The elevator — vertical belt conveyer — is designed to transport loose and lump material. It is produced of abrasion-resistant materials, therefore, it is especially suitable to transport highly abrasive materials.
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.
