Li-nozzle tsa Venturi tse phatlohang habeli 

Blasting Nozzles hangata li hlaha ka libopeho tse peli tsa mantlha: straight bore le venturi, ka mefuta e mengata ea li-venturi nozzles.

Li-nozzles tsa Venturi hangata li arotsoe ka li-single-inlet venturi le li-nozzle tse kenang habeli.

Leqhubu le le leng la venturi ke leqhubu le tloaelehileng la venturi. E hlophisitsoe ka mokhoa o molelele o kopanyang oa tepe, o nang le karolo e khuts'oane e bataletseng e otlolohileng, e lateloang ke pheletso e telele e khelohang e atolohang ha u fihla pheletsong ea ho tsoa ea molomo. Sebopeho sena se etselitsoe ho hlahisa phello e potlakisang phallo ea moea haholo le likaroloana 'me e aba ka mokhoa o lekanang le abrasive holim'a paterone eohle ea ho phatloha, e fana ka sekhahla sa tlhahiso e kholo ea 40% ho feta molomo o otlolohileng oa bore.

The double venturi nozzle e ka nkoa e le li-nozzle tse peli tse latellanang tse nang le sekheo le masoba lipakeng ho lumella ho kenngoa ha moea oa sepakapaka karolong e ka tlaase ea noka ea molomo. Qetello ea ho tsoa e boetse e pharaletse ho feta nozzle e tloaelehileng ea venture blast. Li-nozzles tse peli tsa venturi li fana ka mokhoa o moholo oa 35% oa ho phatloha ho feta o tloaelehileng oa venturi blast nozzle e nang le tahlehelo e fokolang feela ea lebelo la abrasive. Ka ho fana ka mohlala o moholo oa ho phatloha, sekoti sa abrasive blast se thusa ho eketsa katleho e matla ea ho phatloha. E loketse mesebetsi moo ho hlokahalang mokhoa o pharalletseng oa ho phatloha.
