Product Description


The high pressure sieve basket, also known as the pressure sieve roller, is mainly used in the pressure sieve equipment to screen and separate the material before feeding. According to the screening direction of the material in the sieve cylinder, it can be divided into internal flow pressure sieve and external pressure sieve.

The pressure screen drum is an essential and important pulping screening equipment in the pulping process, so the quality of the screen drum directly determines the quality of the pulp screening, and the design, material and manufacturing process of the screen drum directly affect the fineness and efficiency of the screening.

The screen drum can remove coarse impurities and unqualified fibers in the pulp through the fine screen slit design, thereby improving the purity and uniformity of the pulp. This is essential to improve the quality and performance of the paper.
A high quality screen drum reduces energy consumption during the screening process and reduces pulp waste due to incomplete screening. This helps to reduce production costs and improve economic efficiency.


Application and Features



The screen drum is the core part of the pressure screen. Through its fine screen joint design, it can remove the coarse impurities and unqualified fibers in the pulp, so as to improve the purity and uniformity of the pulp.

The pressure screen drum can effectively protect the subsequent production equipment, avoid coarse impurities into the equipment to cause damage, and ensure the stable operation of the production line. In addition, the screening efficiency of the screen drum directly affects the production speed of the pulp, and the efficient and reliable screen drum can ensure the continuous supply of pulp and improve production efficiency.


The pressure screen drum has the advantages of high screening efficiency, long service life, and is not easy to clog.

Because the material enters the screen at a higher pressure along the tangent line, the qualified material can quickly pass through the screen drum and achieve efficient screening by centrifugal force. At the same time, the screen drum is made of corrosion-resistant and wear-resistant materials, which can resist the impact and wear of impurities in the slurry and extend the service life.

In addition, the design of the screen drum also considers the anti-clogging function to avoid the high-density accumulation of sediment and ensure the smooth screening.

Drilled sieve basket

The pressure sieve basket is a commonly used equipment in the paper industry, which is mainly used for the screening and separation of fibers to effectively remove impurities in the slurry and ensure the efficiency and quality of paper production. At the same time, it is also widely used in chemical, food, medicine and other industries, for the screening and grading of fine materials.

The sieve basket is an important part of the pressure sieve, and its working principle is mainly to filter and separate the slurry through the sieve hole. Under the action of pressure, the slurry passes through the sieve hole of the sieve basket, and the impurities are blocked outside the sieve basket, so as to achieve the purification of the slurry. The sieve size of the sieve basket can be adjusted according to the need to adapt to the screening needs of different sizes.

Common sieve basket materials include stainless steel, carbon steel, etc. These materials have good corrosion resistance and mechanical strength, which can ensure that the sieve basket can maintain stable performance in harsh working environments. In terms of manufacturing process, the sieve hole of the sieve basket is usually used with precision punching or cutting technology to ensure the uniformity and accuracy of the sieve.


Microporous screen basket

Paper machinery Microporous screen basket an important role in paper making process. Its main function is to filter and screen the black liquor to remove impurities and particles, so as to achieve the purification and recovery of the black liquor.

Specifically, the black liquid first enters the upper separation chamber of the filter in the tangential direction, and then spills over the circular cofferdam and flows from the top down into the filtration zone between the filter drum and the rotary cylinder. In this process, the heavy impurities in the black liquor are separated under the action of centrifugal force, settled in the trap, and periodically discharged from the fallout discharge pipe.

How do rotary cylinders contribute to controlled and precise rotation?

Rotary cylinders play a significant role in achieving controlled and precise rotation in various applications. Here’s a detailed explanation:

1. Fluid-Powered Actuation: Rotary cylinders utilize hydraulic or pneumatic fluid to generate rotary motion. By controlling the flow of fluid into and out of the cylinder, the rotation can be precisely regulated. This fluid-powered actuation allows for smooth and controlled rotation with high accuracy.

2. Adjustable Pressure and Flow: The pressure and flow of the fluid supplied to the rotary cylinder can be adjusted to control the rotational speed and torque. By varying the pressure or flow rate, the cylinder’s rotational characteristics can be fine-tuned to achieve the desired level of control and precision.

3. Position Feedback Devices: To enhance control and precision, rotary cylinders can be equipped with position feedback devices such as rotary encoders or potentiometers. These devices provide real-time feedback on the cylinder’s rotational position, allowing for accurate positioning and control over the rotation.

4. Servo Control Systems: Rotary cylinders can be integrated into servo control systems, which offer advanced control capabilities. Servo systems use feedback signals to continuously monitor and adjust the cylinder’s position, speed, and torque. This closed-loop control mechanism enables precise rotation and ensures the desired positional accuracy is maintained.

5. Speed and Acceleration Control: Rotary cylinders provide control over the rotation speed and acceleration. By adjusting the fluid flow rate or pressure, the rotational velocity and acceleration can be precisely controlled. This feature is particularly beneficial in applications that require smooth and gradual acceleration or deceleration to prevent jerky movements or damage to the equipment.

6. Positioning Accuracy: Rotary cylinders offer excellent positioning accuracy, allowing for precise angular displacement. By combining precise control of fluid flow and feedback from position sensors, the cylinder can accurately reach and maintain specific rotational positions. This level of positioning accuracy is crucial in applications that require precise alignment or synchronization with other components or processes.

7. Repeatability: Rotary cylinders exhibit high repeatability, meaning they can repeatedly achieve the same rotational position with minimal variation. This characteristic is essential in tasks that require consistent and repeatable rotational movements, such as assembly, indexing, or machining processes.

8. Compatibility with Control Systems: Rotary cylinders can be seamlessly integrated into various control systems, such as programmable logic controllers (PLCs) or computer numerical control (CNC) systems. This compatibility enables precise coordination and synchronization of rotary motion with other machine operations, ensuring controlled and precise rotation within the overall system.

What is a rotary cylinder and how does it function in machinery?

A rotary cylinder is a type of actuator used in machinery to convert fluid power into rotational motion. Here’s a detailed explanation:

Function and Operation:

A rotary cylinder is designed to generate rotary or swinging motion in a machine or system. It consists of a cylindrical housing with an internal piston or vane mechanism. The cylinder housing is connected to the machine or system, while the piston or vane is driven by hydraulic or pneumatic pressure.

When fluid pressure is applied to the rotary cylinder, it creates a force that acts on the piston or vane. This force causes the piston or vane to move in a circular or swinging motion, resulting in rotational movement of the output shaft or mechanism connected to the cylinder. The direction and angle of rotation depend on the design and configuration of the rotary cylinder.

Types of Rotary Cylinders:

There are different types of rotary cylinders, including:

  • Rack-and-pinion rotary cylinders: These cylinders use a rack and pinion mechanism to convert linear motion into rotary motion. The fluid pressure pushes the piston, which engages with the rack, causing it to rotate the pinion and generate rotary motion.
  • Vane rotary cylinders: Vane cylinders use vanes or blades that are pushed outward by fluid pressure, causing the cylinder to rotate. The vanes slide in and out of slots in the rotor, creating the rotary motion.
  • Gear rotary cylinders: Gear cylinders employ gears that mesh together to generate rotary motion. Fluid pressure drives the gears, causing them to rotate and transfer the motion to the output shaft.


Rotary cylinders find applications in various machinery and industrial systems where rotational movement is required. Some common applications include:

  • Rotary indexing tables
  • Robotic arms and manipulators
  • Material handling equipment
  • Conveyor systems
  • Machine tools
  • Packaging machinery

Rotary cylinders offer advantages such as compact size, high torque output, and precise control over rotational motion. They can be used in both hydraulic and pneumatic systems, depending on the specific requirements of the application.

It’s important to consult the manufacturer’s documentation and guidelines for specific information on the selection, installation, and operation of rotary cylinders in machinery.
