Supply Vibrating Screening Machine

1.YBS seriestumbler vibration screen  isspecially designed for manufacturers who produce largely and sieve in highdensity. The simplest sieving is eyes observing and hands sieving. And YBS seriestumbler vibration screen is mechanical analogue for this. It is the mosteffective to simulate the movement of artificial screening (screening accuracy,efficiency and life of screen are 5~10 times of normal round screen) andsuitable for all refined and ultrafine materials, especially for materialswhich are difficult to deal with. 2.Characteristic The output is up to 5 times per area; its accuracy is6 separation, and screening efficiency is up to 90%~95%; usage of efficient netcleaning device system, such as Silicone rubber ball and ultrasonic wave can stopsieve blocking; sealed dusting and safe operating; Acceleration is 4.5 times lowerthan vibrating screen, life of spare parts is improved to reduce maintenance;Noise is less than 75db. 3.       working principle Tumblervibration screen is one kind of imitation artificial vibrating screen in lowfrequency. Its principle is: instantaneous motion is synthesis of the radialdisplacement and its circular motion. That is, it can lead to nonlinearthree-dimensional motion by adjusting the vibrator of eccentric distance, andmaterials can also produce the same motion like manual operation. Then it canget to the purpose of screening. It can achieve more ideal result by matchingup other spare parts. The materials meet the following conditions can use thiskind of machine: Spherical, cylindrical, sheet, erose, easy plugging and needprecise sieving. 4.        structure   principle 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 staying time of each kind of product can be adjusted inthe direction of drive axis by radial direction and corner cut of tumblervibration screen. Establish level and throwing three-dimensional tumblingmotion. Materials evenly disperse in the entire screen surface from the centerto the outer edge, thereby spreading small particles to axial direction in spiralmotion to  complete the whole screening process. Horizontal and vertical acceleration increase as particlesmove and the particles whose sizes are close to the mesh size will be separatedsuccessfully: Larger particles are transported to the exit and there is as adjustableguiding device controlling flow rate at the exit. This guiding device isanother factor to control the staying time of materials. ·Thisprocess is repeated during each sieve layer. 5.Applicable industries Chemistry,foodstuff, spice, plastic, mining industry, medicine, wood industry, plywood,metallurgy, rubber, fodder, chemical fertilizer, sugar and salt industry,renewable industry.
