Customizable single-roller, double-roller, and triple-roller structures to meet the needs of various materials. Working Principle of Wood Debarking Machine: The debarking machine utilizes the force generated by a rotor equipped with debarking teeth to make wood logs undergo continuous cyclical motion within the hopper’s chute plates. At the same time, the logs also rotate around their own axes and perform irregular bouncing movements. As a result, the logs constantly rub against the teeth, collide with each other, and are squeezed between the logs and the chute plates, rapidly separating the bark and achieving the desired debarking effect. Scope of Application: The groove-type wood debarker is suitable for large, medium, and small-scale paper mills and pulp mills, as well as enterprises from various industries involved in wood processing—such as wood chip plants, lumber yards, wood processing factories, forestry enterprises, and man-made board factories (e.g., plywood mills, medium-density fiberboard mills). In recent years, due to China’s vigorous logging activities, nearly ten million acres of poplar plantations have been established in southern forest regions, all of which require extensive use of wood debarking machines. The wood debarker, also known as the groove-type double-roller wood debarker, operates on the principle that the rotor equipped with debarking teeth generates greater force, resulting in higher efficiency, faster speed, and greater output. The wood logs continuously circulate within the hopper’s chute plates, rotating around their own axes and performing irregular bouncing motions. This constant friction, impact, and compression between the logs and the teeth, as well as between logs themselves and the chute plates, quickly separates the bark, achieving an effective debarking result. The double-roller wood debarker adopts a roller-based debarking mechanism, featuring a simple yet robust structure with high rigidity, low failure rate, and long service life. It consists of five main components: the debarking roller, feed inlet, bark outlet, wood outlet, and power transmission unit. Unlike traditional drum-type wood debarkers, which require stopping the machine for both feeding and discharging, this machine separates the bark outlet from the wood outlet, enabling continuous operation. The entire process—from feeding, debarking, wood discharge, refeeding, re-debarking, and re-discharge—is continuous and uninterrupted, allowing for streamlined operations. Depending on different wood species, the debarking effect can be adjusted accordingly; even wood of varying lengths, bends, spirals, and moisture levels can be processed effectively. Features of the Double-Roller Wood Debarker: 1. It features an open hopper design, allowing for continuous, linear operation with material fed in at one end and discharged at the other, overcoming the drawbacks of existing drum-type debarkers that require stopping the machine for feeding and discharging and operate in segmented cycles, thus achieving high work efficiency. 2. Thanks to the impact of the teeth on the wood logs, not only do the logs circulate within the machine casing but also rotate around their own axes, resulting in high debarking efficiency. It delivers excellent results when debarking difficult-to-peel species such as eucalyptus and poplar. 3. Highly adaptable to various types of wood, it can handle logs of different species, diameters, lengths, and shapes. Due to the logs’ back-and-forth movement and irregular bouncing, even concave sections of bent logs can make good contact with the debarking teeth. Therefore, its bark removal rate for bent logs is significantly higher than that of other drum-type debarkers. 4. Low energy consumption, low failure rate, minimal maintenance requirements, and much lower vibration and noise levels compared to drum-type debarkers. The machine can start production immediately after being placed on the ground—even without the need for a foundation installation—making it extremely convenient to use. Application Scope of the Double-Roller Wood Debarker: It is suitable for debarking freshly cut coniferous woods and some broadleaf woods, and can also handle partially frozen or dried wood. Differences Between Single-Roller and Double-Roller Debarking Grooves: 1) The single-roller debarking groove has a side opening, offering high bark removal efficiency but requiring significant manual labor; 2) The double-roller debarking groove can be connected in multiple sections; 3) The single-roller debarking groove is suitable for logs over 20 centimeters in diameter; 4) Depending on the diameter of the roller, the single-roller debarking groove can be classified into different sizes, including 426, 480, 508, 600, and 800 millimeters.
