The principle of spiral conveying is the same as for the horizontal vibrating conveyors, however the product is conveyed in a path that is spirally coiled around a vertical center tube. The spiral elevator is suitable to a wide range of operations. Among these are products with dry, wet, warm, greasy and frozen characteristics. The spiral elevator is also able to convey with simultaneous cooling, heating, drying, spreading or unification system.
The spiral elevator is robust, maintenance-free (no lubrication or regular inspection necessary) and is developed to meet the present environmental requirements, as for example reduction of noise, dust and odors.
Due to the special combination of oscillation and frequency of vibration as well as stroke length, the spiral elevator is extremely gentle in the handling of the products.
