BUCKET ELEVATOR ELVA

ELVA ele­va­tor is a ver­ti­cal con­veyer with a con­tin­u­ous belt which carries trans­port buckets. The mate­r­ial is fed in the lower loading station and trans­ported up to the upper unload­ing station where it is dis­charged with gravity-cen­trifu­ga­tion. The mate­r­ial is fed in the buckets directly from the hopper. The scat­tered mate­r­ial is scoped by the buckets in the lower loading station. The belt with the buckets goes through a self-sup­port­ing shaft. There are guiding rollers that elim­i­nate vibra­tion of the belt in the ver­ti­cal direc­tion. The belt is stretched with a tension drum in the lower loading station. The drum posi­tion can be set with two tight­en­ing bolts. The driving drum is in the upper station and it is directly driven with a worm gear unit. The self-locking worm trans­mis­sion secures the ele­va­tor for spon­ta­neous move­ment of the belt with the loaded buckets. The ELVA ele­va­tor is made of mate­ri­als that resist abra­sive effects caused by the trans­ported mate­r­ial. The most exposed parts of the down and upper sta­tions are lined with abra­sion-resis­tant steel Hardox. Other parts are made of struc­tural steel.
