Sand and gravel aggregate production process

Sand and gravel aggregate production process mainly contains: feeding, coarse crushing, medium crushing, fine crushing, transmission, if you want to improve the quality of finished sand and gravel aggregate, in addition to the high demand for equipment, you can choose to increase the sand washer, effectively improve the quality of finished aggregate, a full set of sand and gravel aggregate production process is as follows:

1. Feeding: firstly, the raw materials will be put into the vibrating feeder by the raw material warehouse, and the vibrating feeder will be evenly transferred to the jaw crusher for coarse crushing;

2. Coarse crushing: Jaw crusher as a section of coarse crushing, the feed opening is large, up to 1200mm or less, the material will be evenly crushed to reach the second section of the crushing feed size, Jaw crusher tiger crushes, strong, small energy consumption, high yield;

3.Medium crushing: two sections of medium crushing can choose impact crusher or cone crusher, according to the choice of materials, low and medium hardness materials choose impact crusher, high hardness materials choose cone crusher, impact crusher will be processed into the material below 55mm, if it does not meet the requirements of the three sections of sand, need to return to the re-crushing until it meets the requirements, not only to help the production of sand making equipment, and It not only helps the production of sand making equipment, but also causes less damage to the equipment.

4. Fine crushing: three-stage sand making is the main link, sand making machine feed below 55mm, the finished product can be up to 0-5mm, mainly used for the production of high-quality sand and gravel aggregates, the output particle size uniformity, grading continuity, rounded grain shape, in line with the quality of sand and gravel and testing.

5. Screening: the end is the screening process, vibrating screen machine is also more important, screening speed determines the production efficiency, using vibrating screen machine with strong excitation force, not only will not appear blocking phenomenon, in screening different specifications of materials, particle shape more uniform.

6. Sand washing: If the requirements for wet production, you can increase the sand washing machine, bucket wheel sand washing machine to clean the finished product, the construction of a water reservoir, to achieve water recycling.
