AAV STARTER ELBOWS VSD IN HAMMER MILL CONTROL CONTEST

摘要

At a site adjacent to Cottam Power Station in Nottinghamshire, EdF pulverises olive cake, which is made from the husk residue that remains after olives have been processed to extract their oil. The ompany then mixes the pulverised cake with coke to form an environmentally friendly biofuel that is burned in the power station. The pulverising process is carried out using a hammer mill comprising a cylindrical 'squirrel cage' with six bars. Hammers are attached to these bars and, as the cylinder rotates they flail outwards, reducing the olive cake to a consistent size suitable for mixing with the coke. To ensure that the hammers wear evenly, the direction of rotation of the mill reverses each time it is started.
