Taking the sand and gravel aggregate production line as an example, the front end of the production line adopts jaw crusher, screening, cone crusher, sand making machine, and finished product screening. Common device configuration schemes are as follows:\r\n\r\n1.Coarse crushing feeding equipment\r\n\r\nThere are mainly two types of coarse crushing feeding equipment: bar feeder and heavy plate feeder. The bar feeder can also achieve preliminary screening and remove some impurities such as soil.
2.Coarse crushing equipment\r\n\r\nIn the production of sand and gravel aggregate, jaw crusher is a common coarse crushing equipment, which crushes larger materials into medium-sized materials, which is convenient for the next step of crushing.\r\n\r\n3.Intermediate crushing equipment\r\n\r\nThe medium crushing cone crusher and the pre-screen constitute a closed-circuit system, and the material <12mm can be directly used as the raw material of the machine-made sand without entering the crushing system.\r\n\r\n4.Shaping sand making equipment\r\n\r\nThe third stage of crushing adopts a vertical shaft crusher, which has the dual functions of crushing and shaping. After the material is crushed and shaped by the vertical shaft crusher, it is fed into the finished product screen, and the finished product screen and the vertical shaft crusher form a closed circuit system.\r\n\r\n5.Finished product screening equipment\r\n\r\nA flap valve is installed at the hopper of the finished product screening, which can return a part of the finished aggregate to the vertical shaft crusher for re-crushing, so as to adjust the output ratio of the final product and make the system control more flexible.\r\n\r\nWhether it is hard rock crushing or soft rock crushing, mobile crushing production or stationary crushing production, we can provide you with the most suitable production equipment
