Lifting (spiral)

Another type of system for moving and transferring materials that is used from one level to another level with a higher height is elevators or spiral or screw conveyors.
This type of conveyor is mostly used in industries where additional operations on the material or product during movement require time, such as drying, processing, heating, cooling, etc. , is used.
For example: – Cooling the grains of plastic material after being electroded
– Applying rubber after polymerization
– Cooling metal parts after heat treatment
– Thermal operations on food
-Remove fat and excess material from the parts and prepare for the next process
The performance of these conveyors is based on the structure of a spiral, usually a snail, which increases with a certain pitch of the spiral and is designed  .in different widths and heights, according to the needs and usage
