Rotary Dryer
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.
