As one of the main raw materials of Guangdong sand and gravel mines, granite has excellent characteristics of machine-made sand and gravel raw materials due to its high hardness. However, the high hardness of granite also brings great wear and tear to the equipment, so it is important to choose the right equipment during the machining process. It is recommended to adopt the four-stage crushing mode of "jaw crusher + single-cylinder hydraulic cone crusher + multi-cylinder hydraulic cone crusher + vertical shaft impact crusher" to share the crushing pressure of each section, ensure the output of the production line, and reduce the later operation and maintenance costs.
First of all, the jaw crusher is responsible for the coarse crushing work throughout the production line. It is capable of crushing large granite stones into medium-sized particles (discharge size around 5-30 cm).
Next, the use of cone crushers includes both a single cylinder and a combination of multiple cylinders. This combination can share crushing and wear pressure, improve crushing efficiency and production, and is ideal for medium to large hard rock crushing projects.
In addition to jaw and cone crushers, VSI crushers are equally important. On the one hand, it can be used for stone shaping, removing the sharp corners of the broken stone, making the grain shape more rounded, and meeting the high-standard stone standards required for key projects such as high-grade highways and railways. On the other hand, impact crushers play a key role in the production of manufactured sand, further crushing stones, stone powder and leftovers into manufactured sand less than 5mm, meeting the needs of both crushed stone and manufactured sand.
Of course, a complete granite sand and gravel aggregate production line also needs to include supporting equipment such as vibrating feeders, circular vibrating screens, belt conveyors, etc., to complete the functions of conveying raw materials and screening of finished products. These supporting equipment work together to ensure the efficient operation of the entire production line.
When choosing granite processing equipment, we should not only consider production efficiency, but also pay attention to quality and cost control. Reasonable configuration of equipment, in the crushing, shaping and machine-made sand production and other links to give full play to the characteristics and advantages of various equipment, can improve processing efficiency, ensure product quality, and reduce follow-up maintenance costs.
In conclusion, the selection of the right equipment is essential to improve the efficiency and quality of granite processing. Through the four-stage crushing mode of "jaw crusher + single-cylinder hydraulic cone crusher + multi-cylinder hydraulic cone crusher + vertical shaft impact crusher", the pressure can be shared, the output can be increased, and the later operation and maintenance costs can be reduced. At the same time, it is equipped with vibrating feeder, circular vibrating screen, belt conveyor and other supporting equipment, which can achieve comprehensive production line operation and improve the overall efficiency. Choosing the right equipment will drive the quality and efficiency of granite raw material processing to new heights!
