R80 roller chipper (4 knives) Remet CNC Technology

Tractor chipper - how does it work?

These are devices that, as the name suggests, are designed to be used in conjunction with agricultural tractors . A tractor chipper works by connecting to the PTO shaft, which is why individual chippers require connection to a tractor with the appropriate engine power. Wood shredding machines are commonly used in forestry and agriculture. Their use allows for quick, precise and safe processing of even a significant number of trunks and branches.

Basic types of chippers: disc and roller. What are the differences?

In disc chippers, the element that shreds wood is a metal disc/disc with mounted blades (knives). This solution was patented in 1922 by German inventor Heinrich Wigger. The rotating disc/disc is set perpendicularly to the wood fed into the machine (manually or by means of a conveyor belt). The rotating disc with knives shreds it into chips (shavings), which are then thrown out of the device through the discharge chute. By choosing a disc chipper , we obtain fine material of uniform shape and size, which can then be used for mulching, for fuel, for the production of chipboard.

Roller chippers are machines designed to quickly process branches or tree trunks into short pieces. These devices are great for forests, parks, orchards or farms. Roller chippers have a completely different shredding mechanism. It is a rotating cylinder with sharp protrusions (knives). The material we get is wood cut into pieces about 10-16 cm long.

The R-80 roller chipper is designed for cutting branches with a diameter of up to 7 cm (fresh soft wood).

The construction of the chipper is welded, fully disassemblable, ensuring the appropriate rigidity and durability of the machine. The cutting mechanism has been precisely made, ensuring the appropriate quality, accuracy and concentricity. This translates into a long service life of the components and the entire device.

The chipper mechanism is equipped with a clamping and expanding sleeve that is used to position the cutting knives, it also serves as an overload protection. The chipper can be additionally equipped with a flywheel/belt and a foldable belt conveyor. The belt allows for discharge along or to the side of the device.
