The structure of the drum pulper mainly includes a roller-shaped drum, as well as the feeding hopper, transmission device, supporting roller device, blocking roller device, sealing device, shield and pulp pool, etc. The outer wall of the drum is inlaid with two large supporting rollers and a large gear.
The Type D Hydra pulper is a device used for pulping various raw materials such as waste paper and pulp boards. Through the hydraulic action and mechanical agitation, the materials put into it are quickly decomposed into a fiber suspension.
"High Consistency Hydro Pulper" is a piece of equipment used in the papermaking industry. It is designed to disintegrate and blend high-concentration (typically referring to a high solid content in the pulp) waste paper, pulp boards, or other fibrous materials to prepare a fiber suspension suitable for subsequent papermaking processes.
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.
The "Semi-dry Broken Pulper" is a professional equipment used for processing semi-dry waste paper and plays an important role in the field of papermaking and paper product recycling and reuse. In terms of working principle, the semi-dry broken pulper puts the semi-dry waste paper into the pulping tank. Through the rotating impeller or stirring device, with the assistance of water and chemical additives, the waste paper is stirred, rubbed, and impacted. Under the combined action of mechanical force and hydraulic force, the paper fibers are separated from other impurities to form a pulp suspension.
In the paper industry, the Drum Screen is an indispensable and crucial piece of equipment primarily utilized for the meticulous screening and profound purification of pulp. Its core function lies in precisely separating the fiber components that meet specific size, shape, and quality standards from the pulp mixture while efficiently eliminating various impurities such as sand grains, fiber bundles, plastic fragments, stickies, and overly large or small fiber segments.
Its main function is to effectively separate different types and qualities of fibers from the mixed pulp based on the physical properties of the fibers (such as length, fineness, flexibility, specific gravity, etc.), chemical properties (such as the surface charge and hydrophilicity of the fibers), or other related characteristics.
It is an advanced machine specifically designed for fine impurity separation. In the papermaking process, pulp often gets mixed with all kinds of impurities, and the presence of these impurities seriously affects the quality of paper and production efficiency.
In the papermaking industry, a "Ragger rope twisting machine" is a piece of equipment used to handle long and strip-shaped debris such as ropes, plastic bands, and cloth strips that are generated during the process of papermaking from waste paper.

Working Principle of Hydrapulper
The role of water
Water is a critical component in hydro pulping as it helps to separate the fibers from the raw material. Water is added to the tank where it mixes with the raw material to create a slurry. The slurry is then agitated using a rotor, causing the fibers to separate from the raw material.
The role of rotor
The rotor is the component responsible for agitating the slurry in the tank. It has blades that move the slurry and water mixture around the tank, causing the fibers to separate from the raw material. The rotor can be driven by a motor or connected to an impeller for additional agitation.
The role of screen plate
The screen plate is a perforated plate located at the bottom of the tank that allows the separated fibers to pass through while retaining any contaminants and impurities. The screen plate is designed to ensure the pulp produced has a consistent quality and to prevent blockages in the system.
The role of impeller
An impeller can be added to the rotor to provide additional agitation to the slurry. It is a disc-shaped component that rotates inside the tank and helps to create a vortex that improves the separation of fibers from the raw material.
The role of discharge valve
The discharge valve is located at the bottom of the tank and is used to remove the remaining water and contaminants from the tank. The valve can be adjusted to control the consistency of the pulp produced, allowing for customization based on specific paper production needs.
Types of Hydrapulper
Vertical hydraulic pulper
The main structure of vertical hydraulic pulper includes tank body, rotor (impeller), bottom knife ring and motor. Its working principle is to start the motor, so that the impeller begins to rotate, the pulp in the tank body along the axis of the center of the inhalation, from the circumference of the high-speed throw, the formation of intense turbulence cycle. This turbulent circulation and the tearing effect of the impeller wings make the slurry in the wet state strongly sparse and separate the fibers, while the fiber bundles rub against each other in the gap between the impeller and the sieve plate to increase the fibrillation. Vertical pulper can be divided into continuous pulper and intermittent pulper according to whether the operation is continuous or not, and can be divided into high concentration pulper and low concentration pulper according to the concentration level. Vertical pulper in various forms, but the main structure of the same form, a typical vertical pulper by the rotor, screen plate, working tank body and transmission mechanism, of which the rotor is the key component.
Horizontal hydraulic pulper
Horizontal hydraulic pulper is divided into [Volt type (horizontal) hydraulic pulper and drum type (drum type) hydraulic pulper two kinds. Volt type hydro pulper has a side-mounted rotor and an impurity collector in the lower part of the tank, and the other structures are the same as those of the vertical pulper. Drum type hydro pulper is mainly composed of feeding hopper, rotary drum, screen drum, transmission mechanism, base and platform, spray pipe and other parts, it is a kind of high efficient waste paper shredding equipment.
Check before starting: Make sure all parts of the equipment are in good condition, especially the key parts such as rotor, stator, screen, etc. are not blocked, worn and loose. At the same time check the electrical system, lubrication system, water supply is normal.
Start-up process: Gradually increase the water flow and speed according to the operating procedures, to avoid the impact of instantaneous high load operation on the equipment. Monitor the instrumentation to ensure that the pressure, temperature, speed and other parameters fluctuate within the preset range to ensure the efficiency and stability of crushing.
Feeding and crushing: According to the type of raw materials, water content and target pulp quality, reasonably control the feeding volume, crushing time and hydraulic impact strength. By adjusting the feed valve and rotating speed, the raw materials are fully crushed under the action of water to achieve the ideal fiber dispersion state.
Slag discharge and cleaning: Use the hydraulic shredder slag discharge system to discharge the unbroken impurities and coarse fibers to keep the system clean. Subsequently, the equipment is thoroughly cleaned to prevent residues from affecting subsequent production. When cleaning, the power should be turned off, and use water or special cleaning agents to ensure that there is no residue inside or outside the equipment.
Routine inspection and maintenance: After cleaning, close all valves and power supply, and carry out routine inspection and maintenance of the hydraulic shredder, such as replacing worn parts, replenishing lubricant, etc., so as to be ready for the next use. At the same time, make a good record of equipment operation, summarize the lessons learned in the process of use, and continuously optimize the operation process.
Maintenance of Hydrapulper
The operator should carefully check whether all parts of the equipment are in good condition, especially the rotor, stator, screen and other key parts, to ensure that there is no blockage, wear and tear, loose. At the same time, check whether the electrical system, lubrication system, water supply is normal, to ensure that the equipment is started in the best condition.
Regularly clean the debris and waste near the inlet and outlet to ensure the smooth flow of materials in and out. Clean the materials and residues accumulated on the blade and screen to avoid blockage and reduce the crushing efficiency. Check whether the chains, belts and gears of the transmission system are loose or worn, and adjust or replace them in time.
According to the manufacturer's recommendation, add appropriate amount of lubricant or grease regularly to ensure good lubrication of bearings and gears. Before adding new lubricant, clean the surfaces of bearings and gears, remove old oil and debris, and make sure the new lubricant is effective. When the equipment is not in use for a long time or the environment is humid, anti-rust measures should be taken, such as applying anti-rust agent or covering protective cover, etc., to prevent important parts from corrosion.
Check whether the safety equipments such as limit switch and emergency stop button are sensitive and reliable to ensure that the machine can be stopped in time in case of emergency. Adjust the gap and position of blade and screen to ensure the crushing effect and output. Regularly check the electrical system by professional personnel to ensure the safety and stability of the circuit to avoid safety accidents and equipment damage caused by circuit failure.
