TH series of bucket elevator（斗式提升机） is the upgrading product of the HL-buckeyes elevator. Compared with HL type. TH type of elevator possesses the advantages of tager transmission capacity，higher degree，more stable and reliable operation and longer life and the structure and feature of TH series of bucket elevator（斗式提升机）.
(1) The capacity of the bucket closes to the actual volume of filing, plus the speed increases, the conveying capacity increases nearly doubled than that of the same bucket for the HL as follows.
(2) Top and bottom sprockets use assembly structure to facilitate the replacement flange and low maintenance costs.
(3) The lower part uses tensioning device with a heavy hammer leveraged style that automatically maintain a constant tension, avold slipping or falling off linked chain so that it is conducive to normal operation.
(4) Traction is linked to high-intensity ring. After heat treatment, it has a high tensile strength and wares resistance and therefore it keep a long life
The model of material bucket and material-handling method of TH series of bucket elevator（斗式提升机）.
The conveyor bucket comprises two bucket type: ZH medium-deep bucket is generally applied for the distribution of wet, stick materials that are so difficult to thrown out, such as Greensand, fertilizer, alkali powder, clay, etc. SH deep bucket is generally applied for distribution of dry, loose materials and materials that are easily thrown out, such as gravel, lump coal , cement raw materials, cement and slag ,etc.
The conveyor bucket is for machine-loading, mixed or gravity unloading, It is applied to transfer small pieces of powdery and low pondering type of materials of which packing density is less than 1.5t/m3 and humidity is not more than 250℃, The main technical parameters are shown in the following label.
