Rotary sieve


Tumbler screen machine is a kind of inertial equipment with mature technology and classical application. Its new design Philosophy and unique structure making it the closest manual screen machine. The Tumbler sieve machine have bright application prospects for its perfect screening effect. From the aspect of its trajectory, it is a non-linear inertial vibrating screen. The Tumbler sieve machine is particularly used to classify small materiels and fine powder according to its unique structure and working principle. It is not only apply to dry sieving, but also wet sieving. It is widely used in mine, building material, metallurgy, foundry, abrasive material, chemical, light industry, medical, food and other industry.


Working Principle of Rotary Sieve, Tumbler Screen:
Because of the motion trajectory of the griddle box, the Tumbler screen machine is also called compound circle screen. The vibration force produced by the drive system is a kind of inertia force which is circling the dead axle and changing regularly. Intrinsically, it is a kind of centrifugal force given by the eccentricity mass circling around the dead axle. The sieve is usually installed horizontally or with tiny angle(0°-5°). The principle is:when you start the machine, the vibrating part ---the screen box takes circling motion under the influence of the vibrating force.The screen box drive the sieve to take circling motion periodicity,so the material on screen surface take bounce motion, meanwhile, the material less than the aperture drop to the next deck,and the oversize are discharged by the outlet.Finally ,the screening work is completed. From the aspect of its structure and working principle, the exciter can circumgyrate in two ways according to the motion of the material, uniformily or contrarily. As a result ,we'd better make a choice between throughput and efficiency according to our practical demand.
Features of Rotary Sieve, Tumbler Screen:
(1)High efficiency, refined design, duration, any powder and mucilage are suitable for sieving.
(2) Easily to replace the net, simple operation and convenient washing.
(3) Never clog the mesh, no powders fly up, minimum sieving size is 500meshes or 0.028mm.
(4) Discharge the impurity and coarse materials automatically, and continuous operation.
(5) Unique net-frame design, long life for using, only need 3-5 minutes to replace the net.
(6) Small volume, move easily.
(7) The most layers of the sieve are about 5, but 3 are suggested.high quality low consumption
Characteristic of Rotary Sieve, Tumbler Screen:
The vibrating sieve is a universal device designed with full demonstrability and utmost optimization and have the tend to be standardized. It is very suitable to separate small particle, minuteness powder and the separation of solid and liquid.  
1.     This vibrating sieve is one of precised powder sieve,it is of high efficiency,and the screening exceeds 90%.
2.     It adopts whole sealing structure design,the sealed effect is fairly well,no dust pollution,no leaking liquid,no material left in machine,and no dead angle in the net frame.
3.     Small volume and light weight,easy to be installed and maintained.
4.     The outlet can be adjusted at any angle,and it is easy to replace the screen.
5.     the rubber ball device can reduce the changce of jam on the screen.
6.     By adding the device ultrasonic instrument conversion device,  superfine materials up to 600 mesh can be sieved.  
Scope of application of Rotary Sieve, Tumbler Screen:  
Vibrating sieve is widely used in many industries, such as mining,building,materials,metallurgy,casting,abrasive,chemical,light industry,medicine and food industry.
Principle of the structure.
It uses vertical motor as the source of vibration, with eccentric hammer on the both sides of motor ,change circumrotate to level ,upright and incline movement,then pass these three movement to surface of the screen. Adjust the phasic angle on the both sides of the top and bottom to change the movement track of the surface screen. This will help to screen different materiel in different situation successfully.  
Installation of Rotary Sieve, Tumbler Screen:
1.There are seven Specifications for this series vibrating sieve, materials using in each part can be customized .
2.Pls confirm the voltage and if the motor  request for explosion-proof .
3.we can also accept special orders.
