Cov ntawv tshuaj ntsuam ib txwm ua los ntawm cov hlau, tab sis polyurethane maj mam dhau los ua ntau dua nyob rau xyoo pua 21st. Xyoo 2020, herringbone screen plates siv nyob rau hauv metallurgical mines txhim kho kev tshuaj ntsuam xyuas los ntawm 20% los ntawm kev kho mesh zoo (45℃kaum sab xis) thiab daim ntawv thov ntawm hnav-cov pa roj carbon steel.
Cov ntawv loj tshaj plaws ntawm cov ntawv tshuaj ntsuam muaj ib lub thav duab ntoo thiab ib qho screen ua los ntawm cov plaub hau zoo. Qhov ntxov tshaj plaws sau tseg siv cov hlau mesh hauv cov ntawv tshuaj ntsuam hnub rov qab mus rau 1556 rau kev ua ore. Xyoo 1838, lub tuam txhab German Louis Hermann tau pib tshwj xeeb hauv kev tsim cov phiaj xwm kev lag luam, txhawb kev loj hlob ntawm kev tshuaj ntsuam thev naus laus zis.
Qhov ntxov tshaj plaws polyurethane tshuaj ntsuam daim hlau tau tsim nyob rau hauv nruab nrab-1960s thiab maj mam txhim kho nyob rau hauv lub xyoo caum tom ntej, dhau los ua ib qho tseem ceeb kev taw qhia nyob rau hauv txoj kev loj hlob ntawm cov tshuaj ntsuam phaj technology.
Hauv xyoo 2020, polyurethane npo phaj thev naus laus zis txuas ntxiv tsim kho tshiab. Piv txwv li, nyob nruab nrab ntawm 2025 thiab 2026, tshiab patented technologies tshwm sim los txhim kho kev tsim khoom zoo (xws li tilting automated pouring kom tshem tawm cov npuas npuas) thiab txhim kho functionality (xws li tus kheej- ntxuav arc cov ntxaij vab tshaus haum rau ntub thiab nplaum cov ntaub ntawv), ntxiv rau kev txhim kho qhov zoo ntawm daim ntawv thov kev ua tau zoo.
