Vertical vibration screw feeder is a new type of vertical vibration
conveying equipment. This machine can convey all granule, block,
powder of solid materials (small viscosity). It is widely used in
mining, metallurgy, machinery, building materials, chemical,
rubber, medicine, electricity, grain, food industries of block,
powder and short fibrous solid materials lifting. This kind of
elevator can complete drying and cooling of the materials while
It has slotted and closed two structures. And we can design
elevator used for material particle classification, for inflammable
and explosive material and for cooling down material according to
different technological requirements.
This series of elevator adopt vibration motor as the vibration
source. Two sets of vibration motors with the same model which are
fixed on the llifting slot are installed centerline cross at an
angle , and do the opposite direction synchronous rotation. When
eccentric block equiped in the vibration motor rotating, the
centrifugal force components generated by the instantaneous
position do the reciprocating motion along the casting direction,
making the whole body supported on shock absorber vibrate
constantly. Material is thrown up in the lifting slot and do the
upward movement at the same time. After falling into the trough,
the material start to be thrown up. At this time, it can make raw
material and air a good contact, and also play a role in thermal
1. Vibration source: Cross shaft type and parallel shaft type
2. Seat-type and suspended type
1. Cover a small area, simple and reasonable structure.
2. Small power consumption, no noise, easy maintenance.
3. Enclosed lifting effectively prevents the dust and harmful gas
pollution to the working environment.
