As a professional stone production line manufacturer, our stone production line equipment includes Crusher (sand making machine), jaw crusher, impact crusher, vibrating screen, etc. According to different production we set, the production is usually 50-500 tons / h. It can also configure cone crusher or sand washer being based on the different materials. And they are applied to many kinds of aggregates and artificial sand making operation, such as granite crushing, river gravel sand making, silica crushing, and production of construction sand, basalt and limestone. The stone production line is applicable to hydroelectric power, high-speed, building materials, urban construction industry,etc.
Stone production line process
Having past storage bin, chunks of stone are sent to the jaw crusher by vibrating feeder for primary crushing. After coarse crushing, the stone is sent to impact crusher through belt conveyor for further crushing. And then the broken stone through conveyor again onto vibrating screen for separating. The processed stones are of several different specifications, and which meet the size requirements is sent to the finished pile. Those don’t meet the size requirements will send back to impact crusher for crushing again, thus forming a closed circuit recycled many times. Tertiary rusher has a reasonable price. Therefore, it often used as tertiary equipment and replaced impact crusher and sand making machine in stone production line.
Ecosystems are affected by the physical perturbations of mining operations, as well as the chemical alterations in soil and water. Mining activities vary, but can include soil compaction and conversely, removal of the topsoil. These alterations disrupt nutrient dynamics by minimizing the availability of nitrogen and phosphorus, lower the pH through the acidification of the soil and can introduce toxic metals and acids. Depending on the scale and nature of the mining operation, these effects can be localized to the location of the mining or, through local hydrology, can extend to nearby aquatic systems, such as stream, wetlands and lakes. All mining activities create considerable waste, including acid runoff and chemical byproducts of refining. Coal mines are particularly prone to acid runoff.
