The dry sand screening machine can be divided into three types: linear vibration type, cylindrical type and swing type. Without special requirements, we are equipped with a linear vibration type screening machine in this production line. The screen box of the screening machine has a fully sealed structure, which effectively reduces the dust generated during the working process. Sieve box side plates, power transmission plates and other components are high-quality alloy steel plates, with high yield strength and long service life. The exciting force of this machine is provided by a new type of special vibration motor. The exciting force can be adjusted by adjusting the eccentric block. The number of layers of the screen can be set to 1-3, and a stretch ball is installed between the screens of each layer to prevent the screen from clogging and improve the screening efficiency. The linear vibratory screening machine has the advantages of simple structure, energy saving and high efficiency, small area cover and low maintenance cost. It is an ideal equipment for dry sand screening.
The material enters the sieve box through the feeding port, and is driven by two vibrating motors to generate the exciting force to throw the material upward. At the same time, it moves forward in a straight line, and screens a variety of materials with different particle sizes through a multilayer screen, and discharge from the respective outlet. The machine has the characteristics of simple structure, energy saving and high efficiency, and fully enclosed structure without dust overflow.
After drying, the finished sand (water content is generally below 0.5%) enters the vibrating screen, which can be sieved into different particle sizes and discharged from the respective discharge ports according to the requirements. Usually, the size of the screen mesh is 0.63mm, 1.2mm and 2.0mm, the specific mesh size is selected and determined according to actual needs.
