Sand production line
[China Aluminium Network] Sand aggregate production system is a production enterprise that mines and processes concrete coarse and fine aggregates, including the material collection site, aggregate processing plant, stockyard, and internal transportation system. Its task is to supply the quality, quantity, and cost-effective coarse and fine aggregate required for concrete mixing in a timely manner.

The design content of the aggregate production system mainly includes exploration and selecting stockyards. Determine the source, mining and transportation methods; select the location of the aggregate processing plant, determine its production capacity and sand production line process flow; carry out aggregate storage design and quality control.
The role of the aggregate stockyard is to store a certain amount of sand and gravel to solve the imbalance between orthopedic production and demand. Aggregate stocks are divided into three categories: wool stockpiling, semi-finished product stockpiling and finished product stockpiling. Wool piles exist to solve the imbalance between the production and processing of aggregates; semi-finished materials (pre-screened sand and gravel mix) tower exists to solve the imbalance between the various processes of aggregate processing; finished product piles exist in the guarantee The requirements for the continuous production of concrete materials, and play a role in reducing and stabilizing the moisture content of the aggregate (instead of sand dewatering) and reducing or stabilizing the temperature of the aggregate.
The total reserves of gravel materials can generally be considered as 50% to 80% of the average monthly value during peak hours. During the stop period during the flood season and frozen period, the aggregate demand of the stop production and the 20% margin check must be used.
The capacity of finished product yards should still meet the natural dewatering requirements of gravel materials.
When the sand production line system design gravel material silo, the position and elevation of the silo should be selected above the flood level, there should be good drainage and sewage facilities around it, and water collection wells, drains and washing belts should be arranged in the underground gallery. Mud pipes. The structural design of the silo should meet the requirements of safety, economy, and convenient maintenance, minimize the number of aggregate transfer, and prevent deformation of the trestle and non-uniform subsidence of the gallery.
To prevent the crushing and separation of coarse aggregates, the drop height should be controlled below 3m, and the height difference at the belt joints should be controlled below 1.5m. When quasi-materials are used, they should be stratified and rise layer by layer. Pay attention to the dehydration of fine aggregates, and keep clean and certain humidity.
