Walnut Shell Filter and Applications

Walnut Shell Filter

Walnut shell filter is one type of separation equipment which adopts filtration separation principle. Walnut shell filter adopts the walnut shells as its filtering mediums, because the walnut shells has the features of hydrophilic but not oleophylic, and when the walnut shells are broken up into small sizes, it increases the superficial area of walnut shells greatly, and even more the walnut shells has excellent absorbability, as a result the walnut shells has high oil removal rates. The walnut shell filter has two control ways, automatic and manual. The oily waste water flows into the walnut shell filter from up to down, through water distributor, walnut shell filter material layer and water collector, the filtering finishes. When backwashing or back flushing, the stirrer overturns the walnut shell filter materials, the water flows from down to up, making the walnut shell filter materials be washed fully, and the walnut shell filters materials can be used again. 

Walnut shell filter applications 

1. Oily waste water treatment in oil filed, petrochemical, metallurgy industry

2. Oily waste water treatment in seaport, quay, oil depot

3. Oily waste water treatment in ships or vessels

4. Oily waste water treatment in steel industry, metallurgy industry, coal industry

5. Oily waste water recycling system in steel industry, metallurgy industry, coal industry

6. Water fine filtering in oil field and offshore oil drilling platform

Walnut shell filter materials and walnut shell grinding materials

Walnut shell can be used as two main materials, filter materials and grinding materials.

• When walnut shell is used as filter materials, the walnut shell is mainly put into the walnut shell filter equipments, when the fluids go through the walnut shell filter from the equipment suction to discharge, the impurities are attached onto the walnut shells, achieving the filtering purpose. Walnut shell filter materials are mostly used in the oil filed, to remove the oil dirt of oily water. In the processing of walnut shell filter materials, it is simplier relatively. Just needing breaking up the walnut shells into small mesh sizes, and removing the other impurities from the walnut shells. Normally, the walnut shell filter materials are big mesh sized of 6# - 35#.
• When walnut shell is used as grinding materials, or abrasive materials, its processing is more complicated that it requires the surfaces must be smooth without any corner, otherwise the walnut shell will damage the surfaces of other objects when used as grinding materials. For example, when the walnut shell is put into spay gun as grinding materials to polish other objects, the walnut shell will damage the surfaces of other objects if the walnut shell has corners itself. And the grinding materials have wider range of mesh sizes, which include all of the mesh sizes from 4# to 200#.

Fine Grade Walnut Shell Powder Applications

Because the hardness of walnut shell is too big to not easy to break up, this special property brings big business opportunities. The American investigator finds out the walnut shell will have wide application after being super-micro broken up.

In the metal washing industry, walnut shell can be used as metal washing materials and metal polishing materials after treatment. For example, the aero engine, circuit board, steamer gearing and car gearing can be washed by treated walnut shell. After being broken up into fine particles, the walnut shell will have certain elasticity, restoring force and admitted weight, so the walnut shell can be used as abradant in the stream washing operation.

In the oil industry, it’s difficult for oil drilling and mining in the ruptured stratum and loose geology. In this case, it is possible to adopt walnut shell super fine powder to fill in as bridging agent, making sure the oil drilling and mining can be taken freely.

In the senior painting industry, after being processed, the walnut shell can be added into paint, making the paints have similar texture with plastic, whose performance is rather superior to normal paints. This kind of paints can be painted onto plastic, wallpaper, brick and wallboard to cover the cracks on them.

In the explosive industry, putting super fine walnut shell powder into the explosive with other additive can increase greatly the explosive power.

In the cosmetics industry, because walnut shell super fine powder is pure natural material without any toxic substances, walnut shell powder can be used as one type of coarse gritted additive agent in the soap, toothpaste and other skin care agents with excellent effect.

The processing methods of super fine grade walnut shell are as follows:

1.       Grinding medium crushing
The Grinding medium crushing is depending on the acting force between the walnut shell and moving medium breaks the walnut shell up into pieces. The typical equipment is ball crusher, mixing mill, etc. The walnut shell grain sizes processed by grinding medium crushing are a little bigger and uneven.

2.       Mechanical shearing super fine crushing

The mechanical shearing super fine crushing is normally applied to the processing of toughness materials and flexible materials.

3.       Airflow super fine crushing

The airflow super fine crushing uses supersonic airflow as the grits carrier, along with airflow movement, the grits collide with each other, achieving in the purpose of breaking up into pieces. The types of airflow super fine crushing includes flat type airflow super fine crushing, circulating pipe type airflow super fine crushing and injecting type airflow super fine crushing. The walnut shell grain sizes processed by airflow super fine crushing are even. And even more that the grits temperature rise is very low. According to the walnut shell characteristic, adopting airflow super fine crushing processes fine grade walnut shell powder is the ideal choice.

Now in the USA, there are already some manufacturers sell the super fine walnut shell powder. And we have confidence that the walnut shell marketing will be larger and larger in the future, even the value of walnut shell will exceed that of walnut kernels, along with the walnut shell is found out having more and more applications.
