MH Gyratory Sieve


 
Working Principle of Gyratory Sieve:
The total gyratory movement of the square gyratory sieve can rapidly spread, stratify and separate the material. The unique gyratory motion can quickly spread the material across the full width of screen at the feed end, driving the particles move forward contact with the screen surface. The large horizontal amplitude can improve the sieving effect of the near-size particles, and can improve the material handling capacity of the machine.

Gyratory Sifter

Gyratory Sift is one precision sifting equipment, Our gyratory sifter include MH model gyratory sifter, MHG side doors access gyratory sifter and round gyratory vibrating sifter.

Both MH model and MHG model gyratory sift are rectangular model sifting equiment, its sifter mesh dimension could be from 1.0m*0.6m to 2.0m*5.0m, so its capacity could cover severial KGS per hour to 200TPH refer to different mesh aperture size and mesh area. So it could be used in many industry for finnal screening.

Frac Sand Screening Equipment

Overview of MH and MHG Gyratory Screen Separator for Frac Sand:

Gyratory sifter is one proper frac sand screening equipment ,for frac sand is also called square gyratory screen, gyratory screener, square swing screen, sweco type gyratory screen, gyratory separator etc.

Simple pursuit of sieving accuracy will be at the expense of yield, while the pursuit of large yield will decrease the accuracy. Gyratory sifter for frac sand is a kind of screening equipment with the characteristics of low failure rate, low downtime rate, low cost, and high output, high precision, high efficiency,, which is specially designed for the above problem.

Gyratory sifter for frac sand is widely used in the industries including chemical, metallurgy, ferrous metal, non-ferrous metal, food and abrasive.

The screening machine can be equipped with one to four layers of screen

Working Principle of Gyratory screening equipmentfor Frac Sand:

The total gyratory movement of the square gyratory sifter can rapidly spread, stratify and separate the material. The unique gyratory motion can quickly spread the material across the full width of screen at the feed end, driving the particles move forward contact with the screen surface. The large horizontal amplitude can improve the sieving effect of the near-size particles, and can improve the material handling capacity of the machine.

Urea Screening Equipment

In the Urea production process, the urea prill need to be screen after granulating, for Granular Urea , the request size always is between 2mm to 4mm.

The gyratory screener is one must screening equipment in some urea production process technic document.

And the MH model gyratory screener could finish the urea screening indeed according to its working principle, want more details for the gyratory screener in the urea screening industry, please feel free to contact us.

Sugar Screening Equipment

The sugar screening equipment is one important equipment during sugar production process, its screening precision is one key parameter of the sugar quality.

For sugar screening, it include sugar grading, scapling and fines removing .

When for sugar salping, it for removing  lumps and foreign particles from sugar,  the mesh aperture size always over 2mm, and the MH model screener with single layer deck will be ok, its capacity for sugar scalping is huge.

When for sugar fines removing, it main reduce the dust amount in the finished sugar production before package.  Because the mesh aperture always is very little, and it is easy to block the mesh, so it need one screener that with self-cleaning device, and it also need to be easy to change mesh when mesh worn out, our MHG side doors access gyratory screener could meet the equest for sugar fines removing screening.

Compount Fertilizer Screening Equipment

The compount fertilizer is one huge range fertilizer include NPK, monoammonium phosphate, diammonium phosphate, potassium nitrate, urea ammonium phosphate, potassium dihydrogen phosphate, ammonium nitrate phosphate, phosphate nitrate, ammonium chloride phosphate, ternary compound fertilizer of nitrogen, phosphorus and potassium, ammonium phosphate, etc.

During the fertilizer production process, it need screening equipment for grading, scalping or fines removing.

But the dust of the fertilizer always easy to absorb the moisture from the air then become sticky, it is easy to ahere to the mesh wire, then block the mesh aperture.

The the screener need to be with self-cleaning device to reduce the mesh aperture blockage problem.

Our MHG model side doors access gyratory screener not only with self-cleaning balls for the fertilizer, it also could change mesh from two side of the screener box, that means the worker could finish the mesh changing work within 10 mins, it let the equipment down time as short as possible. It is one proper compount fertilizer screening equipment.

Silica Sand Screening Equipment

MHG model gyratory screen is one proper screening equipment for silica sand screening.

In many industry, the customer need very fines silica sand, and the fines size always less than 20mesh , and even reach 200mesh.

In tradtional application, the linear vibrating screener is one major equipment for slica sand.

But linear vibrating screener always has its disadvantage when screening silica sand, such as the capacity is not too large, the mesh service life is short and mesh changing work is not easy.

Our MHG side doors access gyratory screener could satisfy the request on the silica sand powder screening, want more details, please feel free to contact us

The Rotex model do the The Gyratory Reciprocating Motion as following

 

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.
