DESCRIPTION OF THE PROBLEM
Reavell hammers made in France in the years 1982-1985 and used for shaking off the fertilizers granulated on the walls of the dryer during the drying process are installed in the rotating dryer in the Fertilizers Plant NPK-2. The hammers' tubs have rubber covers which are completely degraded after 10-14 days of their utilization. It was necessary to reconstruct the elastic cover and achieve an increase in its durability. It was decided to regenerate it with elastomers of CHESTER MOLECULAR.

DESCRIPTION OF THE REPAIR
There were made new steel bases to place the elastomer covers and steel rings to pour out the covers. The surfaces of the base were degreased with Chester Cleaner and covered with EL 20 activator, while the surfaces forming the rings were covered with the Chester Release Agent separator. Then there was poured Chester Elastomer 90F in one base and Chester Elastomer 75F in the other one.

ACHIEVED EFFECTS
Possibility of the repair of the tups in the plant, the repair duration – ca. 30 minutes. Increase in the durability of the cover made of elastomer (it has been functioning for 70 days already). The reduction in costs of this repair.
