The brake drum is generally made of a special type of cast iron that is heatconductive and wearresistant It rotates with the wheel and axle When a driver applies the brakes the lining pushes radially against the inner surface of the drum and the ensuing friction slows or stops rotation of the wheel and axle and thus the vehicle
WhatsApp
A large rotating drum is used to tumble materials in the presence of a process gas or chilled air stream Flights or material lifters pick up the material and drop it through the drying or cooling medium to maximize heat transfer between the process air and the material
WhatsApp
rotating drum no more moving components There is no need for filtration of the compressed air before the dryer and due to the fact that the active material is bounded to the drum there is no need for outlet filtration Rotary drum dryers do not need a separate cooling cycle All these points result in a very low pressure drop over
