M'munda wa zida za Drum zowombera zida zamakina, zofunika kwambiri ndizowombera ndikuphulitsa mchenga. Kuphulika kwa mfuti makamaka kumatanthauza makina owombera, pomwe kuphulika kwa mchenga kumatanthauza zida zophulitsira mchenga. Otsatirawa akudziwitsani kusiyana komwe kulipo pakati pakuphulika ndikuwombera mchenga.
Kuphulika kwa Shot ndi dzina la njira yopangira makina padziko lapansi. Cholinga chake ndikuti galimoto imayendetsa thupi la wopangitsa kuti lizungulira. Mwa zochita za mphamvu ya centrifugal, mulifupi wina wa projectile umaponyedwa pansi pa cholembedwacho, kotero kuti pamwamba pa cholembedwacho chimafika poyipa. Sinthani moyo wautumiki pantchito.
Sandb ever (sanding) ndi mtundu wa ntchito yogwiritsa ntchito mpweya wothinikizidwa ngati mphamvu yokankhira owonjezera kumtunda kwa chosakira. Makamaka, imagwiritsa ntchito mpweya wothinikizidwa, madzi othinana kwambiri, nthunzi, etc. kuyendetsa otaya oyera kuti ayeretse, kulimbitsa, kudula ndi kutulutsa pamwamba pa malo ogwiritsira ntchito. Sandbever ndiofala pakusintha mawonekedwe kapena dziko, koma njirayi ndiyosachedwa ndipo siziwoneka mosavuta.
Cholinga chowombera ndi kuwulutsa kwa mchenga chinthunzi chogwirira ntchitoyi ndikukonzekera dongosolo lotsatira, osati kungowonetsetsa zofunikira za njirayi, komanso kuonetsetsa kuti malo ogwirira ntchito ali ofanana momwe mungathere pamankhwala othandizira, ndi mawonekedwe kuwombera kuwombera kumalimbitsa makina ogwiritsira ntchito, ndipo momwe zimadziwikira Mwachidziwikire, momwe zilili, kupindika kwa sandb sizodziwika. Nthawi zambiri, kuwunjika peyala ndi mpira wachitsulo yaying'ono, ndipo kuphulika kwa mchenga kumakhala mchenga wa quartz. Sandb ever imangokhala ntchito yamanja, ndipo kuwombera kuwombera kumangodziwikiratu komanso sikulipikidwe; kutsitsi kumakhazikitsidwa ndi mpweya wothinikizidwa ngati mphamvu yothira mchenga kapena ma pellets pamwamba pa zinthu kuti zitheke komanso kuuma. Kuponya ndi njira ya centrifugal mphamvu yopangidwa pomwe pellet imazunguliridwa mofulumira kwambiri, zomwe zimakhudza nkhope ya zinthu kuti zitheke kuchotsedwa komanso kukwiya; kaya yaphulika kapena ngati kuphulika kwa mchenga, chogwirirachi chitha kutsukidwa ndikuwonongeka.
