Portable rock crushing machines are essential for on-site crushing in construction, mining, quarrying, and recycling operations. These machines allow for mobility and flexibility, reducing the need for transporting materials to a fixed plant. Here are some common types of portable rock crushing equipment:
1. Portable Jaw Crushers
– Function: Primary crushing of hard rock (granite, basalt, etc.).
– Features:
– Adjustable jaws for different output sizes.
– Diesel or electric power options.
– Track-mounted or wheeled configurations.
– Examples:
– Metso Lokotrack LT106
– Sandvik QJ341
– Terex Finlay J-1175
2. Portable Cone Crushers
– Function: Secondary or tertiary crushing (producing finer aggregates).
– Features:
– High efficiency for medium-hard to hard rocks.
– Often used in aggregate production.
– Examples:
– Nordberg HP300 (Metso)
– Terex Cedarapids MVP450X
– McCloskey C44
3. Portable Impact Crushers
– Function: Versatile crushing for softer rocks (limestone, asphalt, concrete recycling).
– Features:
– High reduction ratio.
– Can produce cubical-shaped aggregates.
– Examples:
– Kleemann MR 110 Zi EVO2
– Rubble Master RM120X
– Eagle Crusher UltraMax 1400-45
4. Portable Screening Plants
*(Often paired with crushers)*
– Separate crushed materials into different sizes.
*Examples*:
– McCloskey S190
– Terex Finlay 883+
5. Combination Units (Crusher + Screen)
– Some models integrate a crusher and screen in one unit (e.g., Metso Lokotrack LT220D).
6. Portable Rock Hammermills
*(For smaller-scale operations)*
– Used in mining & demolition applications.
– Example: Stedman Machine’s portable hammer mill.
