Basalt is a volcanic rock that is commonly used in construction as a building material. It is a dense, dark-colored rock that is formed from the solidification of lava. Basalt crushing and screening plants are used to process this rock into various sizes and shapes for different construction applications. In this article, we will discuss the process of basalt crushing and screening plant.
Basalt Crushing:
The first step in the process of basalt crushing is to blast the rock in a quarry. The blasted rock is then transported to a crushing plant where it is crushed into various sizes. The crushing process involves several stages, including primary crushing, secondary crushing, and tertiary crushing.
Primary crushing is usually carried out with a jaw crusher or gyratory crusher. The crushed rock is then screened to separate the larger pieces from the smaller ones. The larger pieces are sent back to the crusher for further crushing.
Secondary crushing is carried out with a cone crusher or impact crusher. The crushed rock is again screened to separate the larger pieces from the smaller ones. The smaller pieces are then used as construction material.
Tertiary crushing is carried out with a vertical shaft impact crusher (VSI). The VSI crusher uses a rock-on-rock crushing principle to break the rock. The crushed rock is then screened to separate the larger pieces from the smaller ones.
Basalt Screening:
After the crushing process, the basalt rock is screened to separate the various sizes of rock. The screening process involves several stages, including primary screening, secondary screening, and tertiary screening.
Primary screening is carried out using a vibrating grizzly feeder. The feeder separates the larger pieces from the smaller ones and sends them to the crusher for further crushing.
Secondary screening is carried out using a vibrating screen. The screen separates the smaller pieces from the larger ones and sends them to the appropriate storage area.
Tertiary screening is carried out using a finishing screen. The finishing screen separates the fine particles from the larger ones and sends them to the appropriate storage area.
Basalt Plant Equipment:
The equipment used in a basalt crushing and screening plant includes a primary crusher, secondary crusher, tertiary crusher, vibrating grizzly feeder, vibrating screen, and finishing screen. Depending on the application, additional equipment such as conveyors, washing equipment, and storage bins may be required.
In conclusion, basalt crushing and screening plants are used to process basalt rock into various sizes and shapes for construction applications. The process involves several stages of crushing and screening, and requires the use of specialized equipment such as crushers, screens, and feeders. With proper planning and implementation, basalt crushing and screening plants can produce high-quality construction materials that meet the needs of various industries.
