YBS seriestumbler vibration screen is designed formanufacturers who produce largely and sieve in high density. The simplestsieving is eyes observing and hands sieving. And YBS series tumbler vibrationscreen is mechanical analogue for this. It is the most effective to simulatethe movement of artificial screening (screening accuracy, efficiency and lifeof screen are 5~10 times of normal round screen).

1.      Characteristic

The output is up to 5 times per area; its accuracyis 6 separation, and screening efficiency is up to 90%~95%; usage of efficientnet cleaning device system, such as Silicone rubber ball and ultrasonic wavecan stop sieve blocking; sealed dusting and safe operating; Acceleration is 4.5timeslower thanvibrating screen, life of spare parts is improved to reduce maintenance; Noiseis less than 75db.

2.      working principle

Tumbler vibration screen is one kind of imitationartificial vibrating screen in low frequency. Its principle is: instantaneousmotion is synthesis of the radial displacement and its circular motion. Thatis, it can lead to nonlinear three-dimensional motion by adjusting the vibratorof eccentric distance, and materials can also produce the same motion like manualoperation. Then it can get to the purpose of screening. It can achieve moreideal result by matching up other spare parts. The materials meet the followingconditions can use this kind of machine: Spherical, cylindrical, sheet, erose,easy plugging and need precise sieving.

3.      structureprinciple

·The basic rotary motion is similar to artificial screening. Adjustableeccentricity from 25MM to 40MM and adjustable low speed V belt drive from 120RPMto 360RPM.

·The stayingtime of each kind of product can be adjusted in the direction of driveaxis by radial direction and corner cut of tumbler vibration screen.

·Establish level and throwing three-dimensional tumbling motion.Materials evenly disperse in the entire screen surface from the center to theouter edge, thereby spreading small particles to axial direction in spiralmotion to complete the wholescreening process.

·Horizontal and verticalacceleration increase as particles move and the particles whose sizes are closeto the mesh size will be separated successfully: Larger particles aretransported to the exit and there is as adjustable guiding device controllingflow rate at the exit. This guiding device is another factor to control thestaying time of materials.

·This process is repeated during each sieve layer.
