Wood Barking Machine
In a pellet plant, BPJ wood barking machine as a kind of neoteric wood log debarking equipment features highly debarking efficiency. The type of wood barking machine can be separated into two models due to different wood logs and distinct wood log diameters, namely BPJ single roller barking machine and BPJ twin roller barking machine.
The barking machine consists mainly of main shafts, inlet, bark outlet and wood outlet and driving system. The newly designed separated outlets for wood logs and bark can ensure a constantly stable performance so that a continuous peeling can be realized. The unique strength formed by rotors with staggered aligned teeth (or called cusps) will rotate wood logs in a reciprocating circle in the chamber, furthermore, wood logs under the force will gyrate itself with irregular throbs so that between logs and those cusps, logs each other as well as logs and peeling groove, forces of rubbing, bumping and squeezing will mingle together to peel off logs. The twin-roller debarker is capable of peeling wood logs of 70-100 tons daily. If the material you offer for pelletizing is oversized like logs or timber or lumber, the first step may be peeling them off.
Characters:
1. The open type groove can have successive production realized with one end as inlet and the other outlet, which is quite different from the drum type barking machine working in a segmented way.
2. Because of the blended forces of bumping, rotating and friction, frozen wood, dried wood logs and some hard-to-peel wood material can be peeled off with a higher performance by the roller barking machine.
3. The wood barking machine adapts itself to many kinds of trees with distinguished diameter, length and forms. Thanks to the gyrating and irregular bouncing forces, even some bent logs and concaved parts can contact with debarking teeth, which features a higher barking rate.
4. The barking machine, due to the stably behemoth body, is characteristic of low energy consumption, low rate of default and low maintenance costs. Besides, vibrating degree and noise ratio are much lower than the drum type wood barking machine. The BPJ wood barker can be equipped with conveying system in favor of labor reduction and to enhance production output.
Application scope of the twin-roller debarker
It is widely used to debark coniferous wood, broad-leaved wood, partially for frozen wood and dried wood. The twin-roller debarking machine can serve fields of medium-density fibrous board, paper mills, veneer rotary-cutting, wood chipping, paper pulp, wood storage and forestry farm. In particular, the peeling rate of wood species like eucalyptus and poplar can reach at least 95%.
Therefore, before take wood logs, timbers or lumbers as material for a pellet plant, you may take the debarker into consideration.
