Bucket elevators are used to transport powdered or granular materials vertically or obliquely. Its lifting height can reach 30 meters, and the common range is generally 12 to 20 meters. The conveying capacity is below 300 tons/hour.

There are many classification methods for bucket elevators. According to different installation methods, they can be divided into vertical and inclined. According to different unloading characteristics, they can be divided into centrifugal, centrifugal, gravity and gravity. According to different loading characteristics, they can be divided into different types. The drawing type (a in the figure) and the inflow type (b in the figure) can be divided into belt type and chain type according to different traction member types; depending on the hopper form, it can be divided into deep bucket type, shallow bucket type, triangle bucket or Trapezoidal bucket. 
A selection The commonly used bucket elevators in China are D, HL, PL, ZL and other four types of vertical bucket elevators.
In order to meet different usage requirements, the four commonly used bucket elevators have different manufacturing methods and methods.
B Power calculation (1) The approximate calculation of the bucket hoist shaft power is as follows:
Q———delivery amount, t/h;
H———lift height, m;
V———speed increase, m/s;
K 1 , K 2 ———The coefficient related to the structure type and lifting amount of the hoist.
(2) Motor power:
K 3 ———Power reserve factor: related to the height of the hoist, K 3 = 1.45 when H<10m, K 3 =1.25 when 10<H<20m, K 3 =1.15 when H>20m;
η 1 ———The transmission efficiency of the reducer is generally η 1 =0.94;
η 2 ——— V-belt or open gear transmission efficiency, for V-belt η 2 =0.96, for open gear η 2 =0.93
