Most of the rocks refer to the mountain stones that have experienced wind and rain in the open air all year round, and they are very good materials for crushing and making sand. Because most of the sections of railway or highway construction are built according to the mountain, the mining and sand production of mountain stones is particularly important. Using local materials avoids all kinds of inconvenience caused by long-distance transportation.
The sand production process of mountain stone is roughly the same as that of general lump ore, which is connected by belt conveyor through the process of coarse crushing, fine crushing, sand making, screening, sand washing and finished products. Equipment for mountain stone crushing and sand making: a combination of jaw crusher and impact crusher for hard and large grain size rocks. The smaller or softer rocks use the combination of jaw crusher and cone crusher, and the jaw crusher and mountain stone sand making machine can also be used for direct sand making. Which kind of equipment to use depends on three factors: the feed particle size, hardness and the particle size of finished product. Which type of equipment you use depends on the output you require per hour. If you have high quality sand requirements, you can add a sand washing machine at the end to clean the sand. The finished grain size of the mountain stone sand making machine is controllable and adjustable, and the general particle size of finished product is 0-5mm, 5-10mm, and 10-20mm. If you need more sand and gravel specifications, you can choose different vibrating screening equipment, because the finished product specifications are determined by the specifications and layers of vibrating screen.
Mountain stone is a very good raw material for the production of sand and gravel, because it is open-air, so the mining of weathered rock is more convenient. The aggregate after mountain stone crushing and sand making is widely used in water conservancy and hydropower, high-grade highway, highway, high-speed railway, passenger dedicated line, bridge, airport runway, municipal engineering, high-rise building machine-made sand production and stone shaping in the engineering field.
