Circular Saw Firewood Processors

High volume firewood production involves loading multiple logs into a machine which buck the logs into predetermined block lengths and then split the blocks into firewood. With these machines the operator does not handle the wood over the entire process.

Multiple logs are loaded on to the infeed deck using a fork lift, log loader or other lifting device. The operator can move the deck chains forward and feed a log into the infeed conveyor. The infeed conveyor is then advanced till the log reaches an adjustable mechanical stop or visual indicator. This allows the operator to ensure that all pieces of firewood are consistent lengths. Before the cutting operation the operator lowers an arm or hold down spiked roll to hold the log in place. The operator activates the circular cutoff saw and cuts through the log either by mechanical or operator movement. The cut block falls into a trough below where the ram is activated and the block is forced into a wedge (2, 4, 6, or more ways) and split into firewood. The split firewood either falls on the ground to be stacked or falls into a conveyor to be piled in a truck, bin or the ground. To repeat the cycle the operator raises the hold down arm (hold down rolls are not raised) and advances the infeed conveyor till the log reaches the log stop or indicator.

Firewood production speed is dependent on the ability to feed the processor logs, log size, operator skill and ability to remove the firewood quickly. Production speeds depending on equipment range from 1 to 6 full cords per hour. Log diameters range from 4 inches to 30 inches. Additional options include operator cabs, integral or separate outfeed conveyor belts, auto wedge adjustment (height and number of wedges), auto cycling and self loading infeed decks.

Circular saw firewood processors are typically hydraulic and powered by medium to large gas/diesel engines or by the Power Take Off (PTO) from a tractor. They come in horizontal configurations, are portable and can easily be towed behind a medium/heavy duty pickup truck. Electric drive / stationary units are also available.
