Basalt is an igneous rock widely used in various fields due to its hardness, durability, and specific mineral composition, including road construction, building materials, decoration, hydraulic engineering, and railway projects.

The process of crushing and screening basalt into materials for road construction typically involves the following steps:

Crushing Process: Firstly, raw basalt is collected from the collection site and transported to the processing site. At the processing site, primary crushing equipment like jaw crushers is used to break down large pieces of basalt into smaller chunks. Depending on the required particle size and specifications, secondary crushing equipment such as cone crushers or impact crushers may be used to further crush the primary crushed stones.

Screening Process: After crushing, vibrating screens or other screening equipment are employed to separate the crushed stones into different particle sizes as per the desired requirements. Sometimes, the stones need to be washed to remove dust, mud, or other impurities. Processed basalt aggregates are typically stored in storage warehouses or stockpile areas for future road construction projects, and they are categorized and stored based on their specifications and sizes.

When choosing basalt crushing and screening equipment, factors such as project requirements, the hardness and size of the original basalt, and the desired final product specifications need to be considered. Common equipment includes primary crushing equipment (such as jaw crushers), secondary crushing equipment (such as cone crushers or impact crushers), vibrating screens, washing equipment, conveyors, and feeders. Equipment selection should be carried out by professional engineers based on specific project needs, taking into account production capacity, operational costs, equipment availability, and maintenance requirements, among other factors.
