Terex says that the TG series complements the Cedarapids MVPX Series (screw-type cone) and the Cedarapids TC Series (floating bowl cone), explained Wayne VanAntwerpen, crusher technology product manager. The new range of TG Spider Bearing cones is being offered in both the large feed secondary and the all-rounder tertiary configuration.
“With the inclusion of bronze bushing technology, we can now open the door to the versatility that bronze bushings bring to the table. For example, the ability to quickly and easily alter the eccentric throw of the cone, on site, simply by rotating the eccentric bushing. No expensive conversions and costly parts,” said VanAntwerpen.
The new Spider Bearing range will consist of four models focused on the aggregate and recycle industries: the TG120 (120hp/89kW), TG220 (220hp/164kW), TG (320/238kW) and TG (420/313kW) respectively. Each model comes in two versions, the TG (tertiary) and TGS (secondary).
The TG style can be run in a secondary, tertiary and a quaternary position. The TGS models, which can take around 75% larger feed, are perfect for a secondary position or even a primary position in a controlled feed sand and gravel application, he noted. There will also be two larger models available for large capacity mining and quarrying applications, namely the TG (820/611kW) and the TG1020 (760kW).
The new TG Series Spider Bearing cones provide nominal maximum feed sizes and applied power similar to current Terex cone offerings, but the numerous eccentric throw options and liner configurations allow for increased application versatility. The TGS Series models use the same base mount as its tertiary version counterparts and operate in the same kilowatt range.
They have fewer linear configurations and options of eccentric throw compared to the TG Series, but these models offer a great advantage over the other styles of crushers. For example, a 149kW (200hp) secondary version Spider Bearing cone can have a similar output to that of other styles of 223-298kW (300-400hp) cones and a maximum feed size similar to that of other styles of 298-373kW (400-500hp) cones.
