Charcoal Powder Rotary Dryer Machine with wood sawdust crusher
wood sawdust crusher machine
How does the crusher machine make woog log and tree branch to
First ,The wood log diameter shall smaller than the mouth of
sawdust making machine.
Second,We put the wood log directly in to mouth of wood sawdust
machine ,with rotation blades and hammer shaft ,the log will
crushed gradually and draged into the crusher blades .In the
crushed chamber ,the wood log chipped by the blades first ,then
then the chipped wood chips hammed by the rotation hammers ,it
become smaller and smaller until it can come out from the bottom
screen get the fine sawdust.
Wood chipping first ,making sawdust second ,all of them in one
crusher chamber ,two connect process.
Specification of crusher machine for making sawdust
Introduction of coal powder rotary dryers
coal powder rotary dryers is suitable for drying materials from
moisture 20%-60% to 6%-8%. It is consist of hot air stove,inlet,
steel buffer cylinders pipe, exhaust fan,air lock and cyclone
1. It is widely used for drying the powdery,laminar materials like
wood sawdust, crop straw,grain stalks etc.
2. It is specially suitable for drying the starch,albumen powder
from food such as corn,potato etc.
3. It is also for drying the granular and spiny materials in
chemical products, medicine and biomass industry.
Working theory of coal powder rotary dryers
Wet materials are input into the hopper. It uses the varying
diameters of branch segments of pulse tube and continual change of
air flow speed to constantly thrash the material for drying.The
fuel boiler generates hot air which mixes with wet materials and
then is sucked into the pipes by the exhaust blower (fan) quickly.
And then hot air is flowing and going though the curving pipes and
buffer (drying chamber) of dryer, thus wet materials is finished to
dry, and the dried materials are discharged from the outlet with
Features of coal powder rotary dryers
1. As the raw material particles are suspended in the hot air
stream, the heat transfer between the hot air and particle is
rapid. That ensures efficient moisture removal, even with a short
transfer time of 3-5 seconds
2. Once the moisture hot air and particles reach the cyclone
separator, the particles leave the through the base and moist hot
air leaves through the top of the cyclone.The buffer cylinders are
to increase particle resonance time in the hot air stream.
3. The dryer usually uses coal, firewood and gas as heating
source.Combustible gas as the heating resource can save labor 75%.
4. it not only reduces the labor intensity but also can reuse the
