Granite crushing production line process
The granite crushing production line process mainly involves the following steps:
1. **Primary Crushing:**
- The raw granite is first transported to the primary crusher (usually a jaw crusher) for initial crushing.
- The crushed granite is then conveyed to a secondary crusher (cone crusher or impact crusher) for further reduction.
2. **Secondary Crushing:**
- The secondary crusher reduces the size of the granite fragments further.
- After the secondary crushing, the material is passed through a screen to separate the fines and dust from the crushed granite.
3. **Screening:**
- The separated fines and dust are transported to a separate processing plant for further treatment, such as making concrete or asphalt.
- The crushed granite that passes through the screen is then transported to a stockpile for further processing or to be sold as is.
4. **Tertiary Crushing (Optional):**
- If a finer granite product is required, the crushed granite can be passed through a tertiary crusher (usually a cone crusher or a vertical shaft impact crusher).
- The tertiary crusher reduces the size of the granite even further, producing a range of sizes from fines to large aggregate.
5. **Screening and Separation:**
- After the tertiary crushing, the granite is passed through a series of screens to separate it into different size fractions.
- The separated fractions are then transported to their respective stockpiles for further processing or use in various construction projects.
6. **Washing and Dewatering (Optional):**
- If necessary, the crushed granite can be washed to remove dust and other impurities.
- A dewatering screen is used to remove excess moisture from the washed granite, resulting in a cleaner and dryer final product.
7. **Stockpiling:**
- The final crushed granite products are transported to their respective stockpiles, where they are stored until they are needed for use in construction projects or for further processing.
This is a general outline of the granite crushing production line process. The actual process may vary depending on the specific requirements of the project and the type of granite being processed.
