In 2007 Obajana Cement constructed a new cement plant in Kogi state, Nigeria. Obajana Cement is part of the impressive privately owned Dangote Group and the Obajana Cement Plant is now the largest in Sub-Saharan Africa. The project was managed by ACC, India and FL Smidth were lead equipment suppliers. This new site contained eight large cement storage silos (61m in height and 18m in diameter).
Shortly after commissioning Obajana Cement contacted Primasonics International to ask their advice in solving side wall material build up and blocking within these large silos. First of all the silos had to be cleaned in an efficient and safe manner before Primasonics Acoustic Cleaners could be installed. The initial decision the company had to make was whether to employ an international silo cleaning company or purchase their own safe, rapid silo cleaning equipment. With a total of eight massive silos to clean out, it became obvious that by far the most economical solution was to purchase their own silo cleaning equipment and they chose the Primasonics Prima Whip. At the same time Primasonics technical staff had concluded that each massive silo required the installation of twin Acoustic Cleaners Model PAS-60, the most powerful audiosonic acoustic cleaner available.
By late 2007, Obajana Cement had taken delivery of the largest version of the Prima Whip plus a total of eight Primasonics Acoustic Cleaners Model PAS-60 for four of their storage silos.
The results were so successful that the following year, the Obajana Cement placed another order with Primasonics International for the supply of a further eight Model PAS-60 Acoustic Cleaners for their remaining four storage silos.
It seems good news travels fast, Primasonics were contacted by Lafarge Cement WAPCO Nigeria Ltd,Sagamu Plant, who were interested in the Primasonics Prima Whip for cleaning their numerous cement silos. After discussions with Primasonics technical team Lafarge Cement made the decision to purchase the Primasonics Prima Whip. After 12 months of using Primasonics equipment here is what the Sagamu Plant Maintenance Manager has to say:-
We have used the Primasonics Prima Whip for several months now on a cement silo cleaning program where we consider safety our first priority. We purchased the Primasonics Prima Whip system so we can remove the build -up in the silos from above in a safe and efficient manner, thus eliminating the danger of manually going inside to work.
We are now successfully completing Prima Whip cleaning of our second silo of the four we have in use and in total we have been able to remove approx 1,500 tonnes of caked up cement.
The process we use is to open up from the centre and work around to release the cement from the side walls and down to the outlet. We then work on all the build-ups on the walls of the silo to make sure when we enter from the side hatches at the base of the silo so as to remove all the free cement lying in the bottom no material is left on the walls which could fall and engulf or injure our workers. This can now be safely and quickly done without the risk of injury to our workers. When this is complete we can then overhaul the extraction systems and air slides and put the silo back into full operation.
The Prima Whip system has worked very well and has been a big success for us in this project. Thank you Primasonics for all your help and for supplying us with our Prima Whip.
Primasonics are now in discussions with personnel at the Sagamu Plant about installing the Primasonics PAS 60 model Acoustic Cleaner on their clean silos to prevent the build up from re-occurring.
