WOOD CRUSHING MACHINE (FLAKER)

ENERGY INDUSTRY

The main purpose of the wood crushing machine is crushing of the non-conforming wood waste and logging of the type: slab wood, edging, dead wood, branches and treetops. The flakers also worked well when cleaning the forest plantations, sanitary zones of big cities, clearing of power lines, cleaning the roadsides in the technological and fuel wood chips (sawdust). The wood chips received as a result of the wood processing are used for the manufacture of MDF (Medium Density Fireboards); production of briquettes and pellets; decoration of the parkland; insulation of the floors in farming enterprises; making compost, as well as biological fuel for the thermal power plants, boilers and gas generators.

The basis of the wood crushing machine is a single steel disc of 800 mm in diameter. There are installed two cutter knives on the chipper disc and one counter knife in the machine body. The raw material is fed into the hopper by the worker by hand and is dropped to the working zone by using the hydraulic supply system.

Among technical advantages of the wood crushing machines can be noted:

  • Great performance – up to 10.0 m2/hour (6 t/h), depending on the type of crushed material;
  • Large amounts of crushed wood waste of 160 mm in diameter, 240 mm in width, and of any length;
  • Presence of the material infeed mechanism in the machine working zone;
  • Ability of hydraulic regulation of the wood chip faction sizes on the output from 10 to 30 mm;
  • Adjustment of the direction and height of the wood chip ejection from the wood chip disposer.
STATIONARY

The stationary wood crushing machine of disk type is equipped with a drive from the electric motor, with the inclined infeed hopper, hydraulic supply of the raw materials and wood chip ejection. It is installed stationary on a flat surface and does not require anchoring. The machine drive is made due to the electric motor through a belt transmission.
