120 TPH Sand Washing Plant Process

Process flow of 120 tons of machine-made sand production line per hour:
1. Feeding: The material is uniformly fed into a section of coarse crushing equipment through a vibrating feeder;
2. Coarse crushing: The first stage coarse crushing jaw crusher performs primary coarse crushing on the material, and after crushing, it is transported to the second stage intermediate crushing through a conveyor belt;
3. Medium crushing: The two-stage impact crusher has a large feeding port and can accept various types of coarse crushing materials. There are two options here, but when your sand making raw materials have a harder hardness, you can choose a cone crusher, which has stronger hydraulic crushing force; If it is a medium to low hardness material, a impact crusher can be selected. After one treatment, when the discharge reaches 55mm or less, it can enter the fine crushing treatment. During this process, a portion of 5-10mm and 10-20mm finished products will be screened out, and other materials will enter the fine crushing sand making process;
4. Fine sand: When the crushed materials in the second stage are transferred to the fine sand making machine for sand making, finished products between 0-5mm are produced. If they do not meet the size requirements, they will form a closed loop and return to crushing again;
5. Sand washing: After screening out the 0-5mm material, it flows directly into the sand washing machine for cleaning. The wheel bucket sand washing machine has a cleanliness of up to 99% and can wash out the steam drum and dust on the machine sand.
