Advantages of dry sand making
After dry sand making uses a powder separator to remove the mud powder in the artificial sand, the sieve can fully meet the standards of construction sand, and the stone powder content in the artificial sand can also be controlled by the powder separator within the range specified by the state. Effectively improve the compressive strength of concrete and the workability of concrete. Dry sand making is more conducive to environmental protection.
The role of vibrating screen in sand and gravel production process
The dry sand making process is based on the traditional wet sand making process. The dry sand making process mainly uses equipment such as hoppers, vibrating feeders, impact sand making machines, vibrating screens, elevators, and high-efficiency powder separators. Vibrating screens play a role in screening materials with different particle sizes in the process.
The principle of vibrating screen screening
The
vibrating screen has a complete set of equipment working and operating system. A vibrating motor is installed at the bottom of the vibrating screen. The unbalanced weights installed at the upper and lower ends of the vibrating motor convert the motion of the motor into three- dimensional motion of horizontal, vertical and inclined, and then This movement is transmitted to the screen surface to achieve the purpose of screening. In addition, for different grades of screening, the moving direction of the material can be changed by changing the phase angle of The upper and lower weights of the motor. The angle of the center of gravity is different, and the screening accuracy of the material is different.
