Gearbox in Bucket Elevator 

BK Series Bucket Elevator Gearbox ReducerChain bucket elevator is used to vertically lift powder, granular materials and small pieces of materials, and grind small pieces of materials, such as coal, cement, stone, sand, clay, ore, etc. Or other dry mortar for construction, chemical and food industries.

Bucket elevators are used to transport large quantities of bulk materials vertically to different heights without generating dust, and then dump them. The height to be overcome usually exceeds 200 meters. The weight to move is enormous.

The bearing element in bucket elevator is the center or double chain strand, chain link chain or belt connecting the bucket. The drive is in the upper station.

The characteristics of the drives specified for these applications are similar to those of the jerk belt conveyors. Bucket elevators require relatively high input power.

Due to the high starting power, the driving device must be soft started, which is realized through the fluid coupling in the transmission system.

Bevel and helical gear units are commonly used as single or double drives on base frames or oscillating bases.

Recommended options for high capacity bucket elevators

ever-power industrial gear units are based on the
modular system from ever-power and provide many individual options such as:

BK Series Bucket Elevator Gearbox Reducer

  1. Axial fan
    High performance axial fan is directly installed on the drive shaft to provide high cooling power and heat reserve.
  2. Base frame/motor rocker arm
    All mechanical and electrical components are mounted on the motor rocker arm or motor frame, which simplifies the installation of the drive train.
  3. Hydraulic fluid coupling
    The hydraulic coupler allows the belt to start slowly, preventing excessive tension on the belt and high torque in the gear unit. In addition, it reduces the starting current.
  4. Backward stop
    The back stop prevents backflow of the inclined conveyor belt. All rear stops are mounted externally and can be replaced without removing the gear unit. The rear stop is also lubricated with gear oil.
  5. Auxiliary drive
    Auxiliary drive, including overrunning clutch
    Operate the system at low speed or "inch" final drive.
  6. Taconite seal
    Taconite seals prevent damage to the shaft seal ring in an abrasive or dusty environment. It consists of a labyrinth seal that can be re lubricated to prevent abrasive dust from entering the seal
