Refiner

Deflaker for Fiber Cement Board Production

DESCRIPTION

The multifunctional and efficient deflaker/ refining and desanding machine is mainly used in the papermaking industry (bleaching) for continuous refining of purified slurry or for homogenizing and refining waste paper regenerated slurry after deflaking. It is also used in the fiber cement board production industry.

After treatment, the tensile strength, bursting strength, bonding strength and beating degree of the fiber can be improved. The pulp processed by this machine can obtain better tensile strength, folding resistance, and better combination of stiffness and air permeability. This machine can be used with double disc mills in series for refining, with conical mills for refining in series, or as a stand-alone machine.

The multi-functional and efficient deflaker/ refining and desanding machine mainly consists of a frusto-conical rotor of the blade, a frusto-conical shell and a gap adjustment mechanism. The slurry is fed into the small end of the shell and discharged from the big end, so that the rotor can The shell is realized by axial relative movement. It adopts elastic cylindrical pin coupling and has low noise. Both ends of the rotor are supported by double-row radial spherical roller bearings, which improves the rigidity and strength of the shaft, greatly reduces noise, and the machine speed is stable without obvious vibration. The rotor, stator and toothed disc are made of alloy cast iron toothed disc, which greatly improves the service life.

The primary function of the fiber cement board deflaker is to separate and deflake the cellulose fibers, ensuring that they are evenly distributed and well-dispersed within the cement matrix. This process is essential for enhancing the bonding properties of the fiber cement board, as well as improving its structural integrity and overall performance. By effectively deflaking the fibers, the resulting boards exhibit enhanced strength, flexibility, and resistance to environmental factors such as moisture and impact.

Advantage

This deflaker has the advantages of novel design, high production efficiency, long refining area, good refining quality, accurate control of the advance and retraction gap, low power consumption, low noise, easy operation and easy maintenance.
