed-circuit unit, with feeder, jaw, cone, screen and conveyors mounted across two chassis. It can operate independently or feed downstream screening or washing equipment where finer classification or washed aggregate is needed.
