ADVANTAGES OF USING WALNUT & PECAN SHELL MEDIA IN DRILLING

– Combines high strength, shape and size to make a premium product
– pH or temperature do not affect the activity of Walnut Sell media
– Resists fermentation
– Applicable in all drilling fluids, including oil mud

Applications
Walnut shells are primarily used, alone or in combination with other shaped materials, to regain or cure lost circulation. The fine variant can be maintained in a circulation system without bypassing the shale shakers; however, medium and coarse grades will be removed with cuttings on the shakers. Their hardness renders walnut shells resistant to deformation by hydrostatic pressure. Consequently, plugging or bridging efficiency is maintained.
Walnut shells also exhibit high chemical resistance and are unaffected by pH and temperature, making them useful inoil-based drilling fluids as well as all aqueous systems.
Secondary uses include torque reduction and as a scouring agent to clean balled bottomhole assemblies.

Usagedrilling
The typical treating levels for prevention range from 2 to 5 lb/bbl (5.7 to 14.3 kg/m3). For more severe losses, when the material is pumped as a pill or squeeze, levels from 10 to 50 lb/bbl (28.5 to 142.7 kg/m3) are recommended. Severity of loss and the amounts of other materials incorporated in the mix will dictate the appropriate concentration.
Walnut shells should be stored in a dry location, away from sources of heat or ignition.
Consult the MSDS, safety posters, and/or product label before use, and use personal protective equipment as advised.

Advantages
Combines high strength, shape, and size to make a premium product
Is unaffected by pH or temperature and resists fermentation
Is applicable in all drilling fluids, including oil mud

Walnut shell grits perform a significant work in oil wells to regain lost circulation like throughput for purification of oily process water and industrial wastewater applications. The subfigure gives a general information about working principle of the Walnut Shell filter system:

Walnut Shell filters can manage higher inlet solids and oil by comparing with other technologies. Also, Walnut Shell filters have a much lower utility requirement when compared to other multimedia filters since there is no gas-scouring stage during backwash.

Nutshell filters provide a high throughput for purification of oily process water and industrial wastewater. The nutshell filters can handle higher inlet solids and oil, compared with other technologies. And, since there is no gas-scouring stage during backwash, nutshell filters have a lower utility requirement when compared to other multimedia filters.

EFFICIENT SOLUTION

Walnut shell is used as lost circulation material to combat typical operational problems associated with drilling mud losses. Walnut shell is an easy and efficient solution to lost circulation problems. Walnut shell does not significantly change mud properties and can be removed and perhaps recycled with ease.


Walnut shell blasting is used for stripping paint & coatings from cars, boats, buildings, furniture, fiberglass, steel and wood. The method can be employed as air blast or wheel blast equipment to propel walnut shell media.

Walnut shell blasting provides the aggressiveness to remove tough paints & coatings without damaging softer substrates since walnut shell media is a soft abrasive material. Also, walnut shell blasting makes “selective coating removal” possible. Hereby, the top coating can be stripped while leaving under-coatings original.

In addition, walnut shell blasting does not cause silicosis and therefore this method is an excellent alternative to sandblasting.

Why You Should Use Walnut Shell in Blasting?

EXCELLENT DURABILITY

Walnut Shell abrasive is a hard and fibrous product made from crushed walnut shells in accordance with International Trade Standard. It is the most common type of soft abrasive for industrial use. Walnut Shell has excellent durability, and is now widely used to blast clean and polish soft metals, glass, fiberglass, wood, plastic and stone.

DEBURRING

Walnut Shell is used in both tumbling and vibratory applications for polishing gems and jewellery. It also works as a de-burring and de-flashing product for molding, casting and electrical parts.

WITHOUT DAMAGING

Walnut Shell is ground to various sizes ranging from coarse to extra fine, allowing for a fine degree of control over the desired finish. Like other soft media, Walnut Shell cleans and removes matter from surfaces without damaging underlying material.

COST

Laboratory experiments have indicated that all media compounds may be somewhat corrosive and leave an adherent scale if they are deposited on hot metal surfaces (i.e. at 1500°F). Field experience, however, has indicated that the chance of such media actually depositing on hot components is fortunately very remote. Walnut Shell abrasive can be reused many times which will be reducing costs.

Walnut Shell Blasting can be separated into two general areas due to the intended uses:

Cleaning & Deflashingblasting

Cleaning & Deflashing with walnut shell media is used to remove grime, debris and grease from engines, valves, turbines, molds and tools. It can also clean plastics and metals without damaging surfaces since walnut shell media is a soft abrasive material. And all, walnut shells are used for “deflashing” that is also called “deburring” of plastic parts.

Besides, Walnut Shell media is used for polishing jewellery and precious stones. It is also good as a de-burring and de-flashing product for molding and casting.

Tumbling & Polishing

polishing 2

Walnut shell media can be used for cleaning and polishing metal parts in vibratory tumblers. It is usually treated with a polishing compound to enhance the result. When walnut shell media is mixed to a polishing compound, dirty metal parts are left clean and shiny.

Walnut shell polishing media is a hard and fibrous product made from crushed walnut shells in accordance with International Trade Standard. The walnut shell polishing medium is ground to various sizes from coarse to extra fine depending the application, allowing for a fine degree of control over the desired finish.Walnut shells are used in many polishing and/or deburring applications. Walnut shell media is used for polishing or cleaning fine metals, alloys, mechanical parts, shell cartridges, eye glass lens, rocks, stones, coral, ivory, beans, and seeds. Walnut shell is used as an polishing media similar to sand for polishing or deburring but without the negativities associated with other abrasive materials. Because walnut shell polishing is a gentle, non-corrosive environmentally friendly method of removing burrs, splinter, rusts, wets, edges and corners, without scratching, etching, pitting the substrate material / underlying surface or marring cleaned areas. When used as a polishing media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a ‘soft polishing media’. Walnut shell polishing media is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
Like other soft media, Walnut shell cleans and removes matter from surfaces without damaging underlying material. Jewelers use walnut shell media treated with rouge in both tumbling and vibratory applications for polishing gems and fine jewelry. When polishing the media size should be small enough to freely pass through openings or large enough to avoid lodging in openings or crevices.

The cosmetic and personal care industry use crushed walnut shell media as an exfoliate in facial, body and foot scrubs.Walnut shell is used by many, from the novice soap maker to the commercially distributed cosmetic lines. Element Shell will aid in formulating the custom grit sizes desired.

More aggressive formulations will use particle sizes as large as 20-40 mesh. The soft abrasive nature of walnut shell is still viable in flour sizes at 200 mesh and smaller for sensitive, fine scrubs.
cosmetic-walnutshellThe cosmetic grade of walnut shell is either ‘natural’ or ‘irradiated’ and has rounded edges (relative to an abrasive blasting grade) for a smoother feel. The irradiation process is performed with gamma rays and sterilizes the walnut shell to provide an indefinite shelf life (no micro-biological growth). ‘Natural’ product may require an additive in the formulation.

Walnut Shell has a significant range of natural skin care applications such as facial scrubs, skin cleansers, peeling creams and lotions, body exfoliants.

These shells are extremely hard and do not break down in the product. This property of walnut shells provides an effective natural body scrub coping very efficiently with even thick deposits of dead surface skin.

Most commonly, walnut shell can be used as an important exfoliating ingredient in any natural skin care range. Exfoliation requires removing oldest dead skin cells from the outermost surface of the skin. This treatment provides beauty, youthful appearance and health for many years.
