Wood Chipper & Grinder

Wood chippers are equipment commonly used to reduce tree trunks and limbs to further smaller pieces like sawdust and wood chips. These are portable equipments and are towed with a van or truck. The chipper gets power from in built engine that ranges in horsepower from 3 to 1000 or 2.2 kW to 750 kW. You will also find models of chippers that are truck mounted and run on power generated using separate engine.

These wood chippers normally consist of bin for collecting the wood chips, a hopper and the chipping mechanism. The limb or trunk of a tree is put inside the hopper, which then moves into the chipper mechanism. Final wood chips get off from a chute & it is also possible to collect them onto a container or for paper making purpose fed into digester.

Most of the chipping work relies on chippers flywheels, with some also having drums. On the surface of flywheel the chipping blades are generally mounted & flywheel is moved using internal engine or any type of electric motor. Many of the larger sized wood chippers have grooved rollers placed right at the opening of feed funnel. After the roller grips a tree branch, it sends it across towards chipping blades at gradual speed.

Types of wood chippers

  1. High torque roller
  2. Disk
  3. Drum
  4. Others

High Torque Rollers

Chippers that have high torque and rollers for low speed of grinding are grown in stature overtime. The features of these chippers are that they are self feeding, quiet and run on electric motors.

Disk

A comparatively new design has steel disk having knives that are mounted on them as primary chipping mechanism. The good thing about these is that they produce chips of uniform size and shape. They have diameter capacity ranging between six and eighteen inches.

Drums

These have motor powered steel drums that are mounted exactly parallel to hopper. This drum also has the function to work as feed mechanism to draw the wood while chipping it. Nowadays these heavy construction equipments have hydraulic feed wheels which are reversible as are also digitally controlled. These modern equipments come with material capacity ranging between 6 & 20 inches.

Others

There are many larger machines that are capable of handling diameters 2 to 6 feets and employ disks, drums or any combination consisting both. Even larger ones called tub grinders can manage 8 feet or greater material diameters.
