Bucket elevator is a very common lifting equipment. The choice of models is also limited by many factors. Once you choose the wrong model, it will bring a lot of trouble in the use process.

Firstly, chain, belt strip chain are selected as traction parts according to the nature type of materials;

Step 2: hopper type according to humidity viscosity of material. There are shallow barrel, deep barrel scale barrel to choose ;

The third step: according to the customer's specific delivery requirements, the appropriate elevator model;

Step 3: determine the lifting height of the material according to the actual basic conditions of the customer the lifting distance of the material, then determine the total height (the total height is the lifting height of the material plus the height of the head base);

Step 4: according to the size lifting height of the bucket elevator, the motor power required by the elevator can be selected through the relevant design table. If customers have special requirements, explosion-proof motor can be selected. Generally, the IP65 level is selected. It can meet the demand

Usually, the shape of the material directly determines the discharge method of the material. The general rule is that the powder material is discharged by centrifugal jet, the bulk material is discharged by gravity. Different discharge methods determine the hopper type used in bucket elevator. The difference is that centrifugal shot blasting mainly uses shallow bucket arc bucket, while gravity discharge requires deep bucket. When the type of hopper used in bucket elevator is different, the amount of material transported per unit time is also different.

The throughput of bucket elevator is a comprehensive parameter, which depends on hopper shape, hopper speed, material specific gravity, material characteristics hopper quantity.

The selection process of bucket elevator is as follows: material proportion → transmission mode (bucket elevator model) → material property → discharging mode → bucket elevator → lifting capacity of this series of bucket elevator → determination of model.

In addition to the choice of bucket elevator, the material is also very important. In addition to understanding the condition of stainless steel, other factors must be considered, such as corrosion, toughness properties of stainless steel, resources, price easy access.

The main purpose of choosing different stainless steel for bucket elevator is to solve all kinds of corrosion problems encountered in the elevator of century project. Corrosion is caused by the chemical electrochemical action between metal medium, corrosion resistance refers to the resistance of stainless steel. The ability of medium corrosion destruction. Please note the following:

1. The corrosion resistance standard is determined artificially. It is necessary to recognize it, use it, be bound by it. It is necessary to determine the specific corrosion resistance standard according to the specific use requirements. At present, the corrosion resistance of most stainless steels adopts grade 10 standard. To choose which level is the requirement of corrosion resistance, the characteristics of components (thin, thick, small) of bucket elevator as vertical conveying device must be considered.

2. Corrosion resistance is relative conditional. It is often said that stainless steel is stainless steel. Corrosion resistance refers to anti rust non corrosive, which refers to under certain conditions (medium, concentration, temperature, impurity, pressure, flow rate, etc. at certain time). Up to now, there is no stainless steel with corrosion resistance materials with corrosion resistance in any corrosive environment. The selection personnel must according to the specific service conditions. After selecting the grade of stainless steel, the user department must correctly use the characteristics of the selected stainless steel, which is reasonable. Choosing materials using them correctly can achieve the purpose of anti rust anti-corrosion.

In short, in the selection process of bucket elevator, it is generally necessary to refer to the technical indicators, such as lifting height, type of traction parts, model specification, hopper form, motor power, reducer model other technical indicators.
