Sweep, more wonderful
Vibrating screen is used for the classification, impurity removal, screening, filtration of the corresponding materials, and is widely used in chemical, food, medicine, metal metallurgy and other industries. Due to the wide range of industries, the materials screened are also different, but the working principle of the vibrating screen is basically the same.
The working principle of the vibrating screen is to use the high frequency vibration of the screen body to screen and grade the material. But its motion path is more diverse, although there are many kinds of vibrating screen equipment, but are the use of vibration motor as a power source, and the vibration motor in the body of the different installation of the combination of forms, will produce a different trajectory. Now, let's take a look at what kinds of trajectories it presents.
First, the circular vibrating screen uses a circular motion trajectory, in the longitudinal profile perpendicular to the screen surface, the central motion trajectory of the sieve vibration mass is circular or close to circular, usually installed a vibration motor can produce this motion.
Second, the rotary vibrating screen is equipped with two eccentric block of inertia vibrating screen, by adjusting the Angle between the eccentric block, can change the motion of the screen and meet different process requirements. When the vibration motor rotates, under the action of centrifugal force generated by the eccentric block, the motor together with the support, base, screen frame and screen are doing high frequency vibration, the material can be added from the screen frame above, the fine particle material through the screen is discharged from the material pipe, the coarse particle material not through the screen is discharged from the other material pipe, due to the role of two eccentric blocks, under normal circumstances, The resultant force of the exciting force does not pass through the heart of the vibrating part, resulting in an exciting moment. In this way, in addition to the circular vibrating screen can do circular track vibration, but also can be rotated motion.
Third, the linear vibrating screen is a double vibration motor, when the two vibration motors do synchronous, reverse rotation, the eccentric block generated by the exciting force in the direction of parallel to the motor axis offset each other, in the direction perpendicular to the motor axis stacked as a force, so the motion trajectory of the screen machine into a straight state.
The above is a summary of the working principle and movement trajectory of the three vibrating screens, hoping to help you in need.
