1. Introduction
Bucket elevator is designed to transport powder, granular and lump materials, which also can lift
abrasive materials, such as fly ash, slag, limestone, cement slurry, cement clinker, cement, coal, dry clay,
etc., it has an opening bin below for storing material, when the motor driving the endless plate chain
(chain or belt) through the chute, the hopper fixed in the chain of plate (chain or belt) bring the material to
the discharging opening, in this way it continuously convey the material.
Ring chain Bucket Elevator is applied in the vertical conveying of abrasive powder, granular and small
lump materials, such as grain, coal, cement and crushed ore, etc., and its transportation height can
reach to 40m. The bucket chains are characterized by simple structure, stable operation and hybrid or
gravity discharge. The wheel rim uses combination sprocket, and it is easy to replace and has been
specially treated to ensure a long service life. The under part is equipped by gravity automatic tensioning
device, so that it can maintain a constant tension to avoid slipping off the chain. The material
temperature can not exceed 250 °C.

2. Advantages
 Excellent sealing, less environmental pollution.
 Easy Operation and maintenance, less wearing parts.
 Energy conservation and less maintenance ensure the machine a very low cost.
 Advanced design principle has ensured the reliability of machine operation.
 High accuracy. The housing case is of good rigidity and beautiful appearance by the edge
folding and intermediate beading.
 Small size. Compared with other machines which have the same lifting capacity, size of this
machine is smaller.
 Transmission capacity. The series hoist NE15 ~ NE800 a variety of specifications.
3. Working Principle
Hopper scoops up materials from the stone bucket below, then is lifted to the top with the conveyor
belt or chain, and next it is downward rolled over bypass the wheel on the top and the materials are
dumped into the accept slot now by bucket chain or hoist conveyor, and the whole process is over.
The driving band of bucket elevator with driver is commonly made of rubber, and it is installed below
or above the drive roller and the divert roller. The chain-drive bucket elevator is generally equipped
with two parallel transmission chain, on which above or below is a drive sprocket and a divert
sprocket. Continuous Chain or Belt Bucket Elevator for Cement are generally equipped with chassis
to prevent the dust
flying into the bucket
elevator.

8. Troubleshooting
 Motor can start none loaded. Problem analysis as following:
a. Supply not connected;
b. Button not functions with insensitive touch.
Measures: Connect supply, repair related electrical members;
 Abnormal noise occurs during operation. The equipment must be stopped at once to see whether
any ware parts loosening or big lump blocking. Cleaning and alteration should be made when above
problems found.
 If continuous undue electric current found, overload or material blocking may occur.
 The equipment should stop first. If overload found, the capacity should be lowered; If material
blocking found, cleaning should be made and the reason should be traced.
 If violent vibration at lower section of the equipment, one should check whether take-up device
provide due tension. If no, adjustment should be made to the take-up spacing to restore the bucket
elevator to the normal tension.
