For a single drum, the thickness of the film can be controlled by ___________ and in case of a double drum setup the thickness of product here can be controlled by ______________

For a single drum, the thickness of the film can be controlled by ___________ and in case of a double drum setup the thickness of product here can be controlled by ______________ Correct Answer An adjustable scraping blade, the gap between the drums

The drum dryer can be represented as – A drum dryer as given in the diagram above, a mixture of feed having quality solid suspension which is to be dried, is fed to it from the top the rotating drums which there after forms a thin layer on the surface of the rotating drum, which then falls as a powdered product at the bottom. If we use a double drum, the product layer thickness can be controlled by the gap between the two drums which can be readily adjusted.

A haulage rope winds on a drum of radius 500 mm, the free end being attached to a truck. The truck has a mass of 500 kg and is initially at rest. The drum is equivalent to a mass of 1250 kg with radius of gyration 450 mm. The rim speed of the drum is 0.75 m/s before the rope tightens. By considering the change in linear momentum of the truck and in the angular momentum of the drum, find the speed of the truck when the motion becomes steady.
