PL4-A Valley Beater
This machine is widely used as a standard tester per JIS and TAPPI. Unlike the conventional beater, the roll is fixed, and a constant load is applied on the head plate, thereby constantly giving a uniform beating pressure. It is excellent especially in free beating and wet beating. So it is very effective for quality management.
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 %.
This machine satisfies ISO 5264/I, TAPPI-T200 as well as GB7980YI87 laboratory beating Valee the (Valley) beater law (Pulps-laboratory beating-Valley beater method) and so on standard requests. This type may change the heavy thallium pressure, the beating time, and automatic control beating time, thus obtains the different experimental result.
