CONSTRUCTORS DESCRIPTION :, Spiral elevators, The spiral elevator is
the perfect solution for moving a product upwards while simultaneously
treating it thermally in very small spaces., The conveyor surface is a
rising helicoidal trough, or rather a spiral with a constant pitch.
The width of the trough is determined by the difference between the
helicoid’s external and internal diameter. The product moves upwards
on the conveyor by means of an oscillating thrust movement with
controlled frequency and amplitude, and the direction is inclined in
order to throw the product upwards., The advantages of this solution
are:, -, very small layout space;, - thermal treatments while the
product is on the conveyor (heating, cooling, drying, curing, etc.);,
- speed on the conveyor path can be optimised to guarantee the desired
residence time by changing the oscillating mode of the machine;, -
practically no maintenance;, - the possibility of completely isolating
the product from the surrounding environment (noise, pollution, energy
recovery, etc.) with a dedicated containment structure., The
applications are countless, for example:, - cooling plastic granules
after extrusion and screening;, - treating rubber after
polymerisation;, - cooling scrap metal (swarf, shavings, …) after
oven treatment to eliminate oily residue;, - thermal treatment of food
products., - [Check Constructors
