Improvement in Maintenance of Scroll of Decanter Centrifuge Machine to Improve the Average Life

Lots of work has been done on the design, maintenance and other problems encountered during the operation of the Decanter Centrifuge. It is a Mechanical rotating equipment used for separating dispersed solids from the dispersed solutions. The machine is generally used in Cement Company, sugar mills, distilleries, coal mines, wine manufacturing, breweries etc. The study is based on three Humboltz, Germany made decanters used in a 120 KL grain based distillery plant located near Ambala district (Oasis Commercials Pvt. Ltd.). There were numbers of efforts made to increase the life of the scroll and the other operating parts starting from the main line feed pipe. Then there was some modification made in the design of the scroll and the data was observed to before and after to notice the changes (if any). Then there was a the decision making for the usage of the type of the hard facing material applied on the screw conveyor (scroll) and it was done by comparing the different jobs with the different hard facing materials both in lab and in the actual working condition. The decision was then took by comparing the performance of each job and keeping economical aspect into consideration. The study and observation helped a lot to improve the working condition and the life of the scroll to a considerable range.
