Material crushing is a key stage in industries such as mining, quarrying, recycling and construction. While all of them require reducing material size, each sector has its own specific requirements and working conditions—from material hardness to plant mobility.
ARJA, a benchmark manufacturer in crushing with 100% European technology, offers a range of mills and equipment tailored to each of these sectors. Below, we analyze the specific features of each application and the most suitable ARJA models for each case.
1. Mining Plants: Large-Scale vs. Small-Scale
Large-Scale Mining
Large-scale mining is typically focused on extracting valuable metals such as gold, copper, zinc or iron. These materials are usually embedded in extremely hard rocks and extracted in high volumes, requiring large, high-capacity machinery that is resistant and reliable for continuous operation.
These plants often run fully automated processes, including complete lines for primary, secondary and tertiary crushing. Energy and maintenance costs are critical factors, so efficient machines with durable wear parts are essential.
ARJA specializes in complementary and adjacent processes to the core activity of large-scale mining, offering efficient and robust crushing solutions for intermediate or support stages within the overall processing circuit.
Recommended ARJA Equipment:
- JCR-P Leo: Jaw crusher for the first reduction of very hard materials.
- ICR-P Geminis: Primary impact crusher as an alternative to jaw crushing, offering better cubical shape.
- ICR-S Tauro: Robust secondary impact crusher, ideal for high-volume ore processing.
Small-Scale Mining
Small-scale mining takes place in smaller sites, often in remote or hard-to-reach areas. In this case, equipment compactness, easy transportation and low energy consumption are priorities. Quick installation and simple maintenance are also key.
Recommended ARJA Equipment:
- ICR-S Tauro: Suitable for secondary stages, depending on required production.
- ICR-S Libra: Compact secondary impact crusher, low energy use and easy installation.
- FD-AVM: Mechanical vibrating feeder for steady flow in mobile plants.
2. Quarries: Aggregate and Natural Stone Extraction
Quarries focus on extracting materials like limestone, granite or basalt, mainly used in construction. These materials must be precisely crushed to achieve different grain sizes (sand, gravel, crushed stone) and cubical shape, essential for high-quality concrete or asphalt.
Crushing plants in quarries are usually fixed or semi-fixed, operating continuously. It is crucial to use wear-resistant machines capable of delivering a homogeneous product.
Recommended ARJA Equipment:
- JCR-P Leo: For primary rock crushing.
- ICR-S Tauro / Libra: For secondary stages, depending on production requirements.
- ICR-T Piscis: Tertiary crusher for sand or fine material production.
- SC-CVP: Screens for accurate material separation by size.
3. Recycling: Processing Construction and Demolition Waste (CDW)
CDW recycling is essential for the circular economy. It involves processing demolition materials (concrete, bricks, asphalt, wood, plastic) into reusable resources.
The wide variety of materials requires flexible crushing equipment, able to handle irregular impact loads and efficiently separate impurities and metals.
Recommended ARJA Equipment:
- ICR-S Libra / Tauro: Highly versatile with easy maintenance access.
- ICR-T Piscis: Excellent for refining recycled materials into reusable sand.
- SC-CV: Screens resistant to abrasive materials.
- FD-AVA: Feeders suitable for heterogeneous material flows.
4. Construction: Civil Works Materials
Construction is a cross-cutting sector that consumes materials from both quarries and recycling plants. It requires a steady supply of high-quality aggregates for structural concrete, base layers, subbases and drainage systems.
In this context, crushing equipment must offer low cost per ton, easy output adjustment, and operational reliability.
Recommended ARJA Equipment:
- ICR-S Libra: Fast adjustment for varying grain size needs.
- ICR-T Piscis: Ideal for sand production used in mortars or asphalt.
- SC-CVP: Screening system to classify aggregates according to UNE standards.
- FD-AVM: Constant dosing improves overall line efficiency.
Each industrial sector presents its own challenges. Thanks to its expertise and product range, ARJA offers complete, tailored solutions for each scenario. From high-demand mining operations to urban recycling, ARJA impact crushers optimize production, minimize wear and maximize return on investment.
