A portable rock crusher is a versatile machine designed to process aggregates on-site, reducing transportation costs and improving efficiency in mining, construction, and recycling projects. Its modular design integrates crushing, screening, and conveying components into a single mobile unit.
1. Feeder: A vibrating grizzly feeder pre-sorts material, removing fines and directing larger rocks to the crusher.
2. Crusher: Jaw or impact crushers are common choices. For example, a jaw crusher might feature a 30″ x 42″ feed opening and a capacity of 200–500 TPH.
3. Screen: A multi-deck screen (e.g., 5′ x 16′) classifies crushed material into different sizes (e.g., 0–5mm, 5–20mm).
4. Conveyors: Radial stackers or folding conveyors transport sorted aggregates to stockpiles.
| Model | Crusher Type | Max Feed Size | Capacity (TPH) | Power (kW) |
|—————–|——————|——————-|——————–|—————-|
| PRC-100 | Jaw | 24″ | 150–300 | 110 |
| PRC-200 | Impact | 30″ | 250–500 | 200 |
Q: What’s the advantage of a portable crusher over stationary plants?
A: Portability reduces hauling costs and enables on-site processing in remote locations.
Q: How to maintain a portable crusher?
A: Regularly check wear parts (e.g., jaw plates), lubricate bearings, and clean dust from screens.
A quarry in Texas deployed a PRC-200 unit to process limestone, achieving 450 TPH output with <5% oversize material. The setup reduced trucking distances by 60%, cutting operational costs by 30%.
Portable rock crushers are ideal for dynamic projects requiring flexibility and high productivity. Proper selection and maintenance ensure long-term ROI.
