China high quality Steel U type auger cement screw conveyor supplier

1. If the length of U-shaped screw conveyor is less than 35m  it is a single-axis driving screw.

2. If the length of U-shaped screw conveyor is greater than 35m  it is a two-axis driving screw.

According to the screw conveyor middle hanger bearing type

1. M1- is a rolling bearing  adopts type 80000 sealed bearing  and the shaft cap has a dust-proof sealing structure. It is commonly used in areas where it is difficult to refuel  no refueling  or oil contaminates the material. The sealing effect is good  and the hanging shaft has a long service life. Temperature of conveying material ≤ 80°C.

2. M2- is a sliding bearing  equipped with a dustproof sealing device  a cast copper tile  an alloy wear-resistant cast iron tile  and a copper-based grate less oil-lubricated tile. Commonly used in the transmission of material temperature is relatively high (t ≥ 80 °C) or transport water containing larger materials.

According to screw conveyor material classification

1. Ordinary carbon steel U-shaped screw conveyors - Mainly used in industries where cement  coal  stone  etc. wear out  and there are no special requirements for materials.

2  stainless steel U-shaped screw conveyor - mainly applicable to food  chemical  food and other industries that have requirements for the delivery environment  cleancirc; and will not produce pollution on the material  the use of a long time  but the relatively high cost.
