Isizathu sokuchezuka kokufana phakathi komugqa omaphakathi wohlaka lokuthutha ibhande kanye nomugqa omaphakathi oqondile wesithumeli sebhande akufanele seqe u-3mm.Isizathu sokuphambuka kokucaba kwefreyimu ephakathi nendawo phansi asikho ngaphezu kuka-0.3%.
Ukuhlanganiswa kwefreyimu ephakathi ye-conveyor yebhande kuzohlangabezana nezidingo ezilandelayo:
(1) Isizathu sokuchezuka kokuhambisana kwefreyimu ephakathi yesithuthi sebhande endaweni ehambisanayo yentambo yokuqondisa intambo akumele kudlule u-0.1% wobude;
(2) Ukuchezuka okungaphezulu, okuphansi, nokuphakama kwemithungo yohlaka olumaphakathi lwesithuthi sebhande akufanele kudlule i-1 mm;
(3) Iphutha lesikhawu L sefreyimu emaphakathi yesithuthi sebhande akufanele lidlule ku-±1.5mm, futhi umehluko wokuphakama olinganiselwe akufanele udlule u-0.2% wesikhawu;
(4) Isizathu sokuchezuka kokuhambisana kwerola eliyisivila elinqamula umugqa omaphakathi ukuya kulayini omaphakathi oqondile wesixhumi sebhande akufanele seqe ku-3 mm.

Isikhundla se-roller eqinisayo ngemuva kokuxhunywa kwesidlulisi sebhande, ngokuya ngendlela yedivayisi eqinisayo, ingqikithi yebhande, ubude bebhande, kanye nesistimu yokubhuleka kucaciswe ngokucacile, futhi ngokuvamile kufanele kuhlangabezane nezidingo ezilandelayo. :
(1) Emishinini yokuqinisa eqondile noma yohlobo lwemoto, i-stroke exegayo eya phambili akufanele ibe ngaphansi kuka-400mm, kanye ne-stroke eqinisa ngemuva.
Kufanele kube izikhathi ezingu-1.5 ~ 5 ze-stroke exegayo eya phambili (lapho ubude be-polyester, i-canvas belt core noma i-conveyor yebhande idlula ama-200m, futhi lapho injini iqalwa ngokuqondile futhi kunesistimu yokubhuleka i-stroke, i-stroke enkulu yokuqinisa kufanele ibe ekhethiwe).
(2) Ngomshini wokucindezela okuvunguzayo wesithuthi sebhande, ukushaywa okuya phambili okuxegayo akufanele kube ngaphansi kuka-100 mm.
(3) Indawo yokuhlanza i-scraper yedivayisi yokuhlanza kufanele ixhumane nebhande lokuthutha, futhi ubude bokuxhumana akufanele bube ngaphansi kwama-85% wobubanzi bebhande.
Ngemuva kokuthi i-idler roller isigxilile kuhlaka lwe-conveyor yebhande, kufanele ijikeleze ngokuguquguqukayo futhi ingalungiswa namawasha.I-axial cylindricity ye-idler roller eya emgqeni wayo ophakathi ngemva kokufakwa: lapho i-diameter ye-idler D<800Mm, ukubekezelela kwayo kobukhulu kungu-0.60mm;lapho D>800Mm, ukubekezelelana yayo ntathu kuyinto 1.00mm.Ngemva kokuthi i-idler isigxilile kuhlaka, ukubekezelela kobukhulu obuqondile phakathi komugqa omaphakathi nomugqa omaphakathi wohlaka kungu-0.2%.Indiza evundlile yesikhungo se-symmetry ye-idler kufanele idlule umugqa omaphakathi wohlaka, futhi ukubekezelelana kobukhulu bayo obuyi-symmetry ngu-6 mm.
