Working principle of vibrating screen:
● The motor is powered and rotates, and the belt drive mechanism adjusts the speed;
●Transmit the driving force to the main drive shaft through the countershaft pair;
● Drive the vibrator to operate to generate linear vibration force, and the direction of the excitation force forms an angle of 45° with the horizontal;
● The linear vibration force acts continuously and reciprocally on the screen body, causing the screen body to vibrate on the buffer spring. At the same time, the buffer spring reduces the dynamic load of the screen body on the support foundation of the screen machine;
● The screen body drives the screen surface to vibrate synchronously and transmits force to the materials on the screen. The impact materials are thrown up on the screen surface, advance to stratification, and are graded through the screen according to the specified particle size;
● Materials are continuously buffered and input from the feed chute to the material receiving plate, and are screened through the screen surface. The materials under the screen are discharged into the under-screen chute, and the materials above the screen are discharged into the discharge chute;
The banana screen applies the principle of equal thickness screening to improve the processing capacity and screening efficiency of the screening machine.
Take the ABS3661 single-layer banana screen as a typical example. This screen type adopts a 5-angle and 5-section folded line screen surface. The inclination angles of the screen surface from the feed end to the discharge end are 25°, 20°, 15°, 10°, and 5° respectively. Decrease step by step. Under the action of the exciting force, the materials are continuously projected toward the discharge end on the screen surface to form a flow stream. The greater the inclination angle of the screen surface, the faster the flow rate. The feed end feeds a lot of material, but the inclination angle of the screen surface is large, which speeds up the movement of the material, and the material layer quickly becomes thinner and stratified quickly. The middle sections and the discharge end screen surface process the materials that have been partially screened in the previous section step by step. The materials gradually decrease and the inclination angle flow rate gradually decreases.
Since the thickness of the material layer on the screen surface is proportional to the feed amount and material flow rate, the thickness of the material layer is basically equal on each section of the screen surface from the feed end to the discharge end, so that the material layer thickness is appropriately and reasonably distributed on the screen surface to facilitate screening. This increases the chances of contact between the fine particles and the screen surface to facilitate screening.
