U-shaped groove spiral conveyorIt is an ideal conveying equipment for bulk powdered materials, providing enclosed transportation to prevent the spillage of powdered materials. The U-shaped groove spiral conveyor can add materials from one or more entrances, making it very convenient to use. The U-shaped groove spiral conveyor can transport materials horizontally or obliquely. When space allows, it is a very economical lifting and conveying equipment. However, as the inclination angle increases, the conveying capacity will decrease.

Six specifications of U-shaped groove spiral conveyor: Spiral diameter: LX220、LX250、LX300、LX350、LX400。

Six standard revolutions per minute: 35, 45, 75, 95, 120, 140

Spiral machine length: from 0.5 meters to 15 meters, the conveying length can be freely selected

　　Characteristics of U-shaped screw conveyor:

1. U-shaped groove spiral conveyor has high power, low energy consumption, small volume, and does not occupy land

2. Strong conveying capacity, smooth conveying, uniform conveying of materials, and less likely to get stuck

3. Convenient maintenance, easy upkeep, and low failure rate

4. Belonging to environmental protection equipment, it does not cause dust during material transportation, does not pollute the surrounding environment, and has good sealing performance

　Working principle of screw conveyor:

When the spiral shaft rotates, due to the gravity of the material and the frictional force generated with the groove wall, the material can only move forward along the groove bottom of the conveyor under the push of the blades, as if a nut that cannot rotate moves in translation along a rotating screw. The movement of materials in the middle bearing relies on the thrust of the materials moving forward from behind.
