Cost of rotary drier

The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving. The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights

    The illustration compares the lifecycle cost of heatless, blower purge and rotary drum dryers. The heatless desiccant dryer is the most expensive to operate as 15-20% of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls

    Feb 19, 2019 For instance, if your existing rotary dryer drum is showing signs of stress such as cracking, stiffening rings can extend its life until you are ready to invest in a new system. While predicting maintenance costs may be difficult, the best way to gauge a system’s quality is to talk to companies currently operating that manufacturer’s equipment

    The temperature of the air leaving the drier should be selected on the basis of an economic balance between drier cost and fuel cost. It has been that rotary driers are most economically operated when the total number of transfer units (NTU) range from 1.5 to 2.0. Assuming NTU = 1.5. NTU= ln [ [t g1-t w] / [t g2- t w] ] 1.5 = ln [{150- 80}/ { t

    Rotary drum dryers can be designed to withstand extremely high temperatures and/or corrosive materials. A basic carbon steel drum is designed to withstand inlet temperatures from 1,000 F – 1,100 F. Of course rotary drum dryers can be designed to handle different inlet temperatures. Stainless steel can be used in place of carbon steel if the

    Rotary dryers are mainly used in the chemical and mineral industry. In the area of food, their most common applications are for dehydrating waste materials (citrus peels, vegetable trimmings) and animal feedstuffs (alfalfa). Rotary dryers consist of a metal cylinder with internal flights or louvers (Fig. 22.21 ). The cylinder is slightly inclined
