Bucket elevators are widely used systems for vertical transport of bulk, dry, wet and even liquid materials. It is designed with various options of height, speed and constructive details depending on the type of materials to be transported. It is constructed by pieces or unit to allow to define efficiently the needed height. A bucket elevator consists of head hood, engine, drive and pulley, discharge spout, casing, belt, bucket, clean outdoors, tensioning device, boot inlet hopper and boot.
There are two types of load input which are directly to the input hopper or by digging. The method of directly to the input hopper is used for transport of abrasive and big size materials and it’s chain/belt travelling speed is low. For digging method, it is used for transport of materials that offer no resistance to extraction, like fine grain and dusty materials.

There are few types of discharge which are centrifugal, gravity or continuous and positive. Centrifugal discharge is the most common discharge option. It has great travelling speed of 1.2 and 1.4 m/s. It’s loading is carried by dredging the material at the bottom of the elevator. The separation distance between the buckets is 2 to 3 times the bucket height. For gravity or continuous discharge, it’s travelling speed is lower which are 0.5 and 1.0 m/s. It is taken advantage of self-weight. There are two classification of this discharge, free gravity and forced. The free gravity is necessary to change the free branch line or incline the bucket whereas forces are where the buckets are situated one after the other without separation between them. The discharge takes place due to gravity by means of the lower part of the preceding buckets that acts as a discharge spout. The positive discharge is similar to the gravity elevator safe that buckets are fitted at the edge with two cords. Bucket speed is low are appropriate for light, aired and sticky materials.
