Vertical Bucket Elevator With ISO9001: 14000 Certified

Description of Bucket elevator:

Vertical Bucket elevator with large throughput, great enhancing-height, stable and reliable operation, long life and other significant advantages. Hybrid-type or gravity discharge,  earth-type loading. Application to transport packing density of less than 1.5t/m3, easy to take out the powder, granular, small block of low-mill cut materials, such as coal, cement ,gravel ,sand fertilizer, food and so on. Delivery temperature of the material does not exceed 250°C. The elevator spare parts include chain, bucket and so on.

Bucket Elevator Structure:

1. Buckets to contain the material;
2. A belt to carry the buckets and transmit the pull;
3. Means to drive the belt;
4. Accessories for loading the buckets or picking up the material, for receiving the discharged material, for maintaining the belt tension and for enclosing and protecting the elevator.

Working Principle of Bucket Elevators:

A centrifugal discharge elevator may be vertical or inclined. Vertical elevators depend entirely on the action of centrifugal force to get the material into the discharge chute and must be run at speeds relatively high. Inclined elevators with buckets spaced apart or set close together may have the discharge chute set partly under the head pulley. Since they don't depend entirely on the centrifugal force to put the material into the chute, the speed may be relatively lower.
Nearly all centrifugal discharge elevators have spaced buckets with rounded bottoms. They pick up their load from a boot, a pit, or a pile of material at the foot pulley.
The buckets can be also triangular in cross section and set close to on the belt with little or no clearance between them. This is a continuous bucket elevator. Its main use is to carry difficult materials at slow speed.
Early bucket elevators used a flat chain with small, steel buckets attached every few inches. Current construction uses a rubber belt with plastic buckets. Pulleys several feet in diameter are used at the top and bottom. The top pulley is driven by an electric motor.
The bucket elevator is the enabling technology that permitted the construction of grain elevators. A diverter at the top of the elevator allows the grain to be sent to the chosen bin.

Features and benetits of Bucket Elevator:

1. Low driving power, inflow feeding, induction unloading, high-volume hopper intensive arrangement. There is almost no feed back and excavating circumstance when materials are lifted, so invalid power is little.
2. Wide lifting range, little materials type and property requirement can not only lift general powder and granule materials, but also lift high polishing materials. Sound seal and little circumstance pollution.
3. Good running reliability, the advanced design principle and handling method assure reliability of whole machine running, the non-fault time exceed 20 thousand hours. Stable running make it reach higher lifting height.
4. The life is long, inflow feeding, non excavating with hopper and there is few extrusion and collision circumstance between materials. There is little materials sprinking during feeding and discharging to reduce machinery abrasion.
