According to the characteristics of material selection of the appropriate hoist, is to ensure safe and reliable and efficient transportation of the necessary conditions. For the grinding of strong, material temperature of 100 ° C in the following powder or small granular material preferred TDG series of high-performance steel wire rope bucket elevator; for the bulk material will use NE Ⅱ series of chain bucket elevator bucket; For the material moist, easy to agglomerate the material can only use TH series (zh hopper) of the chain bucket elevator; for general abrasive or temperature greater than 100 ° C powder or small granular material, should use NSE Ⅱ Series plate chain bucket elevator.
