1200 tons of limestone crushing and sand production line per hour

A 1200 tons per hour (tph) limestone crushing and sand production line is a large-scale operation that requires several types of equipment to work together to achieve the desired output. The equipment required for this capacity may include:

1. Primary crushing equipment: A jaw crusher or a crawler-type hydraulic jaw crusher can be used to crush large stones into smaller ones. Depending on the stone's hardness, a capacity of around 600-900 tph can be achieved.

2. Secondary crushing equipment: A cone crusher or an impact crusher is typically used to further crush the material to a smaller size. A 1200 tph capacity can be reached with the right machine and configuration.

3. Tertiary crushing equipment (optional): If a finer product is required, such as sand, a VSI crusher or a vertical roller mill can be added to the line. This step may reduce the overall capacity to around 600-900 tph, depending on the machine's specifications.

4. Screening equipment: To separate the crushed limestone into different size fractions, such as sand, gravel, and coarse aggregates, a series of vibrating screens or trommel screens should be used. The number and size of screens required will depend on the desired output size range.

5. Washing equipment (optional): If the final product requires a high level of cleanliness, a washing station can be added to remove dust and impurities. This step may also reduce the overall capacity slightly.

6. Conveyor belts: Conveyor belts are necessary to transport the raw material and the crushed products between the different stages of the production line.

To achieve a 1200 tph capacity, it's crucial to optimize the configuration of the equipment, ensure proper maintenance, and consider factors such as the stone's hardness and the desired output size. It's also important to note that the actual production rate may vary depending on factors such as the raw material's properties and the efficiency of the operation.
