PURPOSE: A granulator for wood is provided to maximize crushing efficient while finely crushing waste woods into a sawdust form. CONSTITUTION: A granulator for wood comprises a hopper, a crushing rotor(10), a push rod, a cylinder, a screen and a saw blade rotor. The hopper provides woods which will be smashed. The crushing rotor is located at the lower side of the hopper. The crushing rotor smashes the provided wood at the low speed rotation. In the crushing rotor, grooves are formed in the rotor. In the crushing rotor, a byte is spirally combined between the grooves. The push rod pushes the wood provided from the hopper towards the crushing rotor. The cylinder is combined with the push rod. The screen is installed at the lower part of the crushing rotor. The saw blade rotor is installed at the lower part of the screen. The saw blade rotor is rotated at high speed in order to smash first and second crushed material passed through the screen.
