Ground-up walnut shells go into products used for metal cleaning and polishing, oil well drilling, paint and explosives. They are used to clean jet engines, electronic circuit boards, ships and auto gear systems. The paint industry uses the shells to make plaster-effect paints. The ground-up shell also can be used as a natural stain. The shells are used as filler in dynamite.

Walnut shell filters are simple and reliable, compared to many filtration techniques designed to remove oil contaminants and suspended solids from water. There are no chemicals, very few moving parts and the walnut shell filter media can be used over and over again. Walnut shell filters can take water with up to 100 parts per million of contaminants and reduce this level to under 5 parts per million. This is cleaner than normal drinking water.

These unique natural filters have applications in the chemical, petrochemical, metal working and power generation industries, but they are especially valuable in offshore drilling applications. The great thing about the latest generation of Walnut Shell Filters is that they are small and light enough to be installed on a ship.

Couple this with the fact that walnut shell filters can be specifically designed for offshore use to remove more than 98 percent of the contaminants passing through it, and it has an amazing large scale application. These filters can be used to treat oil field produced water, refinery wastewater, and other types of wastewater.

Walnut shell also serves as an environmentally safe and effective filtration media when separating crude oil from water. 

The dynamite industry uses ground Walnut shell as filler in dynamite.  Walnut shell flour is used as a filler and adhesive ingredient in the manufacture of plywood-and as filler mixed with resins to create cold castings.  (Walnut Shell) is an effective means of Controlling Lost Circulation. The fine grade of walnut shell can be circulated through a 20 Mesh Shale Shaker Screen. Coarse grade will be removed from the system unless the solid control / removal equipment is by past.

“What are the applications of walnut shell (NUT PLUG)in BLASTING?” The combination of angular design, lightweight and relative softness makes walnut shell blast media an excellent choice for the deburring, cleaning, deflashing or stripping of softer substrates such as plastics, wood, fiberglass, aluminum and various composite materials. The walnut blasting process is compatible with air and wheel blasting as well as tumbling. Specific walnut shell media blasting applications include: a) Enhancing the porosity of grinding wheel and ceramics in burn-out applications b) Stripping and cleaning of castings and moldings c) Deflating electronic components d) Deburring plastics and die castings e) Cleaning of metallic surfaces on automobiles, boats, bridges and buildings f) Cleanout of aircraft engines and steam turbines And there are many advantages that we can count for the “walnut shell blasting” and we will soon, provide for you on our website.

Walnut Shell” Major Benefits and Features: Walnut Shell Grit: is a blast cleaning media for removal of paint, flash, burrs and other flaws in plastic and rubber molding, aluminum and zinc die casting and the electronics industry. It is used as a sand replacement for paint removal, graffiti removal and general cleaning in restoration of buildings, bridges and outdoor statuary. Walnut Shell is used for aircraft engine clean out and for cleaning steam turbines. Some features of it is as below: ** Pure and safe ** Hygienically made ** Fresh and natural ** Safe packaging ** Nominal costs ** Inert additive ** Excellent result ** Unaffected by pH

Nut Plug (Walnut shell / Nutshell) cellulose is an effective lost circulation treating material. It has a granular shape, and can be used in a blend of various sizes (fine, medium, and coarse) to prevent lost circulation or regain returns once losses begin. Nut Plug hulls are available in two types of material: pecan and walnut. The walnut hulls have greater strength. Treating levels depend on the severity of the losses and type of formation where the losses occur. Nut Plug material may be mixed with other shaped materials to provide a wide variation for optimum control. It may be used to treat the entire system or added as a concentrated pill. Nut Plug material can be added to other special slurries, such as high fluid‐loss squeezes, to assist in forming strong bridging plugs. Typical treating levels for preventative measures are from 2 to 5 lb/bbl (5.7 to 14.2 kg/m3), and for more severe losses use 5 to 25 lb/bbl (14.2 to 71.3 kg/m3). NUT PLUG material has a high compressive strength, and can be used, if desired, as a lubricant.NUT PLUG
