Pulp & Paper

Pulp & Paper

The production process of the pulp and paper industry usually involves the mixing and handling of a large amount of slurry. The viscosity of the slurry is usually high and contains a certain proportion of solid particles, which places high demands on the mixer. Effective stirring can not only prevent the sedimentation of solid particles, but also ensure the uniformity of the slurry, thereby improving the quality and production efficiency of paper.

The Customized Solutions of Keheng Mixers

In the pulp and paper industry, customized design of mixers is essential to improve production efficiency and ensure product quality. Our mixers can be tailored to the specific needs of customers to cope with different working conditions and production environments, ensure that materials can be efficiently mixed, avoid sediment accumulation, and provide continuous and uniform mixing effects.

1. Efficient shaft sealing device to prevent leakage

Due to the high viscosity slurry and long-term equipment operation involved in the pulp and paper production process, shaft sealing devices are particularly important. Our mixers are usually equipped with efficient shaft sealing devices to prevent slurry leakage, which can be packing seals or mechanical seals, tailored to each working condition.
2. Customized design based on slurry characteristics and tank size

Pulp and paper mills use a wide variety of slurries, and differences in viscosity, particle size and type will directly affect the performance and effect of the mixer. Our design team will provide tailored solutions based on the characteristics of the slurry (viscosity, particles, size, etc.) and the size and shape of the tank.
3. Diverse material selection to ensure long-term stable operation

During the pulp and paper production process, the slurry often has strong acid, strong alkali or high temperature characteristics, which puts higher requirements on the material of the equipment. In order to adapt to these harsh conditions, we provide a variety of material options, including stainless steel, corrosion-resistant alloy steel, etc., to help customers choose the most suitable material to ensure that the mixer has stronger durability and corrosion resistance, extend the service life of the equipment, and reduce long-term maintenance costs.

Applications

1. Pulp Treatment

During pulp treatment, the main function of the mixer is to evenly mix fibers, fillers and chemicals. Side-entry mixers and top-entry mixers each have their own advantages and can provide the best mixing effect according to the characteristics of the pulp and the size of the tank. Especially in the pulp treatment process, the mixer can ensure the uniform distribution of fibers and fillers, avoid their sedimentation or aggregation, and ensure the quality and production efficiency of paper.
2. Suspension of Solid Particles in the Papermaking Process

During the papermaking process, it is often necessary to evenly suspend solid particles in the liquid. At this time, the role of the mixer is crucial. Side-entry mixers are suitable for smaller storage tanks and can effectively prevent particle sedimentation. The top-entry mixer can quickly disperse and suspend particles through its powerful stirring force to ensure the uniformity and stability of the pulp.
3. Wastewater Treatment

Pulp and paper mills generate a large amount of wastewater during the production process, which usually contains solid particles and harmful substances. The mixer can effectively keep solid particles suspended, promote chemical reactions or physical separation processes, and thus improve the efficiency of wastewater treatment. Whether side-entry or top-entry mixers, they provide reliable solutions to help pulp and paper mills achieve more efficient wastewater treatment.

Applicable Scenarios of Side-entry mixers & Top-entry Mixers

Top-entry Mixers

The installation method of top-entry mixers makes them very suitable for handling high-viscosity slurries. By installing vertically, top-entry mixers are able to provide strong stirring force, especially suitable for occasions where it is necessary to penetrate deep into the slurry and quickly and evenly disperse solid particles.

Side-entry Mixers

Side-entry mixers are ideal for many pulp and paper mills because of their compact design and suitability for smaller spaces. They are usually installed on the side of the tank and can provide lateral mixing force, which is essential for preventing sedimentation and evenly dispersing particles in the slurry. For low to medium viscosity slurries, side-entry mixers can provide efficient mixing without taking up too much space, especially suitable for environments with limited space.
