How Much do You Know the Reasons of Buckets Falling of Bucket Elevator?

1.Too much feeding. It will cause material blocking in the machine, and increase elevator resistance. Feeding too much is the main reason of buckets’ falling. Stop the machine immediately in the situation, and take out spile under frame. Discharge material in engine base, replace new buckets, and then start to production. Meanwhile, decrease feeding volume uniformly.

2.The position of inlet is too low. In general, bucket serve materials from inlet automatically when bucket elevator is in operation. If the position of inlet is too low, buckets may have no time to serve materials and then most materials into engine base. However, materials are lump, which is easy to cause the deformation and falling. Inlet position should be above the center line of return pulley.

3.Bad material of bucket with limited strength. Buckets are the bearing parts of bucket elevator, and have high requirements on buckets materials. Select material with high strength when install. In general, buckets are welded or pressed by common steel plate or galvanized plates, and edges should be folded or involved in galvanized wire to enhance the strength of buckets.

4.Haven’t discharging materials in engine base when starting up. There is always down phenomenon caused by power failure or other reason in operation. And when re-start, buckets are easy falling as too much impact if no discharging materials in engine base. Therefore, must discharge materials in engine base to avoid buckets falling. In addition, check the connection of buckets and belt regular. If screw is loose or falling, or buckets are damaged, check and replace in time to avoid more accidents.

5 Things to Know about the Mechanized Silo

1.Classification: agricultural silo and industrial silo  Agricultural silo:Used to store food, feed and other granular and powdered materials  Industrial silo:Used to store coke, cement, salt, sugar and other bulk materials
2.Importance:Mechanized silo generally cost about a third higher than mechanical room of the warehouse cost, but it can shorten the material loading and unloading process, reduce the operation and maintenance costs, eliminate heavy bags of homework.So it is advantageous to the mechanization, automation of operation, thus becoming one of the main forms of granary.

3.Installation:The discharging hopper is always installed at the bottom of the mechanized silo, the upstream is equipped with conveying equipment. When loading materials, the bulk materials will be lifted by the bucket elevator and then discharged into the horizontal belt conveyor, the belt conveyor conveys the bulk material to the silo. When discharging material, the bulk materials will be discharged to the downstream through the dump hopper,then conveyed by the horizontal belt conveyor to other place.

4.Planar shape classification:Silo plane is divided into square, rectangle, polygon and round shape, etc.Due to the circular silo wall force is reasonable, when storing materials single species or reserves is small, it should arrange with independent warehouse or a single row layout. When storing materials or reserves larger species,it should arrange in groups.The total length of the cylinder group of storehouse is generally not more than 60 meters, the total length of the square of storehouse is generally not more than 40 meters.

5.Problems: Appropriate measures should be taken when there is large silo group length or wall force and complex ground situation, such as setting a expansion joint in order to eliminate the shrinkage stress of concrete and temperature stress effects, setting a settlement joint to avoid uneven settlement influence due to huge load difference from different parts of the structure itself or the bearing capacity of foundation soil have obvious differences, setting an earthquake cracks in order to reduce earthquake damage.
