筛分面积Screening surface (m2)
Tumbler screen is an efficient sieving machine which is designed to meet the large output, high-density sieving of the manufacturers. The simplest sieving is hand sieving by eye. This is mechanically simulated by the tumbler screen, which takes the most effective simulation of the artificial sieving movement (sieving precision, efficiency, sieve life is 5-10 times than usual sieving machine).Tumbler screens are suitable for all powders and granular materials in the fine and ultra fine range , especially for materials which are difficult to sieve.
Up to 5 times output per unit area; accurate to 6 Level separation, sieving efficiency is as high as 90% -95%; when using the silicone rubber balls, ultrasonic and other high-performance mesh-cleaning device system, the mesh hole will not be blocked. whole sealing structure design, safety operation; the acceleration is 4.5 times lower than vibrating sieve, sieving parts’ increases the life expectancy and reduces maintenance; noise<75 dB. Re-optimization is balanced, ground-based dynamic load is low.
⊕ Working Principle
l Basic rotary motion is similar to hand screening .The eccentricity is adjustable from 25 to 40mm, low-speed V-belt drive is adjustable from 120 to 360rpm
l Each product’ dwell time can be adjusted in a radial and tangential angle ,towards the drive axis.
l Therefore, establishing the horizontal and throwing three-dimensional rolling movement, materials are evenly dispersed on the entire sieve surface from the center to the outer edge, and thus spread towards the axis by spiral movement. Small particles are then finished in the whole sieving process.
l The horizontal and vertical acceleration are increased with the movement of the particles, and then the particles which are close to mesh size will be successfully separated; The larger particles are transported to the exit, the flow can be controlled by a regulated oriented device at the exit, the oriented device is another factor which controls the dwell time of the materials.
l The process is repeated in each layer.
