Sand making and washing equipment on construction site

A large amount of stone and construction waste are often produced during the construction of large-scale projects, such as tunnel excavation and construction of hydraulic facilities. The mobile sand-making production line can be used to produce sand and gravel on the spot to reduce engineering costs.

The Xijin Water Control Project is located in the middle and upper reaches of the main stream of the Yujiang River in Hengxian County, Guangxi.

The total amount of engineering concrete is 882,200 m³, and a total of about 1,940,900 t of concrete aggregates are required, including about 1,358,600 t of coarse aggregate, about 582,300 t of fine aggregate, equivalent to about 960,000 m³ of gross material; graded crushed stone anti-filter material It is 136,900 m³, equivalent to about 150,000 m³ of wool.

The designed processing capacity of the sand and gravel processing system is 600t/h, which belongs to the large-scale sand and gravel processing system. This article shares the layout and process flow of the sand and gravel processing system of the project.

The sand and gravel processing system is mainly composed of the raw material preparation yard, the coarse crushing workshop, the pre-screening workshop, the middle crushing workshop, the screening workshop, the fine crushing workshop, the sand making workshop, the inspection and screening workshop, the finished aggregate silo, the finished sand silo, and the semi-finished product adjustment. It consists of silo, screening and adjusting silo, water treatment system, belt conveyor and power supply system.

Belt conveyors are used to connect and convey between each link in the processing process. The sand and gravel processing system is designed according to the technical process of three-stage crushing (coarse crushing open circuit, medium crushing open circuit and fine crushing closed circuit) and four-stage screening (80mm, 40mm, 20mm and 5mm).
