Chigoba cha Walnut grit ndi chinthu cholimba cha ulusi wopangidwa kuchokera pansi kapena zipolopolo za mtedza wosweka. Akagwiritsidwa ntchito ngati chowulutsira, walnut shell grit ndi yolimba kwambiri, yokhota komanso yamitundu yambiri, komabe imatengedwa ngati 'soft abrasive'. Chigoba cha Walnut blasting grit ndi njira yabwino kwambiri yosinthira mchenga (silica yaulere) kuti musapumedwe ndi vuto la thanzi.
Kuyeretsa ndi kuphulika kwa chipolopolo cha mtedza kumakhala kothandiza kwambiri pamene pamwamba pa gawo lapansi pansi pa utoto, dothi, mafuta, sikelo, mpweya, ndi zina zotero, ziyenera kukhala zosasinthika kapena zosawonongeka. Chigoba cha Walnut grit chimatha kugwiritsidwa ntchito ngati chophatikizira chofewa pochotsa zinthu zakunja kapena zokutira pamalopo popanda kupaka, kukanda kapena kuwononga malo oyeretsedwa.
Mukagwiritsidwa ntchito ndi zida zoyenera zophulitsira zipolopolo za mtedza, zoyeretsera zomwe zimachitika nthawi zambiri zimaphatikizira kuvula mapanelo agalimoto ndi magalimoto, kuyeretsa nkhungu zosalimba, kupukuta zodzikongoletsera, zida zamagetsi ndi ma mota amagetsi musanabwezeretse, kutsitsa mapulasitiki ndi kupukuta mawotchi. Akagwiritsidwa ntchito ngati njira yoyeretsera, grit ya walnuts imachotsa utoto, kuwala, ma burrs ndi zolakwika zina mu pulasitiki ndi mphira, aluminium ndi zinc kufa-casting ndi mafakitale amagetsi. Chipolopolo cha Walnut chingalowe m'malo mwa mchenga pochotsa utoto, kuchotsa graffiti ndikuyeretsa mwachisawawa pokonzanso nyumba, milatho ndi ziboliboli zakunja. Chipolopolo cha Walnut chimagwiritsidwanso ntchito kuyeretsa injini zandege ndi ma turbines a nthunzi.
