Rossi have developed innovative geared products for synchronising drives. One such application is used in mobile and fixed asphalt mixing plant. The synchronising drives are used in hot asphalt and bitumen batch mixing process. The batch mixing machine has two contra-rotating horizontally paddles, driven by a pair of Synchronised identical ratio Rossi bevel helical geared motors. In this application it is vital to have both paddles synchronised to prevent one paddle driving into the other or for one paddle to take more load than the other, to ensure a proper mix of product and prevent failure of the expensive mixing paddles.
