YT-VB Valley Beater

The machine uses the mechanical force generated by the flying knife roller and the bottom knife to cut, crush, knead, split, swell, and refine the fiber slurry, and at the same time produce displacement and deformation of the cell wall and the primary wall of the fiber. And the rupture of the outer layer of this wall. According to the pressure and beating time of the bottom knife, the changes of pulps with different beating degrees can be obtained. The Vally beater is widely used in the beating test of various plant fibers, synthetic fibers, carbon fibers and glass fibers. It is a paper production test, Papermaking experiment equipment indispensable for quality control, process formulation, teaching and research experiments.

● Laboratory roll is a stainless steel with a middle wall , which circulates around the mass driven movement rotating drum roll.

●  Drum roll is a cylinder with a diameter of 168mm, attached horizontally to the bearing side and the medial wall of the tub. On the circumference of the knife roll 32 is located a stainless steel.

●  Planck roll is a structure of 7 identical knives in a chevron shape , mounted in the lead block and fixed filled with white oak .

●  Such a design prevents touch knives. Planck has a rubber diaphragm, allowing it to freely move up and down with a lever to which it is attached . Load on the lever depends on the type of the pulp and 2 kg for the mass of hardwood and 5.5 kg for the mass of conifers.

●  Nominal capacity of 23 liters roll that the standard 360g fiber rigging creates a working concentration equal to 1.57 %.
