Need to know

Paper pulper machine, also called paper pulper, refers to the machinery used for breaking, dispersion in the paper and pulp industry. To be clear, paper pulper machine process board plate, waste paper, broken paper, or other kinds of materials into pulp.

Hydrapulper is a typical paper pulper machine. Hydrapulper also is known as hydro pulper, is commonly used for waste pulp production. According to the structure, hydrapulper can be divided into vertical hydrapulper and horizontal hydrapulper.

Vertical hydrapulper

The main structure includes tank, rotor (impeller), bottom knife ring and motor. Generally, the circumferential speed of the turntable is 1000m/min, and the diameter of the groove body is 1-6m.

Working principle: Start the motor, the impeller starts to rotate, the slurry in the tank is sucked along the center of the axis and thrown out from the circumference at high speed, forming a violent turbulent circulation. Due to the tearing of the impeller blades and the mutual movement of the slurry layers of different speeds, a huge friction is generated, which makes the slurry intensively decompose and separate the fibers in the wet state, and the fiber bundles are rubbing against each other in the gap between the impeller and the sieve plate, increases the effect of fibrosis.

Horizontal hydrapulper

There are two types: Volt hydrapulper and drum type hydrapulper.

The Volt type hydrapulper has a side-mounted rotor and an impurity collector at the bottom of the tank. The other structure is the same as the vertical pulper. This type of pulper can process unsorted waste paper.

The drum type hydrapulper can continuously remove non-fiber impurities that are difficult to disintegrate and has a large production capacity. It uses the partition on the inner wall of the cylinder to continuously lift up the paper material, and drops it to the bottom of the cylinder at a certain height, and uses the tearing and shearing effect to achieve the purpose of dissociating fibers. Major impurities are not damaged by machinery and can be easily removed by impurity removal equipment.
