Troughing idlers are fixed frame type idlers. This Troughing idler or idler set support the belt run on the carrying side. In this the center roller is horizontal and two side rollers with an inclination of 20,25,30,35,40 ,45 degrees & customized angle as per requirement. This angles of side roller are known as troughing angles.
The use of troughing idler reduces pinching & belt fold up. The maintenance is easy, all three rollers are identical & interchangeable reducing the maintenance stock.
Impact Idlers Frame (Trough impact idler)
The impact idlers are used in the material feeding zone to support the conveyor belt on the running side. This impact idlers absorbs the impact by the material falling on the belt, protecting it from the wear & tear. The impact rollers are forced fitted with rubber ring made from natural / Synthetic / Neoprene material. The fixing arrangement and dimension of rings are suitably design for easy replacement and interchange ability which protect the belt by absorbing impact at loading point. 20, 35 and 45 degree Troughing Angle.
V-trough Carrying Idler Frame
The V-trough idler is used as an alternative to three roll trough idler as same contain two rolls instead of three. This arrangement is generally used for less belt width & material of limited lump size.V-type Return Idler
The v-type return idler is used to support the return belt run. This provide better alignment for the belt, compared with single roll return idler.
Flat Return Idler Frame
Flat return idlers have a single horizontally aligned roller to support the belt on the return run.
Garland Idlers Frame
Garland idlers are 2, 3 or 5 roller, which are linked in series and suspended at the ends from the stringer.
These arrangement of idlers looks like garland or catenary & thus called so. The idlers have flexibly connected rolls as well as it is also flexibly connected to the stringer. If a single roller is found defective then it can be replaced easily without stopping the whole conveyor system. These are lighter in weight compared to fixed frame idlers. Suitable for long conveyor systems.
