MH model Gyratory Screen

 This MH model gyratory screen is the  traditional and classic model screening equipment. It is similar with the Rotex  screener.

 And it is best seller production of  Mega Young Screening Technology Co.,Ltd, compare with other sifting equipment  models, the gyratory sifter sales amount is largest, and the performance and  influence of the gyratory sifter have been proven by different customer in  different industry applications.

The MH model gyratory screen have  following structure

1.Fast clamp on top cover

2.Automatically tensioned Screens with  spring clips

3.Ball tray structures

4.Specific design

Reciprocating-gyratory motion

Stage 1  Circle stalge

 When the material fall onto the  gyratory sifter deck from inlet, the material will disperse soon until the  material bed cover screen mesh along the screen width.

Stage 2 Ellipticl stage

 After first stage material  spreading, the material bed thickness is suitable for screening now, and the  material movement path become the elliptical from circle, the most material  screening and sifting work will be done in this stage.

Stage 3  Linear stage

 After first two stage sifting, the  material screening work almost finished in this stage, the material movement  path become linear from elliptical, the path distance will be short and the  material will flow out from the gyratory sifter outlet soon.

The gyratory sifter work principle  as following:

 1. The materials do the reciprocating-gyratory motion along with the gyratory  separator running, and there is not vertical jump during the gyratory screener  running period, the little size material will go to the bottom of the flow bed  along moving forward, the material particle will pass the mesh aperture when  the particle size is less than the gyratory separator aperture size. The  reciprocating gyratory motion will make the material flow bed touch the  screener mesh surface with longer time for increasing the screening efficiency.

 2.The reciprocating gyratory motion of the gyratory separator will spread the  material flow bed evenly along with the screener mesh bed after material fall  into the inlet, the material flow bed will be very thin after being spread, it  is good for material screening , and the material screening precision and  capacity will be increased.

 3.The screen deck of gyratory separator equipment consist of mesh, spring  clamp, ball trays and self-cleaning balls. The self-cleaning balls jump  ceaselessly along with gyratory screener operation, the ball could hit the  screen mesh in order to let the mesh vibration, so the material blocked in the  mesh aperture or adhered to the mesh surface will be cleaned out, it could make  sure the aperture ratio so guarantee the screening efficiency.

 4.The gyratory separator do not have vertical vibration, so it do not have much  load request on the base foundation, it is much lower than the vibration model  screener, so the gyratory screener could save steel structure cost, the  customer do not need to consider the install load limited.
