Spiral pipe (roller conveyor) conveyor

- Oct 19, 2017 -

The spiral pipe conveyor is welded with a continuous helical blade in the cylindrical casing, and the casing rotates with the helical blades. The added material rotates and is promoted as a random shell with the action of centrifugal force and friction. In the material under the action of gravity and along the spiral surface, so that the material with the spiral pipe rotation so as to achieve the material moving forward, as does not rotate the screw along the rotating nut as the translation movement, to achieve the purpose of conveying materials.

The machine consumes less energy, low maintenance costs; At the end of the feed, can adapt to uneven feed requirements, can be completed at the same time, the mixing of the conveyor mix, such as a variety of process requirements, the material will not enter too much when the card resistance phenomenon; Convenient for loading and unloading material, can transport the temperature of the material. It is suitable for conveying high temperature materials horizontally, and has good adaptability to high temperature, uneven feeding, crushing requirements, anti-pollution materials and the process of requiring multiple points and discharging. The practice has proved that it has good effect in conveying cement clinker, dry limestone, phosphate ore, ilmenite powder, coal and slag.

The material of the inlet inlet of the end is not more than 1/4 of the screw diameter, and the grain size of the material which is fed from the middle feed mouth shall not be greater than 30 mm. In order to ensure that the cylinder does not produce deformation, the feeding temperature must be controlled under 300 ℃. The abrasion of the blade and the material trough is very serious when the machine is conveying a large material. This design of the screw conveyor mainly used with the transmission of silica micro-powder is very large, so it is not suitable to use spiral pipe conveyor.
