Screw conveyor classification

1

According to screw conveyor drive classification

1. If t he 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, a nd 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. S tainless 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.
