Select the bucket elevator factors to be considered when
Select bucket elevators need to consider the following factors:
To consider the type of material is lifted and the characteristics such as the bulk density of the material, abrasive, corrosive, fluidity, angle of repose, moisture,
cohesiveness, loose, brittle, temperature, and other effects bucket hoist material handling properties.
The ability of transportation of materials needed to t / h expressed.
The particle size of materials. Maximum block size of the material, the average particle size and bulk material the percentage of the total amount of material.
Lift height or head and tail wheel center distance.
Operating conditions. Installed indoors or outdoors, environment, corrosive, humid and dry degree, the hottest and coldest temperatures, dust, pollution and so on.
Work system. Continuous or intermittent operation (ie, required number of hours worked per day).
Bucket elevator machine type selection
According to the characteristics of the material being transported to choose the type of bucket elevators. Material Flexible Roller Conveyor is powdered or block, with or without abrasive abrasive, the
material can withstand the centrifugal unloading; or a slower conveying speed necessary to avoid damage to the quality of material. Therefore, the right choice of
Bucket elevator, the characteristics of the material being transported is the single most important factor. Can be determined according to the material used in the hopper is
mounted on the tape or mounted on the chain, and can be determined from the table using centrifugal discharge bucket elevators or gravity discharge of the bucket elevator. To
On the particular materials can be agreed with the manufacturer selected type.
Choice of the hopper
Was promoted to the material characteristics of the hopper itself, the shape and structure design great impact. Select the hopper can be summarized as follows: For abrasive
materials, requiring the leading edge of the hopper has high strength along the mouth, in order to reduce the material hopper when the digging wear; against high moisture
products and illiquid
Materials using high edge along the mouth of the hopper, which can achieve the maximum lifting capacity; for easy suspension of the material, the hopper should be drilled hole
to facilitate deposition of materials; easily bonded to the materials or viscous, the underfloor The shallow powered roller conveyor circular hopper, the material in the hopper can be reduced dead
