WHAT IS THE PROCESS OF QUARRYING?
Minerals have to be quarried where they occur. More often than not, these minerals occur in attractive upland or river valley contexts. The industrial nature of mineral extraction means that there is a tendency to conflict with the surrounding landscape and population unless the quarrying, processing and transportation is carefully planned and executed. Aggregate can be obtained from crushed hard rock, from sand and gravel deposits, from marine deposits and from recycled building materials.
Sand Quarry Processing Machine
The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction. Gyratory crushers, sand making machine, jaw crushers, and impact crushers are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification. At some plants, after initial crushing and screening, a portion of the sand may be diverted to construction sand use.
What is the Process of Quarrying?
According to the specific production conditions, our quarry plant can be divided into large sized ,medium sized and small sized quarry plant. To most of our clients, our medium sized quarry plant is more suitable for mining and construction production line. Meanwhile, our high quality and low cost of medium sizes quarry plant has helped clients make much more money.
The quarry plant involves the following processes: mining, processing, crushing, screening and transportation. Mining methods involve removing the overburden to extract the underlying rock deposits. The shot-rock is typically transported to the crushing plants using trucks. The large end users in the crushing plant consist of feeders, crushers, conveyors and screens. Crushers mechanically break the stone into smaller pieces. Reduction in size is generally accomplished in several crushing stages, as there are practical limitations on the ratio of size reduction through a single stage. Crusher selection is based on rock type, required size reduction, output rock shape and production rate. Truck transportation within and outside of the quarry is the most common method of stone transportation. Then the whole medium sized quarry plant is completed.
Sand Quarry Plant Manufacturer
As a professional construction sand and gravel crushing plant manufacturer, we can supply the production line with reliable performance, easy operation, high efficiency to the clients. In mining operations, the layout of crushing plants and auxiliary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.
