This project is a sand and gravel processing plant project of the third phase of a comprehensive building materials resource service project in Mongolia. It is planned to build a new 300t/h river pebble crushing sand production line. The raw materials are riverbed sand pebbles, foundation pit sand pebbles and other mixtures. The soil content is high. After crushing treatment, the mixture can be directly sieved and shaped. It can be divided into three types: 0~5mm, 5~20mm, and 20~40mm. Those larger than 40mm are broken and processed into one type of 16~31.5mm, with a total of four finished materials.
