The basic principle of plastic rotary vibrating screen

Plastic rotary vibrating screen is a series of vibrating screens that use a heavy hammer (unbalanced weight) installed on the motor shaft to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface, causing the material to undergo outward expansion involute motion on the screen surface. Therefore, this series of vibrating screens is called rotary vibrating screen. The rotary vibrating screen has the advantages of long material trajectory and high utilization rate of the screen surface. Adjusting the phase angle of the upper and lower heavy hammers can change the motion trajectory of the material on the screen surface Materials can be subjected to precision screening, probability screening, and other methods.

Basic functions of plastic rotary vibrating screen

Screening:

Screening is the process of dividing solid particles into different groups of particles of equal size. A single machine can be equipped with one to five layers of screen mesh, which can accurately and continuously separate two to six particle segments simultaneously; The grading accuracy is over 95%.

Screen out impurities:

High precision sieves can quickly remove large or small particles with low percentage content during high flow material processing. Mostly used as a single layer. The advanced design of the vibrating screening filter machine ensures high efficiency and quality in removing impurities; The accuracy can reach over 98%.

Slurry filtration:

Plastic rotary vibrating screen can quickly remove insoluble large particles from various slurries. Mostly used as a single layer. The specially designed screening filter has a filtration capacity of up to 20 cubic meters per hour.

Characteristics of plastic vibrating screen:

·Mesh anti clogging - The plastic rotary vibrating screen function and the automatic cleaning and blocking device designed by our company reduce the probability of clogging.

·Single layer or multi-layer sorting - Each SV polypropylene vibrating screen can choose one to three layers of screen mesh, which can simultaneously perform two to four levels of sorting or filtering.

·Efficient and precise screening - all incoming materials are automatically discharged, and there are no stored materials inside the machine. The same screening surface has a larger capacity than other types of screening machines. The new patented structure screen holder developed by our company reduces the percentage of undersized material in the material on the screen outside the discharge machine compared to other types of machines.

·Convenient replacement of screen mesh - Plastic vibrating screen machines have various grid structures according to different needs; One of them reduces the time for replacing the screen mesh to 3-5 minutes, saving 30-60 minutes compared to other types of screening machines. The sieve has a longer lifespan and higher efficiency.

·Vibration without mechanical conduction - The new vibration source of plastic vibrating screen generates strong and stable three-dimensional vibration, and the equipment can be installed in any desired position and is easy to move.

·Economic and Environmental Protection - The long lifespan of the entire machine and screen, low energy consumption, low maintenance costs, high efficiency, and ease of replacement make the equipment cost-effective. Low noise, fully enclosed, outstanding environmental performance.

·By changing the phase angle or mass of the oscillator, the power source can drive the oscillator to generate different excitation forces, thereby changing the horizontal or vertical amplitude, thus affecting the screening flow rate and efficiency coefficient.
