BPJ Barking Machine

• Introduction

BPJ wood barker is a kind of neoteric wood log debarking machine, featuring 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 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.

• 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.

• Attention:

The barking machine can be used with Wood Briquetting Plant or alternatively, it can be put into used individually. Some clients may use wood logs to produce briquettes and hope to have the barking machine integrated with briquetting plant. Therefore, you can take into account BPJ Wood Barking Machine. It can be used with Briquette machine and other machines.

Note: Barking rate may be different due to the drying degree of wood logs. Generally, dry wood logs with the barking rate of about 90% and fresh wood logs with about 95%.
