The use of vibrating screen is becoming increasingly widespread in various industries, among which ultrasonic vibration sieve and round vibro sifter are the most widely used among circular vibrating screen. These two types of equipment have extremely similar appearances, and many people cannot distinguish between these two types of equipment. So, what is the difference between these two types of equipment?
1.Working principle: The excitation force of the round vibration sieve comes from a vertical vibrating motor fixed in the low cylinder. There are eccentric weights at the upper and lower ends of the vibrating motor, which transform the rotational motion of the motor into horizontal, vertical, and inclined three-dimensional motion. This motion is then transmitted to the screen surface, causing the material to expand outward on the screen surface.Ultrasonic vibration sieve is a type of vibrating screen that combines the ultrasonic controller with the vibro sifter. This system introduces a low amplitude, high-frequency ultrasonic vibration wave on the screen mesh based on the traditional vibrating sieve. The ultra-fine powder receives ultrasonic acceleration, keeping the material on the screen surface in a suspended state, thereby suppressing blockages such as adhesion and friction leveling.
2.Different yields: The rotary vibration sieve is used to screen materials with smaller mesh sizes, with an hourly yield of 50kg.The ultrasonic vibration sieve prevents the material from clumping and sticking, prevents blockage, and has a processing capacity of up to 140kg per hour.
3.Screen cleaning function: The ultrasonic vibro sifter uses high-frequency ultrasonic pulses to clean the screen, with high screening efficiency, no clogging, and high screening accuracy. The round vibro sifter does not have an automatic cleaning function.
4.The rotary vibrating screen is suitable for screening materials with small mesh size, such as soybean milk slag removal, flour impurity removal, etc., but it is not ideal for screening viscous, electrostatic or ultra-fine powder, which is easy to cause problems such as mesh blocking and no blanking. And ultrasonic vibrating screen can solve this problem. The ultrasonic vibration wave generated by ultrasonic rotary vibrating screen can suppress the agglomeration of materials on the screen and prevent blockage.
In summary, although they have similar appearances, there are essential differences between the two. Therefore, when choosing screening equipment, one should choose according to the material they are screening.
