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 graphite 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, cleanliness, and will not produce pollution on the material, the use of a long time, but the relatively high cost.
