Polyurethane Screening System
Makanema owonera ndi gawo lofunikira pazida zowunikira.Pamene chophimba chogwedeza chikugwedezeka, kupyolera mu maonekedwe osiyanasiyana ndi kukula kwa geometrical ndi pansi pa machitidwe a mphamvu zakunja, zopangira zidzalekanitsidwa ndikukwaniritsa cholinga cholemba.Mitundu yonse yazinthu zakuthupi, kapangidwe kosiyana ndi zinthu zowonera gulu kapena kukanikizana ndi magawo osiyanasiyana amakina owonera ali ndi mphamvu pazithunzi, magwiridwe antchito, kuthamanga komanso moyo.Zida zosiyanasiyana, malo osiyanasiyana, ziyenera kusankha zowonera zosiyanasiyana kuti zikwaniritse bwino zenera.
Kutengera ndi zida zosiyanasiyana, zofunikira komanso momwe zinthu ziliri, zowonera zitha kulekanitsidwa ndi mndandanda pansipa
1.Modular mndandanda
2.Tension series
3.Panel mndandanda
Kulumikizana ndi zida nthawi zambiri kumagawidwa kukhala: kulumikizana kwa mosaic, kulumikizana kwa bawuti, kulumikizana kwa bar, kulumikiza mbedza ndi zina zotero.
Ntchito zamigodi
1.Kugaya kale miyala
2.Pre- mulu leach
3.High kalasi yachitsulo miyala yachitsulo
4.Mill zowonetsera zotulutsa
5.Dense media circuits
6.Control screening - kuchotsa bwino
Dongosolo lowunikira la polyurethane limagwiritsa ntchito mokwanira kukana kwamphamvu kwa polyurethane elastomer, kuwonetsa kulimba kwambiri, kutalika kwakukulu komanso kulimba kwambiri pakulimba.Polyurethane ndi chinthu choyenera kuwunikira.Amapereka kukana kwa abrasion ndipo amatha kusinthasintha kuti asamangidwe.Imagwiranso ntchito mwangwiro pazowunikira zonyowa komanso zowuma.Machitidwe a modular amatha kupanga kukula, mawonekedwe ndi mphamvu iliyonse.Zosinthidwa pamakina aliwonse ndi kasitomala kuti zikhale zosinthika ndi machitidwe ena.Dongosololi ndilabwino pakuwunika ndikuchotsa madzi.Mapanelo a polyurethane amathanso kusinthidwa mwachangu popanda kufunikira kwa chidziwitso chaukadaulo kapena zida.Pali mitundu yosiyanasiyana ya zowonjezera kuti zitheke kugwiritsidwa ntchito pamitundu yambiri yamapulogalamu.Makamaka, zowonetsera zathu zamphamvu za polyurethane zomangidwa ndi chitsulo cholimbitsa chingwe.Njira yopangira iyi imawonjezera kukana kwa polyurethane kupsinjika ndi katundu potengera kupsinjika.Kusinthasintha ndikoyenera kugwiritsidwa ntchito powunika zinthu zomwe zimapangidwira pamwamba kapena pamphepo pakuwunika.Amapangidwa molingana ndi kukula kulikonse kapena mawonekedwe kuti athe kukwanira makina aliwonse.Makulidwe osinthidwa ndi momwe amagwirira ntchito amapezekanso mukapempha.

Mawonekedwe
1.Good shock mayamwidwe
2.Kukana kwamafuta
3.Kutsika kwa kutentha kwapansi
4.Kutentha kukana kukalamba
5.Kukana kwa dzimbiri
6.Kutchinjiriza kwamagetsi
7.Kuvala kukana
8.Kudziyeretsa
9.Kupulumutsa mphamvu
