1. Conveying: The vibrating feeder can pre-screen the materials while conveying them, so as to screen out the foreign substances in them to avoid damaging the working parts in the crushing cavity;
2. Coarse crushing: The working principle of jaw crusher is simple and reasonable. It imitates the chewing action of animals' jaws, and squeezes and crushes the raw materials of machine-made sand between the jaws, with high working efficiency;
3. Secondary crushing: impact crusher or cone crusher can be adopted according to the material properties. Impact crusher is suitable for crushing medium hardness materials with compressive strength as high as 350 MPa, and cone crusher is suitable for materials with medium hardness and above, with built-in spring overload protection system and various types. The new model is equipped with hydraulic protection device, which is suitable for medium crushing, fine crushing and ultra-fine crushing.
4. Screening: the screening step of vibrating screen can check whether each processing step of sand production line is qualified, and vibrating screen is an important guarantee to improve the production qualification rate;
5. Sand making: This step of sand making machine is equivalent to the soul of machine-made sand production line, and the performance of sand making machine directly affects the quality and output of machine-made sand. The common types of sand making machines are HVI sand making machine, VSI sand making machine and mobile sand making machine.
6. Cleanliness: The sand washer can effectively improve the quality of sand and gravel. The commonly used types of sand washers are wheel bucket sand washer, spiral sand washer and three-in-one sand washer, which have high cleaning degree, low failure rate, less sand output and large output.
The equipment configuration of machine-made sand production line is introduced above. In recent years, the infrastructure construction such as roads, railways, buildings and bridges is in full swing, and the exploitation of natural sand is restricted. Machine-made sand has gradually replaced natural sand in sand aggregate, and machine-made sand production line has gradually become the investment direction of investors.
