For
carrying materials or packages from one place to another the conveyor
belt system is used. The conveyors are used not only in small and big
industries but are also used in mining and tunneling operations. Spiral
conveyors are those types of conveyors that are very effective in tight
spaces. They are also known as spiral lift, spiral curve, spiral
elevator, or spiral lowerator, case lift and case elevator. Features :
- During tunnel excavation process, materials after being crushed are removed from the boring chamber by a spiral conveyor.
- During tunnel construction, spiral conveyor functions like an Archimedean screw.
- The spoil on a conveyor belt is deposited by the screw and from conveyor it is transported into small work trains.
- While boring in areas with heavy water inflows, the excavated material and a continuously filled spiral conveyor ensure that the pressure in the excavation chamber is maintained.
