Gears help automate spinner block
Each SB4F main spinner block drive features a Flender FZG gear unit size B2DV16 with its own oil supply system, Siemens DC main drive motor and Siemens control equipment.
Two have an integral inspection drive - a separate slow speed drive to help regular maintenance via visual checks of the belts.
Four of the units are Flender size 2s, two are size 3s, two are size 4s, two are size 5s and two are size 13s (the largest size on this contract).
Most are fitted with Flender Fludex input couplings and all are designed to cope with extremely low ambient temperatures at the port (-37C) through the fitting of integral heaters.
The conveyors are all housed in gantries and will transport granular fertiliser prills - a byproduct of the petrochemical industry - that have come in by rail wagon from Russia to temporary storage in four 40m diameter dome silos before being transported onto ships via a series of 12 conveyors.
A key requirement of the contract was self-cleaning material handling equipment, as well as the capability of handling hygroscopic and often highly corrosive fertilisers.
The coastal environment was also a consideration, so many of the fabrications have been designed in stainless steel or mild steel coated with high specification paint systems.
AS-C's Project Manager Graham Davies described the complexities of the job: "As the material being handled is fertiliser additional safety requirements were necessary; it was therefore essential that non-explosive drive equipment be used.
We are very pleased with the units and parts of the project are already up and running".
Final completion of the project is expected in summer 2002.
