In Ethiopia, jaw crushers are commonly used in mining, construction, and aggregate production industries. The types of jaw crushers available depend on their design, motion characteristics, and application. Here are the main types of jaw crushers used or potentially used in Ethiopia:
1. Blake Jaw Crusher (Double Toggle Jaw Crusher)
– Mechanism: Uses a pivoted swing jaw with two toggle plates.
– Advantages: Stronger crushing force, suitable for hard and abrasive materials.
– Applications: Mining operations (e.g., gold, tantalum), quarrying for basalt and granite.
2. Dodge Jaw Crusher (Single Toggle Jaw Crusher)
– Mechanism: Has a simpler design with only one toggle plate and a fixed jaw at the bottom.
– Advantages: Lower maintenance costs but less efficient for hard rocks.
– Applications: Smaller-scale crushing operations in Ethiopia.
3. Universal Jaw Crusher (Hybrid Design)
– Mechanism: Combines features of both Blake and Dodge crushers for versatility.
– Advantages: Adjustable discharge opening for varied output sizes.
– Applications: Medium-sized crushing plants in Ethiopia’s construction sector.
4. Overhead Eccentric Jaw Crusher (Modern Single Toggle Design)
– Mechanism: Uses an eccentric shaft located above the chamber for efficient crushing motion.
– Advantages: Higher efficiency, better capacity, and lower energy consumption.
– Applications: Large-scale mining projects (e.g., cement production plants).
5. Mobile Jaw Crushers
– Mechanism: Mounted on tracks or wheels for portability.
– Advantages: Ideal for remote sites or temporary projects like road construction in Ethiopia.
