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.

 

 

 

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.

 

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

China Rotex Screen

Mega Young Screening Technology Co.,Ltd is one professional screening equipment designer and manufactuer in China, the MH model gyatory screener is similar with Rotex Screener,  the gyratory screen is drived by one gyratory device on the driving head end.

Mega Young Screening technology has supplied many sets such model gyratory screener to customer, they are widely used for many industry such as fertilizer, sugar, salt, sand, perlite, activated carbon powder etc

 

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.

Food Grade Salt Screening

 

Salt comes in many forms including salt for consumption (table salt), or salt that is used to de-ice roads (rock salt). When it comes to salt screening, rates and efficiencies are the key factors. Often times, companies in the salt manufacturing industries need rates of over 100 tons an hour without compromising their ability to get an effective cut. Traditional vibration screeners have been used for these applications for years, but they have proven ineffective in lower micron ranges.

The food grade salt size always is between 20mesh to 60mesh, normal vibration model screener do not have high screening precision when meet high capacity request.

But the MH model gyratory screen could meet the salt screening request on large capacity and high screening precision.
