A stone crusher used for the production of tar stone (tarmac or asphalt) typically processes aggregates (crushed stone, gravel, or sand) that are mixed with bitumen to create asphalt. A stone separator (or aggregate separator) is often integrated into the crushing plant to ensure proper grading and remove unwanted materials.
Key Components for Tar Stone Production
1. Primary Crusher (Jaw Crusher/Gyratory Crusher)
– Breaks large rocks into smaller pieces (~6-8 inches).
2. Secondary Crusher (Cone Crusher/Impact Crusher)
– Further reduces stone size (~0.5-2 inches) suitable for asphalt mix..jpg)
3. Vibrating Screen & Stone Separator
– Separates crushed stones into different sizes (e.g., coarse, medium, fine).
– Removes dust and oversize material via sieving mechanisms.
4. Conveyor Belts
– Transports crushed stone between stages.
5. Storage Bins/Hoppers
– Stores graded aggregates before mixing with bitumen.
Types of Stone Separators
- Vibrating Screens: Separate stones by size using mesh screens.
- Air Separators: Remove lightweight debris (dust, organic matter).
- Magnetic Separators: Extract metal contaminants.
- Dewatering Screens: Remove excess moisture if needed.
- Use a multi-stage crushing system for uniform aggregate size.
- Ensure proper screening to meet asphalt mix specifications.
- Regular maintenance prevents clogging and wear in crushers & separators.
