What type of crusher is commonly used in stone factories for a 300 ton gravel production line

In stone factories, the type of crusher commonly used for a 300 ton gravel production line can vary depending on the specific requirements of the project, such as the type of rock being processed and the desired output size. However, a combination of jaw crushers, cone crushers, and/or impact crushers is often used in gravel production lines.

For a 300 ton gravel production line, you might consider using the following equipment:

1. Primary crusher: A jaw crusher is typically used as the primary crusher in gravel production lines. It is suitable for crushing hard and abrasive materials, such as granite, basalt, and limestone. A popular model for this application might be a PE 750 x 1060 jaw crusher, which has a capacity of around 300-400 tons per hour (tph).

2. Secondary crusher: A cone crusher or impact crusher can be used as the secondary crusher to further process the material. For example, a HP 200 cone crusher or a VI 700 impact crusher could be suitable. These crushers have capacities ranging from 100-300 tph, depending on the specific model and configuration.

3. Screening equipment: After the primary and secondary crushing stages, screens are used to separate the crushed material into different particle sizes. You might need several screens with different mesh sizes, such as a 10-30 mm screen and a 30-60 mm screen. The required screening capacity will depend on the desired output size and production rate.

Please note that these are general recommendations, and the specific equipment chosen for your project should be based on your material properties, desired output size, and production capacity requirements. It's important to consult with a professional manufacturer or supplier to ensure that you choose the most suitable equipment for your needs.
