What’s the advantage of ‘plug and play’ rotating parts for Symetro gear units? Ash Grove found out to their benefit when a 30-year old Symetro unit suffered damage due to an unforeseen event in the mill system.
At Ash Grove Cement Company the Symetro-driven mill was stopped due to an unforeseen event in the mill system, which had a negative impact on the gear unit. The visual inspection in March 2008 showed the gear unit to be in critical condition: two broken teeth and cracks were found on the low-speed pinions….It can take up to 12 – 13 months to deliver a new set of rotating parts. The FLSmidth MAAG Gear specialist recommended that Ash Grove should purchase a new TSHH Plug and Play in order to secure mill operation. Installation of a new set of rotating parts itself only takes about a fortnight.
