According to the type of intermediate hanging bearing of screw conveyor
1. M1- is a rolling suspension bearing. It adopts 80000 type sealed bearing. There is a dust-proof sealing structure on the shaft cover. The temperature of conveying material is less than or equal to 80℃.
2. M2- is a sliding hanger bearing with dust-proof sealing device, cast copper tile, alloy wear-resistant cast iron tile, and copper-based graphite oil-less lubricating tile. Commonly used in conveying materials with relatively high temperatures (t≥80℃) or conveying materials with large water content.
Classification by screw conveyor material
1. Ordinary carbon steel U-shaped screw conveyor - mainly suitable for cement, coal, stone, and other industries with large wear and no special requirements for materials.
2. Stainless steel U-shaped screw conveyor - mainly suitable for industries that have requirements on the conveying environment such as grain, chemical industry, food, etc., with high cleanliness, no pollution to materials, long service time, but relatively high cost.
