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.

What is a Walnut Shell Filter?

Although filtration is the most effective method of removing the suspended matter in the water, but to the water including oil and grease, the normal filtration processing does little. Walnut shell filter is developed especially to treat the waste water including oil and grease.

Walnut shell filter is normally applied to oil field and other oily sewage. Presently, the walnut shell filter is playing a great role in oily waste water treatment in various industries.

Walnut shell filter adopts walnut shell after special processing as filter medium. Walnut shell has strong adsorptive interception capacity (adsorption rate: 25~53%) and stress tolerance (23.4kgf/cm2); walnut shell can be backwashing and regeneration; walnut shell has strong the chemical property of walnut shell is stable not easy to dissolve in the acid solution or alkali solution; the hardness of walnut shell is strong; walnut shell has good abrasion resistance, not needing replacement for long time; walnut shell has good hydrophilicity and oil impregnation. Because the specific gravity of walnut shell (1.255g/cm3) is bigger than that of water, it’s easy for backwashing and regeneration. And even its biggest advantage is adopting the water before filtration directly to back wash, not needing the help of air supply and chemical agents. As a result, the running costs of walnut shell filter is low; the management of walnut shell filter is simple; the backwashing strength of walnut shell filter is small; the filtration effect of walnut shell filter is good; the filter materials of walnut shell filter is not easy becoming putrid for long time; and even more, the walnut shell filter can be used singly or double in series according to water quality requirements.

How to Know the Walnut Shell Qaulity is Good or Not?

Hi everybody,
How are you today?
In the last week, I introduced to you the various walnut shell applications, and you may know that the walnut shell has so many functions actually, and the walnut shell is serving our daily life although we don't feel it. But how to check the walnut shell quality, in other words, how to know the walnut shell is good or not. Today, I'd like to introduce to everybody.
1. See the color of the walnut shell: Good quality walnut shell is with lighter color, which is close to yellow brown; while defective walnut shell is with red-brown color.
2. Processing raw materials: Good quality walnut shell is processed from the core of the shells of walnut without the surface layer of the shells of walnut, in other words, before processing good quality walnut shell, must putting off the surface layer of the shells of walnut firstly, being the raw materials of processing the good qulity walnut shell. But defective walnut shell is processed by breaking the walnut shell raw materials into different sizes directly and justly.
3. The price: good quality walnut shell is with higher price, because it must have one more processing of selecting good raw shells o walnut. As you know, if putting off the surface layers of the shells of walnut, there will be little shell cores left for processing good quality walnut shell. For example, if collecting 1,000.00kgs raw materials of walnut shell, there will be only less than 500.00kgs of shells core of walnut left for processing good quality walnut shell. On the other hand, the bag quality walnut shell is with lower prices, because its processing costs is lower basically.
4. The walnut shell purity: Good quality is must 100% pure shells of walnut, without any other foreign matters, for example the shells of coconut. But the defective walnut shell is not pure walnut shell, the manufacturer mixes different other matters into it, because the costs of these foreign matters is lower than the shells of walnut.
The above four points are the main differences between good quality walnut shell and bad quality walnut shell. In the future, if somebody have need on the walnut shell, hoping these four points could be help to you when buying the walnut shell.
