Rotary dryer is used to burn the hard magnetic ferrite powder; it can also be used in cement, metallurgy, chemical industry. The equipment is composed of the main kiln and its supporting transmission, cooling pipe, fuel system, electrical control, the second wind devices, exhaust dust removal device and preheating kiln body. It has the over temperature alarm, overload alarm, work automatic temperature control, and kiln oxygen adjustable functions.
Rotary Dryer Working principle:
Wet material is input from one end of the dryer, under the copy board flip of the inner cylinder cloth, material is uniformly distributed and dispersed in the dryer, and fully contacts with the hot air stream (countercurrent) to speed up the drying heat transfer, and mass transfer driving force. During the drying process, the material in the copy board and the hot gas stream with the inclination of the role, it can regulate movement to another section star-like discharge valve to discharge the finished products.
Rotary Dryer Applications:
1. It is applied to the dry chemical, mining, metallurgy and other industries’ large particles than significant materials.
Such as: ore, blast furnace slag, coal, metal powder, phosphate, ammonium sulfate.
2. To the powder have the special requirements like: Foaming agent, lees residue, precipitated calcium carbonate, activated clay, magnetic powder, graphite, dregs.
Feature:
Require the low-temperature drying, and requires large quantities of continuous dry material.
Rotary dryer has high degree of mechanization, large production capacity.
Fluid through the cylinder the resistance is small, consumption function is low.
The strong adaptability to the material properties.
Stable operation, low operating costs and good dried product uniformity.
