Kuputika kwakaputika, kunowanzozivikanwa sekuti sandbever, iko kushanda kweanomanikidza kutsigira rwizi rwezvinhu zvakasimbisa kutarisana nechinhu chiri pasi pekumanikidza kuti hunyorove nzvimbo yakaoma, yakasviba kumeso, gadzira pasi kana kubvisa zvakasvibiswa zvepasirese. Yetsiyetsi yemagetsi, mweya inomanikidzirwa, kana vhiri remagetsi rinoshandiswa kurongedza zvinhu zvinoputika (zvinowanzonzi media). Kune akasiyana siyana echiitiko ichi, uchishandisa midhiya yakasiyana siyana; mamwe anonyanya kubiridzira, asi mamwe ari manyoro. Akanyanya kunyanyisa kupfurwa achiputika (nesimbi yakapfurwa) uye sandbaphakade (nejecha). Zvinyoro zvine mwero zvakasiyana zvinosanganisira girazi bead blasting (ine goridhe mikombe) uye midhiya kuputika nevhu-kumusoro epurasitiki stock kana walnut makobvu uye corncobs. Shanduro nyoro ndeye sodaborwa (ine bhata yekubheka). Uye zvakare, kune dzimwe nzira dzisiri nyore kubata kana dzisingabatsiri, dzakadai sekuputika kwemhepo uye kuputika kwechando.
Kuwedzera kuri kuda kwejecha kuputika kwemidziyo kunotyaira soko. Kuenderera mberi kwehunyanzvi, chirwere chemapapu senge silicosis inokonzerwa negwaro rejecha kuputika kwemabasa uye kukurumidza kwemaindasitiri ndiwo mafambiro akakosha ejecha kuputika kwemidziyo michina. Kutsiva kwebasa remanyorero kunatsiridza chibereko uye hunhu. Inhalation yeSilica, iyo yagara ichishandiswa sechinhu chakashata pazvinhu zvejecha blasting michina, inokonzeresa njodzi dzehutano dzakadai sedzungu uye zvimwe zvirwere zvemapapu. Simbi kuputika kwemidziyo inodzivirira kubata chero dambudziko remapapu, iro rinotarisirwa kukurudzira kukura kwemusika. Asia Pacific sandbaphakade michina yakadzora musika nekuda kwemutengo wakaderera uye kudiwa kukuru kwezvinhu izvi zvigadzirwa. China inofungidzirwa kuve iyo inonyanya kupa mari mubairo weAPAC. Europe sandbaphakade michina musika inotarisirwa kuwedzera pamusoro peiyo nguva yekufungidzira, ichiteverwa neNorth America.
