Our rotary dryers are built to the highest quality standards, with longevity in mind. The best part about buying a FEECO rotary dryer, is that you get the security of knowing
2019-1-16 Take the maximum superficial air velocity to be 1.2 m/s (this is 20% less than the maximum allowable velocity since part of the dryer is filled with the moving solid, and the entire cross-section is not available for gas flow). If d is the diameter, (πd2/4) x (1.2) = 3.686 = d = 1.98. Select a 2 m diameter shell.

Proper flight design is a key component in optimizing the efficiency of a rotary dryer, with geometry, pattern, and more influencing overall dryer performance. With decades of drying experience, our team of engineers has a vast knowledge base of materials
2021-7-13 Rotary drum dryer by Palet Machinery is specially designed for drying the sawdust, wood shavings, wood chips, woodblocks, rice hull, chicken manure, grass, bean dredges, cassava residue, cassava residue, sludge,etc. The structure of the rotary dryer adopts the means of cylinder marginal transmission, flange connection, direct heat transfer.
2018-12-6 The rotary dryer cylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into the rotary dryer cilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in the rotary dryer cylinder body, the lifting plates inside the rotary dryer cilinder makes the
