Spiral (roller conveyor) Conveyor

steel cement silo is welded in the cylindrical enclosure has a continuous helical blade, the chassis is rotated together with the helical blade. Added material due to centrifugal force and the friction force and is rotated together with the random shell increased, the force of gravity of the material under the surface and down along the spiral, spiral rotating together with the material in order to achieve the forward movement of the material, as does not rotate along the rotation of the screw nut for translational motion as to achieve the purpose of transportation of materials.
The machine low energy consumption, low maintenance costs; at the end of the feed, they can adapt to uneven feeding requirements, can be transported simultaneously mixing a variety of process requirements, the material does not produce too much into jamming; facilitate multi- point of loading and unloading, can transport high temperature materials. Suitable for horizontal conveying high temperature materials; cement mixing machine, feeding is uneven, there are anti-crushing requirements, pollution prevention requirements of the material and the need to add multi-point discharge process has better adaptability. Practice has proved that, in the transportation of cement clinker, dry limestone, phosphate rock, ilmenite powder, when coal and slag and other materials to good effect.The end portion of the material added to the feed inlet, a particle size of not more than 1/4 the screw diameter; from the middle of the inlet feed material, the particle size must not exceed 30 mm. To ensure that the cylinder does not produce distortion, feed temperature must be controlled below 300 ℃. Aircraft transporting abrasive materials when large leaves and chute wear is extremely serious. The screw conveyor is designed mainly used with its abrasive silica transport so not suitable for a large spiral conveyor.
