The screening principle of rotary vibrating screen is mainly to make the screen produce periodic swing, rotation and other movements through the excitation of the motor, so that the material can produce high-speed movement on the screen and fall into the aggregate bin below to complete the process of screening and classification.
The rotary vibrating screen can be divided into two layers of upper and lower two layers of screen, in the normal screening, the material first enters the upper screen, and the coarser material is screened out after passing through the upper screen and falls into the lower aggregate bin;The finer material falls into the lower screen through the upper screen, and continues to be screened on the lower screen, the finer particles pass through the lower screen, and the coarser particles are blocked on the lower screen, and finally all the materials with suitable particle size are screened out, and the materials that do not meet the requirements are discarded.
Rotary vibrating sieve is a kind of high-precision fine powder screening machinery, which can be used for single-layer powder impurity removal, multi-layer particle size classification, solid-liquid separation and filtration, and is widely used for screening and filtration of granules, powder, mucus and other materials.
The working principle of the rotary vibrating screen is mainly to use the excitation effect of the motor to make the screen produce high-speed vibration, so as to screen and classify the granular materials on the screen. Specifically, the screen of the rotary vibrating screen is composed of two layers, and when the material passes through the upper screen, the coarser particles are screened out and fall into the aggregate bin below;The finer particles fall through the upper screen into the lower screen and continue to be screened. On the lower screen, the finer particles are screened out, while the coarser particles are blocked on the lower screen. Eventually, all materials with the right particle size are screened out, and those that do not meet the requirements are discarded.
The advantages of rotary vibrating screen include high precision, high efficiency, high reliability, etc., so it has been widely used in industrial production.
The working principle of rotary vibrating screen has the following characteristics:
High efficiency: The screen surface utilization rate of the rotary vibrating screen is high, and the trajectory of the material running is long, which makes the screening process more efficient.
High precision: The rotary vibrating screen can finely screen the material to obtain a purer product.
Adjustability: By adjusting the phase angle of the hammer at the upper and lower ends, the movement trajectory of the material on the screen surface can be changed, so as to meet different screening needs.
High reliability: The high-speed placement of eccentric blocks of different phases at the upper and lower ends of the vibrating motor of the rotary vibrating screen produces a composite inertia force, which makes the vibrating body of the screen machine continuously reciprocate and ensure the stability of the screening process.
Easy to operate and maintain: The rotary vibrating screen has a simple structure, easy to operate, easy to clean and maintain.
In a word, the working principle of rotary vibrating screen has the advantages of high efficiency, high precision, adjustability, high reliability and easy maintenance, so it has been widely used in industrial production.
