The construction, mining and aggregate industries rely on efficient crushing operations to process raw materials into various commercially valuable end products. A critical step in these bulk material processing applications is the sizing reduction of oversized rocks and demolition debris through mechanical crushing.
Traditionally, this has been performed by stationary crushing plants, which require hauling of unconsolidated materials over long distances. This centralized approach results in issues like high transportation costs and wasted time. With the increased adoption of mobile crushers, on-site crushing capabilities are revolutionizing how these industries optimize their material handling logistics and throughput. This article provides an overview of the different types of mobile crushers available and examines their applications in construction and demolition waste recycling as well as mining operations.
Sure, here are some more details on the main types of mobile crusher:
- Jaw Crushers: Ideal for primary crushing of medium-hard materials. They have a fixed and moving jaw to compress and crush rocks into smaller sizes for subsequent processing. Commonly used in C&D recycling and mining applications.
- Impact Crushers: Suitable for soft to medium-hard materials and recyclables with low abrasiveness. They use rapid impact blows from hammers or blow bars to break rocks against a surface for size reduction. Good for mixed debris.
- Cone Crushers: Excellently suited for secondary and tertiary crushing after a jaw crusher for high efficiency. Their oscillating cones crush material via compression between a movable cone and fixed bowl liners. Ideal for hard rocks and minerals.
- Vertical Shaft Impact (VSI) Crushers: Advanced machines that use a high-speed rotating rotor with wear resistant tips to pulverize material through impact against an abrasive anvil. Create highly cubical shaped sands for concrete/asphalt making.
- Hammer Crushers: Heavily used in C&D recycling for their ability to efficiently crush concrete, asphalt and rubble. Feature multiple hammers that pulverize feeds against grinding plates or anvils to desired sizes.
- Multi-terrain chassis options allow mobility on roads, job sites and even across difficult terrain like mine haul roads. Common platforms include wheel, track (track-mounted) and compact modular types.
Proper feed material characterization helps decide the best primary, secondary and tertiary crushing combinations within mobile, semi-mobile or stationary crushing circuits.
