Wet Broke Pulper

Wet Broke Pulper is a specialized equipment designed for the efficient processing of wet broke in the papermaking industry.

The main purpose of a Wet Broke Pulper is to break down and disintegrate wet broke - which refers to paper that has become damaged or defective during the papermaking process, or excess paper that needs to be recycled - into a fibrous suspension. This pulper works by using a mechanical and hydraulic action to achieve this disintegration.

In terms of its construction, the Wet Broke Pulper typically consists of a large tank or container where the wet broke is placed along with water and, sometimes, chemical additives to aid in the pulping process. Inside the tank, a rotor or impeller rotates at high speed, generating strong currents and forces that help in breaking apart the wet broke and separating the fibers from one another and from any impurities or adhesives.

One of the key features of the Wet Broke Pulper is its ability to handle a significant amount of wet broke in a relatively short period of time, which increases the efficiency of the papermaking process and reduces waste. Additionally, it is designed to minimize the damage to the fibers during the pulping process, ensuring that the quality of the resulting pulp is maintained at a high level.

The Wet Broke Pulper is an essential component in a papermaking facility as it helps in recycling and reusing the wet broke, contributing to cost savings and environmental sustainability in the industry.

Used for breaking wet broke on the wire section of paper machine in pulp and paper industry.

1. Using propeller type rotor, high efficiency of breaking wet broke, large matching capacity and low power consumption.
2. Driving mode:belt drive and reducer drive.

The working principle of the Wet Broke Pulper is to put the wet broke and an appropriate amount of water into the tank of the pulper, and generate strong hydraulic shear force and mechanical friction force through the high-speed rotating impeller or turntable.

Under the agitation of the impeller, the water forms a powerful current and vortex, which quickly soaks and involves the wet broke. The wet broke is repeatedly impacted, rubbed, and kneaded between the water current, the impeller, and the tank wall. The bonding force between the fibers is gradually destroyed, and the fibers are separated from the paper structure and mixed with other impurities to form a pulp suspension.

1.Tank

Usually made of wear-resistant and corrosion-resistant metal materials, such as stainless steel, with sufficient strength and capacity to accommodate the wet broke and water, providing space for the pulping process.

2.Impeller or Turntable

Installed on the transmission shaft and is the core component of the pulper. The shape, blade angle, and number of the impeller or turntable are carefully designed to achieve the best pulping effect.

3.Transmission Shaft

Connects the impeller or turntable with the drive motor and transmits power to make the impeller or turntable rotate at high speed.

4.Drive Motor

Provides power for the operation of the pulper. Its power and rotational speed can be selected according to the specification and production requirements of the pulper.

5.Inlet and Outlet System

The inlet is used to put the wet broke into the tank, and the outlet is used to discharge the pulped pulp suspension. Usually, corresponding pipes and valves are equipped to control the entry and exit of materials.

6.Control System

It is used to control the start, stop, rotational speed adjustment, operation time and other parameters of the pulper, and to achieve precise control and automatic operation of the pulping process.

1. Efficient Pulping

It can quickly decompose the wet broke into a mixed suspension of fibers and impurities, greatly improving the pulping efficiency and shortening the production cycle.

2. Fiber Protection

During the pulping process, through reasonable hydraulic and mechanical actions, the damage to the fibers is minimized, and the length and strength of the fibers are maintained, which is conducive to improving the quality of the subsequent pulp.

3. Strong Adaptability

It can handle different types, grammages, and specifications of wet broke and has wide applicability.

4. Convenient Operation

Equipped with an advanced control system, the operation is simple and it is easy to monitor and adjust the operating parameters of the equipment.

5. Energy Saving and Consumption Reduction,

The optimized structural design and power system configuration make the equipment consume less energy during operation, reducing the production cost.

6. Simple Maintenance

The structure is relatively simple, and each component is easy to disassemble and replace. The daily maintenance and servicing work is relatively convenient, reducing the maintenance cost and downtime of the equipment.
